Let’s talk about deciphering the auto service menu board. Ashland, Virginia service centers like Duffy’s Repair Service have a board that lists the routine services they provide. But some people don’t know what these services really are unless they ask. Let’s go down a typical list, in alphabetical order, starting with air conditioning service.

Feel free at any time to give Duffy’s Repair Service a call at 804.798.5922 to learn of the many services we offer, or stop by our Ashland, Virginia auto center at 9974 Lickinghole Road 23005.

First remember that all of these services are recommended by vehicle manufacturers. They set how often or at how many miles the service should be done.

Air conditioning service involves purging the old refrigerant and capturing it for proper disposal. Then fresh refrigerant is installed. The fresh refrigerant will lubricate the system and will also help it cool better.

Alignment. Service centers like Duffy’s Repair Service make sure all four wheels are lined up and track with each other. This reduces tire and suspension wear and improves safety and handling.

Battery service. Service centers like Duffy’s Repair Service inspect the battery for corrosion, leaks or damage. Test the battery’s ability to hold a charge. If the battery’s still strong, clean it up. If not, replace it.

Brake service. This could be two things. A brake inspection to see if the brakes are working well mechanically and to see if the pads are still safe. If not, replace the pads and make any repairs that might be in order.

The other thing is to evacuate the brake fluid, clean out the system and replace it with fresh fluid. This is important, but often over looked.

Cabin air filter. The cabin air filter is the filter that cleans the air that comes into the passenger compartment. It works like the filter on your furnace at home. It gets dirty and needs to be changed often.

Cooling system. This is the cooling system for your engine. Replace the old coolant with fresh to protect your radiator and other cooling system components from corrosion.

Differential service. Every vehicle has at least one differential. They don’t require service very often, so people don’t think of them much. The differential transfers power from the drive train to your wheels. Drain the old fluid and add fresh lubricant.

Engine air filter. This filters the air that’s burned in the engine. It also gets dirty and needs to be replaced often.

Fuel filter. This filter cleans the fuel before it gets to the engine. Like the other filters, it too gets clogged and needs to be replaced in order to maintain good flow.

In very simple terms, a fuel injector is a valve that squirts fuel into your SUV engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute in every single fuel-injected car driving down Mechanicsville, Ashland, and Henrico roads.

Most fuel injectors for gas engines are known in the Richmond auto industry as port fuel injectors because they deliver the fuel to a port just outside the cylinder. The fuel pump provides pressure needed to squirt the right amount of fuel into the engine.

A few auto makers have recently introduced gas direct injection systems on some engines. They are now available at some Richmond dealerships. These systems inject the gas directly into the cylinders under very high pressure – many times the pressure of port injection systems.

Although more complicated, direct injection technology promises greater power with improved fuel economy for gas-poor Mechanicsville, Ashland, and Henrico commuters. Virginia motorists can expect to see more of it in the future.

High temperatures under your SUV hood and variations in Richmond gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure.

When injectors are dirty, the fuel doesn’t burn as efficiently resulting in poor fuel economy and loss of power. So it’s important for Ashland drivers keep their fuel injectors clean.

Your Ashland Duffy’s Repair Service service center can perform a fuel system service for you in which the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Proper maintenance of your SUV fuel system means that you will spend less on gas, enjoy strong performance and prevent costly Richmond repair bills down the road.

Today we’re going to talk about power steering service in Ashland. If you took an informal poll around Ashland you’d probably find that most have never heard of power steering service. That’s not surprising. Even though power steering is standard on every vehicle, most people in Ashland aren’t aware that it needs periodic service.

If you’re younger than a certain age, you’ve probably never driven a car or truck without power steering. To get an idea of the difference; if you’ve ever cut a board with a hand saw, you know it’s a lot of work. Using a power saw is easy-peasy by comparison.

Without power steering, your arms have to do all the work to steer the wheels, and that’s hard, especially around downtown Ashland. That’s why old cars had such big steering wheels; to get enough leverage to steer.

Most vehicles in Ashland have a hydraulic power steering system. The serpentine belt from the engine powers a pump. The pump pressurizes the power steering fluid. This actuates a hydraulic cylinder that provides power to help steer.

Some vehicles in Ashland use an electric pump to pressurize the fluid rather than a belt driven pump. We’re also seeing vehicles with electric motors providing the power assist, not using power steering fluid at all. We’ll see a lot more electric systems as more hybrids and electric vehicles hit the market.

At least for now, the vast majority of power steering systems use power steering fluid that needs to be serviced. The fluid needs to be changed for a couple of reasons. For one, it attracts moisture. Water has different hydraulic qualities than power steering fluid, and that makes a difference in steering performance. Water is also corrosive and can damage power steering components. The fluid also just gets dirty and needs to be changed. Removing the old fluid and flushing out the system gets rid of dirt and deposits. The clean, fresh fluid lubricates and provides better corrosion protection.

So ask your Ashland service advisor at Duffy’s Repair Service or check your owner’s manual to see when power steering service is recommended. It’ll extend the life of your power steering components.

Bad air quality while you’re driving around Mechanicsville is nothing to sneeze at. But seriously, more and more vehicles these days come equipped with a cabin air filter. Since they’re fairly new on the scene, a lot of folks don’t know about them yet.

These filters clean the air in the passenger compartment, or cabin, of your car or truck. They do the same job as the furnace filter you have at home. They can filter out particles as small as thee microns. By contrast, a grain of sand is about 200 microns.

