Are Modern Vehicles Maintenance Free?

In our auto video today we'll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that "modern cars are so reliable, they are virtually maintenance free".

Any good myth has some elements of truth. No offense, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn't so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.

Here are some examples;

• Some cars no longer require chassis lubrication. They're made with self-lubricating materials and have sealed joints. There's literally is no way to grease those joints.

-Chalk one up for the myth.

On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts up in the valve train that didn't even exist not that many years ago. These parts are very vulnerable to oil sludge.

• So, skipping an oil change here and there could lead to very expensive damage.

-A point to maintenance.

• Electronic ignition has eliminated replacing points.

-Myth gets a point.

• Fuel injectors on direct injection engines are very expensive to replace so one must be sure to get a fuel system cleaning on schedule.

-Point for maintenance.

I think you get the picture. As automotive technology advances, it eliminates or reduces some maintenance requirements. And maintenance becomes more critical for some items. Most others remain very similar to what they've always been.

So the maintenance mindset is still important for car owners if we want our vehicles to last a long time. The checklist may change over time, but there'll always be a check list.

Let me mention a couple of items on modern vehicles that folks need to be aware of. One of the most of the most important is timing belt replacement. Used to be that all engines had timing chains – you know, metal chains. They rarely broke.

It's cheaper to make engines with timing belts rather than chains, so replacing the timing belt is on most engines' maintenance list. The money the manufacturer saves by using a belt is more than off-set by what the vehicle owner has to pay to replace the belt. And it's a drop in the bucket compared to the cost of repairing the damage if the timing belt breaks.

So make sure you know when your timing belt needs to be replaced. You don't want to miss that. If you have 60,000 miles or more, break out your owner's manual or ask us at Moshe's Auto Care to check on the recommendation right away.

Another is sealed wheel bearing assemblies on some vehicles. As you might have guessed, it's cheaper to make a sealed unit than one that has access to inspect or service the wheel bearings. The problem is that when the bearings fail, you have to replace the entire unit, not just the bearings. That'll cost 5 or 6 times as much.

For our friends, we hope this has underscored the importance of knowing and following your maintenance schedule. Come in and see us at Moshe's Auto Care. You'll find us at 9200 Talbot Ave in Silver Spring, Maryland 20910 . Just give us a call at 301-588-4445.

Watching Your Check Engine Light

Did you know that most of the cars driving around carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in our area have as many as twelve networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle's functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do you know when there is a problem?

It's simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to Moshe's Auto Care to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

At Moshe's Auto Care we have special diagnostic equipment that will retrieve the trouble code from the computer and help us determine what is wrong. From there, we can fix it and get you back on the road.

Stop by if you're check engine light is on.

Winter Prep Service For Your Auto

When winter approaches in our area, we break out the sweaters, coats, boots and mittens. We want to be ready for winter conditions. Your vehicle needs to be ready for winter as well. The last thing you want is to get stranded out in the cold. You need your vehicle to be safe and reliable. It's a good idea to get caught up on any neglected maintenance items anytime - but the stakes are higher in the winter.

There are some specific things that we need to do to have our vehicle ready for winter. The most obvious is having the antifreeze checked. If the antifreeze level is too low, it can't properly protect your engine, radiator and hoses from freezing. If your car does not seem to be making enough heat to keep you warm, your antifreeze level may be low or you could have a thermostat problem. Get it checked out. If you are due for a cooling system service, now is a perfect time to have it done.

In the cold months around Silver Spring we always worry about being able to stop in time when it's slick out. The first thing to remember is to slow down and allow yourself plenty of room to stop. Of course, you want your brakes to be working properly. A thorough brake inspection will reveal if the pads or any other parts need replacing. Check with your service consultant to see if it is time to replace your brake fluid. It accumulates water over time which really messes with your stopping power.

It is a really good idea to have your battery tested. A battery's cranking power really drops with the temperature. If your battery is weak in the fall, it may not be up to winter. There is nothing like a dead battery in a snow storm.

Which leads us to an emergency kit. You should always have a blanket or something to keep you and your passengers warm if you get stranded. If you will be venturing away from civilization, pack more items such as food and water to help you survive. Keeping at least half a tank of gas is a good precaution if you get stuck and need to run the car to keep warm and it will help keep your gas lines from freezing up.

