Most Richmond drivers wait for their air conditioning to fail before they service it at Duffy’s Repair Service. That’s because many Ashland and Ashland motorists don’t really understand that automotive air conditioners need periodic service. Let me share some of the reasons why they fail.

First, like every machine, the SUV air conditioner parts need lubrication. The lubricant is actually mixed in with the refrigerant (that’s the stuff that makes the air cool). So sometimes, even though the air conditioner is still making cool air, the oil that lubricates the parts has just been used up: and unlubricated parts can fail in all Virginia cars.

Now here’s a tip for Richmond drivers: You should run your air conditioner every so often during Virginia winters. This circulates the lubricant to help keep the seals from drying out.

The air conditioner actually removes some of the moisture in the air. So if you have trouble with fogging on your windshield during Virginia winters or during a rain storm, running the A/C on the defrost setting should help. Now on some Richmond cars you can’t run the A/C at the same time as the defroster. Don’t ask me why, but I suspect lawyers were involved.

Also, air and water can get into the A/C system. That can reduce the efficiency of the system and also lead to corrosion that causes damage. Richmond drivers should periodically purge the system and replace the refrigerant to clear out the air and water.

Ashland drivers should be aware of early warning signs of trouble: One might be that the air’s not as cold as it used to be. You may hear an unusual noise when the A/C cycles on. Those are signs to get your vehicle into Duffy’s Repair Service in Ashland before the damage gets worse.

So following the recommended service intervals in your SUV owner’s manual can help prevent mechanical failure of your air conditioning system. You’re A/C system contains some expensive components like the compressor, condenser, dryer, etc. Anything Mechanicsville and Ashland car owners can do to lengthen the life of their A/C is well worth it.

So you love our job, and your family life is great: You have achieved balance. But can you the same for your wheels? You can tell if your tires are out of balance by vibrations at higher speeds. If one of the front tires is out, you feel the vibration in the steering wheel. If it’s a back tire, you’ll feel the vibration in your seat.

Tires and wheels are pretty heavy. When a tire is mounted on a wheel, it is usually not perfectly balanced. So the tire technician will spin the tire on a machine to determine where it’s too heavy. He will then place weights on the wheels in strategic locations to balance it out. When a tire is out of balance, it actually bounces down the road instead of rolling smoothly. Since the average size tire rotates at about 850 revolutions per minute at 60 MPH, it is actually slamming into the pavement 14 times a second. That’s where you get your vibration.

Most people are surprised at how smoothly their car rides after balancing all four wheels.

Most high-quality tires hold their balance pretty well. They just get out of balance gradually with normal wear and tear. If you suddenly feel a vibration, it is probably because you lost a wheel balancing weight along the way. Definitely get a balance if you feel a vibration, change your rims or have a flat repaired. Putting off a needed balance job leads to excessive tire wear, wear to your shocks, struts, steering and suspension parts. wheel balancing not only improves your ride and handling, but also can save you some big repair bills and possibly an accident. Additionally, you will get better gas mileage.

Some people have their tires balanced at every rotation. Others do it every other time. Check your owners’ manual for your requirements, or ask your technician. Doing thus will put you on the path to mechanical wheel balance

No one in Ashland Virginia likes high fuel prices. But if one good thing has come about, it’s that people are really focused on how to reduce their fuel consumption. North Americans literally drive billions of miles less each month during times of high fuel prices. But we still need to drive, so it makes sense to try and increase our fuel economy however we can.

Let’s look at a real life example of one of our AutoNetTV producers. He has one of those really big SUVs. Lots of kids and horses to haul around, you know. His family was planning a four day camping trip. Here’s what he did to cut his fuel costs:

First, he installed a new, high flow engine air filter. Then he had his service center change his oil, flush his cooling system and service his front and rear differentials along with the transfer case. He also had a fuel system cleaning, replaced his PCV value and breather element. He also made sure his tires were up to the recommended pressure.

Now this cost several hundred dollars. But keep in mind, it all needed to be done anyway – it was all scheduled, and some of the work was overdue.

So he headed out, loaded with nine people and pulling a ton of trailer with everything needed for four days of camping. When the trip was over, he had turned in the best fuel economy he had ever gotten on that vehicle. It had improved 25 percent. He saved $48.00 on that trip alone. And the savings keep on coming every day.

Here’s a quick summary of what you can do to save fuel in Ashland Virginia. First get caught up on your routine maintenance. Nearly every scheduled service item can save you some fuel. If its time for a tune-up, git’er done. That’s a big item.

If your check engine light is on, have your Ashland Virginia service center at Duffy’s Repair Service figure out why and fix it. Check engine problems can be real gas wasters.