Winter always makes us think of our windshield wiper blades - usually during that first storm when they aren't working right. That's why it's a really good idea to replace your blades in the fall before the winter storms. If you live where there's a lot of snow and ice, you might want a special winter blade that resists freezing up. And be sure to have enough windshield washer fluid.

The final thing to consider is your tires. Any tire can lose pressure over time - up to one pound every six or eight weeks. For every 10 degrees the temperature drops you lose another pound of pressure. So if it was 80 degrees outside when you checked your tire pressure two months ago and now it's 40 degrees out, you could be down 5 pounds of pressure. That's enough to be a real safety issue and it wastes gas too. You may need special winter tires as well. Your tire professional can help you find the right tire design for your expected road conditions.

If you're getting winter tires, it is always best to put them on all four wheels. If you are only getting two, have them put on the rear - even if you have a front-wheel drive or four-wheel drive vehicle.

This is a very important safety measure recommended by tire manufacturers. Sliding or fish-tailing on ice and snow is a matter of not having enough traction at the rear end. That is why your newest tires should always be on the rear.

Cooling System Components

Today we want to talk about a very important system in our cars – the cooling system. It’s one of those things that you don’t give much thought to until it fails and then you’re stranded by the side of the road.

Cooling systems fail more often than any other mechanical system – usually because of neglect. Don’t you hate it when something breaks, and you could have done something to prevent it?

The good news is that if you take care of your cooling system it can keep working for the life of your car.

Here at AutoNetTV, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, the thermostat, the radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.

It sounds complicated, but we don’t have to be experts – we can leave that to our honest service technicians at Moshe's Auto Care. But, having an overview will help us remember to take care of our cooling systems.

Most people would be surprised to know that burning fuel in your engine produces up to 4,500 degrees of heat. And all that heat has to be dealt with. If the heat can’t be drawn off the engine, the pistons will literally weld themselves to the inside of the cylinders – then you just have to throw the engine away and get a new one. That would cost thousands of dollars.

Now the water pump is what forces the coolant through passages in the engine to absorb heat. The pump is driven by a belt that needs replacement from time to time. And the water pump will eventually wear out and need to be replaced. Spending some money on replacing the belts and water pump is much less than the cost of repairing the massive damage that can be done when an engine seizes.

There’s another little part of the coolant system that protects the engine. It’s called a freeze plug. If you remember from high school chemistry, water expands when it freezes. In very cold areas, the coolant can actually freeze when the vehicle is left sitting.

It is hard to believe, but the expanding frozen coolant can actually crack the engine block. The freeze plugs fit into the engine block. They fit tight enough to withstand the pressure of a running engine, but can expand or pop out if the coolant freezes. These little things save a lot of engine blocks.

That brings up a good point. An engine has to work in all kinds of temperatures – extremely hot as well as very cold. How does the cooling system adapt to external temperatures as well as varying operating conditions?

Well, it’s much like the way you keep your house at a comfortable temperature all year round – with a thermostat. The thermostat in your car controls how much coolant flows through your engine. When the engine is cold, it restricts coolant flow until the engine comes up to an efficient operating temperature. Then it starts opening up to move more coolant to keep the temperature within a specified range.

The thermostat needs to be replaced from time to time as well. It’s easy to diagnose a failed thermostat and is fairly inexpensive to replace. We can do this for you at Moshe's Auto Care in Silver Spring, just give us a call: 301-588-4445. Now we’ve been talking about all this heat we’ve got to get rid of, but haven’t really talked about where it goes. That’s where the radiator comes in. The hot coolant passes through the radiator. Air flows past the cooling fins and cools the coolant.

The radiator has two tanks that hold coolant: sometimes one the top and bottom or one on either side. If you have an automatic transmission, one of the tanks will also contain a second tank that cools the transmission fluid. Large SUV’s and trucks often have a separate transmission cooler. So when you drive around Silver Spring, the air is forced past the radiator. But driving doesn’t produce enough air flow. So the radiator has cooling fans that force fresh air over the radiator. These fans may be powered by a belt or by electric motors.

Now, you also have something called a heater core. The heater core is like a mini radiator. A small fan blows air over the heater core and into the passenger compartment of your vehicle. That’s how you warm your car when it’s cold out.

Next is the radiator cap. With most newer cars around Silver Spring, you never remove the radiator cap, except to replace it. You add coolant through the overflow tank. The radiator cap is also called a pressure cap, because its job is to maintain pressure in the cooling system.

High pressure raises the boiling point of the coolant, so it cools more effectively even in very demanding conditions. That is why you need to replace the cap from time to time. They recommend changing it out every time you replace your coolant.

Coming back to the overflow tank, it is needed because when the coolant gets hot it expands and the overflow holds the extra volume. The tank helps maintain the proper level of coolant and keeps air out of the system. You should never open the radiator cap or over flow tank when the engine is hot. This could lead to serious burns.

What else do we need to do to keep our cooling systems working well? Well, there are the hoses that hook all of these pieces together. They’re obviously very tough to deal with the pressure and high temperatures. But they do get worn. Sometimes they get spongy from the heat. Sometimes they lose their connection to the radiator, water pump, etc. It’s a great idea to have your Silver Spring service center inspect your hoses at least once a year and replace them, if needed, before they break.

Moshe's Auto Care can help you check your cooling system and make any necessary adjustments or repairs. Give us a call at 301-588-4445.

What To Do In Case Of An Accident in Washington DC

Screeching tires, crunching metal – it’s an accident! If you’ve ever been in a car accident in Washington DC, even a minor one, you know how upsetting it can be. It’s hard to think straight and know what to do.

Let’s review what you should do in case of an accident:

When an accident occurs, you should always stop. Leaving the scene of an accident in Silver Spring is considered a crime - even if it’s not your fault. And hit and run penalties are fairly severe, possibly resulting in steep fines, loss of your Maryland driver’s license or even jail time.

Your jurisdiction may require that you try to help someone who is injured by calling for help or performing first aid if you are able. Warn other motorists by putting out flares, using your flashers or lifting your hood. Call emergency services as soon as possible. Tell the operator if medical or fire help is needed.

Always file a police report. It’s tempting to skip this if everything seems to be ok. But without a police report, the other guy can say whatever he wants about the accident later, and you’ll not have an objective report to help defend yourself. Discuss the accident only with the police. Emotions are strong after an accident and we naturally want to talk about it – don’t. Never admit fault or guilt to anyone including the police officer. Sometimes we may feel at fault, but in the eyes of the law, the other guy is responsible.

Truthfully give the officer the facts: such as "I was going thirty miles an hour" not "I wasn’t speeding". Remember, anything you say to the officer or anyone else can be used against you.

Also get the officer’s name and ID number and ask where you can get a copy of the accident report.

Get the facts on the driver and owner of the other vehicle:

• Name
• Address
• Phone number
• Date of birth
• Driver’s license number and expiration
• Insurance information

Also take down a description of the other vehicle, license plate and vehicle identification number. Most auto insurance companies don’t record license plate numbers, so the VIN number is the best way to track the vehicle.

Ask witnesses, including passengers, to wait for the police. If they can’t wait, ask for contact information and request that they write a brief description of what they saw. If someone refuses to leave their name, write down their license plate number so the police can track them down later if necessary. Always call your insurance agent or your insurance company. Call or see a physician if you think you may have been injured. For vehicle repairs, call Moshe's Auto Care at 301-588-4445

Moshe's Auto Care Often Asked About Premium vs. Regular Gas

People in often ask the question: "Will using premium gas make my car run better?" The answer is simple. But first, let's talk about what exactly premium gasoline is.

Different grades of gasoline have different octane ratings. Regular gasoline has the lowest octane rating and premium the highest. Most gas stations also carry a mid-grade that falls in between the two. The octane range for the different grades of gas varies by region due to altitude differences.

Engines require different octane ratings because of design differences. For example, turbocharged engines usually require premium gas.

There's a sticker on your gas tank filler lid that tells you the minimum octane rating your manufacturer recommends.

For help identifying the type of gasoline your engine needs, come by;

Read your owner's manual carefully to see if it's acceptable to use lower grades. With some cars it is; the engine control computer can adapt. You’ll lose some performance, but won't do damage. With other engines, using a lower grade of fuel could result in serious damage; so you don't want to save a couple of bucks at the pump only to pay it out a hundred fold at the repair shop.

Your car will run best on the grade of gasoline recommended by the manufacturer.

Today's computer controlled vehicles are optimized to run well on the recommended grade of fuel. Using a higher grade than is recommended will not give you any additional performance or better fuel economy.