Proper tire pressure and wheel alignment can really help as well. Try not to carry around a bunch of stuff. An extra hundred pounds can cost a mile per gallon.

Now you may not want to hear this, but the single biggest fuel waster for most people is their right foot. Zooming away from stop lights and hot rod lane changes really waste fuel. Take it easy, don’t speed and plan ahead.

Finally, you may have noticed that we haven’t mentioned any magic pills or devices that will double your mileage. That’s because there aren’t any. Some may help a bit, but there are a lot are scams.

Do some research and check with your service advisor at Duffy’s Repair Service before spending your hard earned cash.

You may know that all 2008 model year and newer cars, mini-vans and light trucks in Ashland come with a tire pressure monitoring system. Many slightly older vehicles around Ashland have these systems as well. A tire pressure monitoring system – called TPMS – consists of sensors on each wheel that measure tire pressure.

If tire pressure drops 25 percent below the manufacturer’s recommended pressure, the sensor sends a signal to a monitoring unit that causes a warning to light up on the dashboard. When you see the warning light, you know it’s time to put some air in your tires.

There are many benefits to driving with properly inflated tires around Ashland. First is cost savings. Running at the correct air pressure improves fuel economy. Driving on under-inflated tires is like driving through sand – it drags down your fuel economy. You’ll also see longer, more even tread wear so your tires’ll last longer.

Another important benefit of properly inflated tires is increased safety. Under-inflated tires become hotter and that heat can actually lead to tire failure – possibly resulting in an accident. Your car and the tires themselves will just perform better and more safely around Ashland with properly inflated tires.

Local Ashland consumer groups, law-makers and vehicle manufacturers advocate TPMS systems hoping that they will save lives, property damage and inconvenience. While you can’t put a value on saving a life, we keep in mind that TPMS systems will carry a cost.

The systems themselves are added into the price of the car. The batteries in the sensors will have to be replaced from time to time. Parts will break and need to be replaced. In colder climates around Virginia, ice and salt are frequent causes of failure.

In addition, there are other behind-the-scenes costs to be aware of. Every time a tire is replaced, repaired, rotated or balanced, the tire technician has to deal with the TPMS system.

Your service center (Duffy’s Repair Service) must purchase equipment used to scan and reactivate the TPMS system after every tire service. Because older tire change equipment can damage TPMS sensors, your service center may need to buy expensive, new tire changers.

Since there is no uniformity among manufacturers, technicians need to be trained on several TPMS systems. These behind-the-scenes costs are very real to your service center.

That’s why they are anxious for you to understand the financial impact of TPMS systems. In the past, they’ve been able to quickly and cheaply provide tire services, and then pass the low cost on to you as an expression of their good will. But now even these simple jobs will take much longer.

Sensors will need to be removed and reinstalled. Even a tire rotation will require that the monitor be reprogrammed to the new location of each tire. When a car battery is disconnected, the TPMS system will need to be reprogrammed.

So when you start so see the cost of tire changes, flat repairs and rotations going up, please keep in mind that it’s because of this new safety equipment. Duffy’s Repair Service just wants to keep you safely on the road – and we’re committed to do so at a fair price.

It’s important to remember that the TPMS warning only comes on when a tire is severely under-inflated. You’ll still want to check your tire pressure on a regular basis. At every fill-up is best, but you should check pressure at least once a month. Here’s wishing you safe travels.

People in Ashland have been hearing a lot about higher oil change intervals these days. Maybe you’re wondering: What are the key issues?

Some new vehicle manufacturers in Ashland are now recommending much higher oil change intervals than they have in the past. As much as 5,000 to 8,000 miles or more. This practice came under scrutiny when four of the largest new car manufacturers announced that owners like those in Ashland were experiencing engine damage resulting from these higher oil change intervals.

The manufacturers’ standard oil drain service for particular vehicles was scheduled at around 7,500 miles. People following these recommendations were experiencing engine damage. It turns out that oil sludge was building up. This caused small oil passages to clog and engine parts to fail.

What causes oil sludge? It’s a factor of time and mileage. There are hot spots in every engine that cause oil burn off that leads to sludge. Also, water from normal condensation can build up in the oil. This water also creates sludge. Severe driving conditions lead to more rapid sludge formation.

Severe driving around Ashland includes short trips under four miles or trips under ten miles in freezing conditions. The engine just doesn’t get warm enough for the water in the oil to evaporate.

Severe conditions are at the heart of the problem. Stop-and-go driving, towing, dusty conditions, heavy loads, very hot or very cold temperatures, a car top carrier – these are all conditions that would suggest that the severe service schedule should be considered.

The severe service schedule has much shorter oil change intervals. People in Ashland just need to honestly evaluate how they drive to determine if they should change their oil closer to the severe service schedule, or to the standard schedule.

Some types of SUV will give oil change reminders. But it’s important to know how that reminder is determined. For some, the reminder simply comes when the standard mileage interval has rolled around. Others use a computer algorithm that takes into consideration the number of cold starts, trip length, engine temperature and so on. It’s programmed to approximate where on the standard/severe service spectrum you fall. Some more expensive vehicles actually have sensors that test the cleanliness and effectiveness of the oil.

For the rest of us, better safe than sorry should be the guiding principle. Talk with your Ashland service advisor at Duffy’s Repair Service and work it out together. Find out what kind of oil the factory sends out in your vehicle. Sometimes it’s a premium grade that costs more than standard oil – but it may be what’s needed to meet a higher factory recommended interval.

If you’re realistically conservative, standard grades of oil will take care of you year after year. If you want to push the limits, ask for a premium grade oil to give you extra protection.

So, what happened with those manufacturers with the problems from higher oil change intervals? They ended up extending the engine warranty for parts that were affected by oil sludge. But they had a stipulation – they lowered the oil change interval and the vehicle owner had to provide proof of oil changes at the new lower interval to keep the extended warranty.

No matter how well they’re made, cars in Ashland Virginia will have design or manufacturing problems.

And when the government thinks a problem is really serious for people in Ashland Virginia, they require the manufacturer to issue a recall notice and fix the car free of charge. The manufacturer then tries to contact everyone in Ashland Virginia who owns that type of car to get the recall work done.

These recalls always affect safety, so take them seriously. It’s easy to see if a vehicle’s being recalled.

The government has links on its websites, or just visit AutoNetTV for links.

There are many websites with free recall information and searches. There’s CarFax, AutoByTel and the DMV.

Recalls are serious, but not all that common. But sometimes there are less significant issues, and for these, manufacturers issue a Technical Service Bulletin, or TSB, that tells service centers like Duffy’s Repair Service how to repair a frequent or difficult problem.

The pros get updated information through subscription plans, also available in consumer versions for a reasonable cost.

So when vehicle recalls occur, get the work done, and keep you and yours safe.

Ever heard the sad tale of a staggering repair bill from a broken timing belt? Bad news. Let’s take a lesson from their woes and remember to think about our timing belt.

First, let’s review what a timing belt does. The top part of the engine, over the cylinders is called the cylinder head. The head contains the valves. There’s at least one valve that lets the fresh air into the cylinder. This air, mixed with fuel, burns to create power. Then another valve or two open to allow the exhaust out of the engine. Each cylinder has 2 to 4 valves – that’s 12 to 24 valves for a V-6, up to 32 values on a V-8. The opening and closing of the valves is done by a camshaft. The timing belt uses the rotation of the engine to drive the camshaft which opens and close the valves. It’s called a timing belt because it has to be adjusted to rotate the camshaft to keep proper time with the engine so that everything’s in sync.

The timing belt is a toothed rubber belt . But some cars use a timing chain or timing gears instead of a belt. Timing chains and gears are much more durable, but manufacturers are using belts more because they are quieter – and cheaper. If you have a small or mid-sized passenger car, crossover or mini-van, chances are you have a timing belt.

Unfortunately, timing belts fail without any warning. That shuts you down right away. A technician can inspect your timing belt and look for cracks and looseness. But getting to the belt to take a look can be almost as much work as changing it on some cars. That’s why manufacturers recommend replacing the belt from time to time. For most vehicles it’s from 60,000 to 90,000 miles or 95,000 to a 145,000 kilometers. If your owners’ manual doesn’t specify an interval ask your service advisor.

One AutoNetTV producer has had two timing belts fail. The first was while he was waiting at a stop light – that repair cost several thousand dollars. The second was while driving on the highway – that one cost more than twice as much. Both had the cars out in the shop for three weeks. His cars had what we call “interference engines”, meaning that the valves and pistons are very close to each other. If the timing belt slips even one notch, the pistons will slam into the open valves. That’s why our friend’s highway failure was so much more expensive – his engine was traveling so fast that the valves were smashed and they chewed up the cylinder head.

A non-interference engine will just shut down if the timing belt breaks. You’re stranded, but the engine doesn’t suffer permanent damage. In both cases, our hapless friend was just a couple oil changes past the recommended interval for changing the timing belt. This is one of those things that you just cannot put off. Now replacing a timing belt is not cheap – but repairs for a broken belt can be many times as much.