Regulations require detergents for all grades of gasoline, so your engine will have the same protection, regardless of the grade of fuel you use. If you do hear some knocking or pinging from your engine, take it seriously and get your sedan into Moshe's Auto Care. It may be a sign that you need a tune-up or some other repair.

In times of high gas prices, we're all conscious of making our fuel dollar go further as we drive around. Be sure to use the right gas for your car. Keep your tires properly inflated and your vehicle well maintained and you will get the best fuel economy possible.

Coolant Antifreeze Service In Silver Spring Maryland

You may know that most automotive failures in our area are tire related, but do you know the second most common cause for vehicle failure? Nope, it's not teenagers. It is the coolant system. But, if you take good care of your coolant system, it will take good care of you.

A car's engine creates a lot of heat - so much heat, that if it is not properly cooled, the engine can lock up, resulting in massive damage and repair bills. But when everything is working right, your engine operates at the proper temperature and all is well. Without antifreeze in your cooling system, the water could freeze and cause engine damage. This could be very expensive, not to mention inconvenient.

The right mix of water and antifreeze protects the engine against damage from freezing and overheating. Antifreeze also protects the coolant system against corrosion that could cause the system to fail. The thing to remember is this: coolant system failure is very common, but it is also very easy to prevent. Moshe's Auto Care knows the manufacturers' recommendations, and can tell you when the coolant needs to be changed. They can also perform a coolant system service.

Even the best antifreeze cannot completely protect the coolant system from harmful deposits forever. The anti-corrosion additives are used up over time, so the coolant must be replaced. A coolant service cleans out the system and replaces the old fluid with fresh coolant. A coolant system service is a low-cost way to protect against major engine repairs down the road. Prevention is the key. Be sure to watch out for the two main warning signs: if your temperature gauge is in the "hot" zone or if you get a message warning you to check your coolant. If you take a look under the hood, you will see the coolant overflow bottle. You can see there are lines that indicate the proper level of coolant ... if your engine is cold - or if it is hot.

You can add water or antifreeze to that bottle yourself, but be careful. First, you never want to open the radiator pressure cap. The steam could severely burn you. Second, try to get to your service center immediately if your coolant is low. If that is not possible, follow the directions in your owner's manual. Third, remember that you need a proper mixture of water and antifreeze, or you will damage your engine. If you make an emergency addition to your cooling system, follow-up with your service center where they can make necessary corrections. Fourth, not all cars use the same type of antifreeze.

You will need to check your owner's manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. If you're not sure, ask us at Moshe's Auto Care for guidance.

To Save Gas Around Silver Spring: Keep Up with Your Scheduled Service

One topic that hits the news everywhere on a regular basis is the price of gas. The answer for some people in our area is to buy a more fuel efficient vehicle. For the rest of use, we need to improve our fuel economy anyway we can.

Following recommended service intervals by coming into Moshe's Auto Care is one of the best ways to keep your car running efficiently. That means better fuel economy. When you give it some thought, it only makes sense. Dirty oil or transmission fluid can’t lubricate or clean. That means more drag which reduces fuel economy.

Keeping up with scheduled oil changes and transmission services will save gas.

Dirty engine air filters are another efficiency pirate. They rob your engine of enough air to effectively burn the fuel, so you need more gas to get the job done. Replacing a dirty air filter can pay for itself in fuel savings before the next oil change.

You can imagine what dirty fuel injectors can do to your sedan as you drive around. If your owner’s manual recommends a fuel system cleaning, come into Moshe's Auto Care and ask us to get it done for you.

A simple, but very effective way to save gas is to keep your tires properly inflated. Low tires can cost you up to a mile per gallon. Check your tire pressure when you gas up – or at least once a month.

Better Service - Better Economy

The hottest news story may be different everyday, but there’s one topic that seems to come up over and over again – the price of gas. But we’ve found several basic things that any vehicle owner can do to greatly reduce their gas consumption, save money, and help the environment. You can really impact your fuel economy by how you drive – but first, here’s a review of things you can do for your car that’ll save gas no matter how you drive.

The first one is keeping your tires properly inflated. That can save two miles per gallon. Driving on low tires is like driving through sand – your car just has to work harder. Most service centers will fill up your tires for free, so just ask your service advisor. Also, make a habit of checking your tire pressure whenever you get gas in your car. Many area gas stations have an air hose you can use for free.

Another important item is to keep your air filter clean. An air filter all clogged up with dirt and bugs doesn’t let enough clean air through to efficiently burn fuel. Using a dirty air filter will cost you almost two miles per gallon in reduced fuel efficiency. And worn spark plugs can cost another two. A spark plug can fire as many as 3,000,000 times for every thousand miles driven. Check the owner’s manual for replacement recommendations.

The biggest item is the oxygen sensor. This device provides the engine management computer with information it needs to fine-tune the fuel/air mix. When that’s messed up it can cost up to three miles per gallon. And of course, there’s dirty or substandard oil. Dirty oil causes extra drag. The wrong grade may be too thick. That’s another .4 miles per gallon right there.

One item drivers seldom think about is their gas cap. A worn, loose or missing gas cap can cost another two miles per gallon. Adding up all of these worn, missing or sub-par items leads to a total of almost 11.4 miles per gallon in reduced fuel efficiency! And with current gas prices in our area, the cost really adds up. Taking care of these simple maintenance items will save big bucks at the pump.

Now most people aren’t missing on all of these items, but think about which ones might affect you right now! And don’t forget tune-ups, dragging brakes, low transmission fluid, fuel system cleaning, wheels out of alignment, PCV valve, fuel filter and other key services spelled out in your owners’ manual.

Moshe's Auto Care knows all this stuff and can tell you when you’re scheduled to take care of each item. Please give us a call!

Moshe's Auto Care On Your Serpentine Belt

Today we’re going to be talking about serpentine belts for our customers. Let’s start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That’s the device that makes electricity to power the vehicle and recharge the battery. Then there’s the air conditioning compressor that makes cool air for you while you're driving around this summer.

The power steering and power brake pumps are driven by the serpentine belt in most vehicles. Those pumps make the pressure that assists your steering and braking.

In many vehicles, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars, the water pump is driven by the timing belt.

The radiator cooling fans on some vehicles are also driven by the serpentine belt. Some have separate electric motors. That’s really a lot of work for one belt.

But modern engine design has a single belt that snakes around the front of the engine and drives most if not all of these accessories. Serpentine belts do a lot of work, but they’re tough and can last for thousands of miles.

Just how long will they last? That’ll vary for each individual car in our area. Your manufacturer will have a recommendation for when it should be changed, but it could need it sooner. The good news is that a visual inspection can reveal a belt that’s getting close to failing.

Moshe's Auto Care can look at the belt: if it has more than three or four cracks per inch it needs to be replaced. A deep crack that’s more than half the depth of the belt - replace. Frayed, missing pieces, a shiny glazed look? It’s out of there.

What’s involved in replacing the belt? First the old belt is removed. Then a new one is fitted around all the pulleys for the accessories and the drive. There’s a special pulley called a tensioner.

This pulley is mounted to the engine block with a spring loaded arm. Its job is to apply the correct amount of tension to the belt to keep it from getting loose and maybe slipping off. Because the spring in the tensioner pulley wears out, AutoNetTV recommends replacing them at the same time as the belt. It just makes sense.

What are the warning signs that there’s a problem with the serpentine belt? You may hear a squealing sound from under the hood when accelerating. A loose belt might give you a slow, slapping sound.

What do you do if your belt breaks? If you’ve actually had that happen on the beltway, it can be a little scary. Often the first thing you notice is that you have no power steering or power brakes. Don’t panic – you can still steer and brake, but you’ll have to do the work. It’ll be harder to steer and you’ll need more time and effort to stop, so plan accordingly.

Your dashboard will light up will all kinds of warnings. You’ll see a warning about your cooling system if you have a water pump that’s driven by the serpentine belt. This is very critical because without your cooling system working, your engine will overheat. If you don’t stop you’ll have massive engine damage, maybe to the point that you need a new engine. Pull over as quickly as you safely can. Open your windows and turn the heater on full blast to provide a little engine cooling and pulled over as soon as possible.

The battery light will come on because the alternator isn’t working. If your car’s water pump isn’t driven by the serpentine belt, you’re not in danger of overheating so you can drive a little further if necessary. But the battery will run down to the point where the car won’t run and will just shut off. You don’t want that to happen while you’re driving in our local traffic.

Remember, this does not have to happen if you replace your serpentine belt on schedule. Ask Moshe to check your belts and hoses from time to time so you can take care of them if they need to be replaced prematurely.