Check your owners’ manual right away – especially if you have more than a 60,000 miles or 95,000 kilometers. You may need to get that belt replaced right away. And on many cars, the timing belt drives the water pump. So, it may be a good idea to replace the water pump while you’re at it because 90% of the work required for the new pump is already done with the belt change. Doing both at the same time saves you a lot of money because as they say, “timing’s everything”. Parts, Timing Belt

So you have some exciting plans for the Virginia weekend. You’re going to take some of your Ashland, Virginia friends out on the boat for some water skiing. Of course, you’ve gotten the boat all ready. And you haven’t forgotten about your tow vehicle. You’ve gassed it up and even vacuumed it out. But you want to make sure that your SUV maintenance is up to date.

Think about it – heavy traffic on the way out of Ashland. There’s hilly terrain as you get to the lake. Some dirt roads – and its going to be pretty hot in Ashland this weekend. And all the time you’ll be towing around several thousand extra pounds. That all adds up a lot of severe strain on your engine, brakes and transmission.

Let’s just consider the transmission. It’s going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What’s a fun little blast to the local Virginia lake for you is really severe duty for your transmission.

It’s important to have enough transmission fluid. If it runs low, the transmission will run hotter and won’t have the protection it needs to cope with the added stress of towing. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced at Duffy’s Repair Service on schedule to make sure it runs efficiently.

An automatic transmission contains a maze of passages through which the fluid has to pass to keep it shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems.

Neglect your transmission for too long, and it can fail. You really don’t want to pay for a major transmission repair.

This reminds us of how much of our driving around Ashland, Virginia is under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips, driving in very hot or very cold weather. Dusty roads and city driving around Ashland, Virginia add to the strain. Basically, any driving that’s not at highway speeds or under ideal conditions.

While you have your vehicle in, ask for a trip inspection. Your Ashland, Virginia service technician at Duffy’s Repair Service will check your belts and hoses and let you know if your brakes are in good shape.

Now, don’t forget the sunscreen.

The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around Ashland Virginia use fuel filters.

For more information about your fuel filter, visit Duffy’s Repair Service or come by our shop located at 9974 Lickinghole Road in Ashland, Virginia 23005.

Generally speaking there’s not a lot of dirt in our Ashland Virginia auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That’s because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your SUV is five years or older, it can actually have a fair amount of sediment built up.

That just means that the fuel filter has to work harder as your SUV ages. It’ll get clogged sooner and need to be replaced more often.

A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That’s because enough fuel is getting through around town, but when you need more fuel for speed, enough just can’t get through the filter. Obviously, that could be dangerous if your car or truck can’t get enough power to get you out of harm’s way.

For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.

This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don’t want to cause them damage just because you didn’t spend a few bucks to replace a fuel filter.

You know, in a way, the fuel filter can be the poster child for preventive maintenance. It’s a little part, it’s simple and it’s cheap to take care of. But if it’s neglected, it could lead to thousands of dollars of repair bills.

Those auto service schedules in your owner’s manual are there for a reason. If ever you don’t understand a recommended service, just ask your Ashland service advisor at Duffy’s Repair Service. We’ll be happy to explain.

This is something really amazing: For every gallon of gas your Ashland car burns, it uses 12,000 gallons of air. All of that air has to be filtered to keep your engine clean.

That’s like a hundred gallons of air every block! The engine air filter is just another example of a very inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn’t, well, it can lead to costly problems. Of course, your manufacturer recommends intervals for changing your air filter. But like most service intervals, where and how you drive your car affects when your filter needs to be changed.

Dusty conditions in and around Ashland or polluted city driving means you’ll need to change your filter more often. Your Duffy’s Repair Service technician can check your filter for you. In fact, it’s often a routine part of an oil change.

When you think about it, a clogged air filter won’t allow as much air through as a clean filter. Your car needs this air to efficiently burn its fuel, giving you better fuel economy and performance.

Dirtier filters don’t work as well as clean ones. A filter can only hold so much, after that, it allows dirt to pass right into your engine. Air filters come in all shapes and sizes. They also come in different grades. There are high performance air filters available for most cars. These high performance filters cost a little more, but they increase horsepower and may improve fuel economy to boot.

So have your air filter checked. If it needs replacing, it doesn’t cost very much and it should easily pay for itself in better fuel economy before your next oil change.

Stop by Duffy’s Repair Service at 9974 Lickinghole Road, Ashland, Virginia 23005, and we’ll take a look at your air filter for you. Feel free to give us a call at 804.798.5922 to make an appointment.