So your cabin air filer can clean out dust, pollution, pollen and spores, to keep the air in your car nice and clean. And just like your furnace filter, they need to be replaced when they get dirty. Check your owner’s manual, but they typically need to be replaced at around twelve to fifteen thousand miles.

The filter is usually either under the hood or under the dashboard. Some are a little tricky to get to, so you’ll want to have your Ashland Virginia service center, Duffy’s Repair Service, take care of replacing them.

As we said, many people don’t realize they have a cabin air filter and go to their shop complaining about a funky smell in the ventilation system. It turned out to be a cabin air filter that was long overdue for replacement – really dirty and starting to smell. A quick replacement and they were on their way and smelling fine.

People who are allergy sensitive can really benefit from a cabin air filter, as it keeps allergens to a minimum. If you’re one of them, you’ll want to stay on top of your filter replacement schedule.

Of course if you do a lot of driving in dusty or polluted conditions, you’ll need to change your cabin air filter more often.

These days many people in the Richmond area are really committed to making their cars last a long time. First thing: you’ve got to start with what you’ve got. It’d be ideal if people started with a brand new car, never missed a scheduled service item, paid attention to the severe service maintenance schedule and had regular inspections. But if you’ve had the vehicle for a while, or bought it used, its maintenance history is what it is; and that’s where you start.

Go through the maintenance schedule for your SUV and see what’s been done and when. Have your Ashland service advisor at Duffy’s Repair Service do an inspection and come up with a list of stuff that needs to be done. Review the list and prioritize the work, talk about budget and make a plan to get caught up.

Making a plan is so important. Suppose you go in for an oil change and learn you need your cooling system serviced, a transmission service and are coming up on a timing belt replacement in the next 5,000 miles. You might be pretty overwhelmed.

To make it even more stressful, these are all very important systems that are expensive to repair if there’s a failure. In consultation with your Ashland service advisor, you might decide to take care of the transmission on this visit, set an appointment for the cooling system service next month and get an estimate for the timing belt replacement so you’ll be prepared for it in a few months.

Having a plan for taking care of these important services will set your mind at ease.

A question for our Ashland Virginia motorists: How long have you been enjoying the romantic glow of your check engine light?

Hey, it’s not there to create ambiance; it’s a warning that something’s wrong. When your check engine light comes on get it checked at a capable Ashland Virginia service station.

Many conditions that cause the check engine light to come on affect fuel economy. Some very dramatically.

Always make sure you tighten your gas cap until it clicks. A loose gas cap can cause a false sensor reading that’ll make the check engine light come on.

If your date’s eyes are smoldering in the reflected glow of the check engine light, try to think of all the gas money you’ll save by getting it fixed. Give us a call when you are ready: 804.798.5922

The PCV Valve is a little, inexpensive part that does a big job for Ashland drivers. PCV stands for Positive Crankcase Ventilation.

The crankcase is the bottom area of the engine that holds the oil. When the SUV engine’s running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.

These hot gases are about seventy percent unburned fuel. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause SUV engine corrosion, something we see occasionally at Duffy’s Repair Service. At high speeds on Ashland freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, engine makers simply installed a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, laws mandated that these gases be recycled back into the air intake system to be mixed with fuel and burned in the SUV’s engine.

This is much better for the environment and it saves gas too. (Budget-conscious Ashland drivers take note!) The little valve that controls all this action is the PCV valve. The PCV valve lets gases out of the engine, but won’t let anything back in. Over time, the vented gases will gum up the PCV valve and it won’t work well. That can lead to all of the problems I’ve already described, oil leaks, excessive oil consumption and wasted gas.

Fortunately, it’s very easy to test the PCV Valve at Duffy’s Repair Service and quick and inexpensive to replace. Even so, it’s often overlooked because many Ashland drivers don’t know about it. Check your SUV owner’s manual or ask your Duffy’s Repair Service service advisor. If this is the first time you’ve heard of a PCV valve, you might be in line for a replacement.

There’s another aspect to the PCV system. In order for the valve to work correctly, it needs a little clean air to come in. This is done through a breather tube that gets some filtered air from the engine air filter. Now some vehicles have a small separate air filter for the breather tube called the breather element. That’ll need to be replaced at Duffy’s Repair Service when it gets dirty.

Please ask your friendly Ashland service advisor about your PCV valve. For the price of a couple of burger combo meals in Ashland, you can avoid some very expensive deep engine repairs.

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your car from overheating. There are five main components to the cooling system:

• the radiator
• the radiator cap
• the hoses
• the thermostat and
• the water pump

The water pump’s like the heart of your cooling system, circulating the fluid throughout. It’s a small pump that’s driven by the engine; usually by belt, but sometimes by a chain or gear.

The water pump only operates when the engine’s running. Water pump failure is pretty routine. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Consult your owners’ manual or service technician to see what’s recommended.

Since a water pump either works or it doesn’t, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It’s possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can you tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump – it’s got a problem. If you can see coolant in that area, you’ve got a leak.

Some water pumps are driven off the timing belt. They might be under a plastic cover so you can’t see the water pump. Look for coolant on the driveway. If you see some, have your service center check it out.

Most timing belts need to be changed at 60,000 miles – some longer. It’s a good idea to change your water pump at the same time if it’s one of those that’s driven off the timing belt. To start with, 90% of the work’s already done with the timing belt change. And, if you don’t, and develop a leak later, you’ll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

You can replace your water pump with a brand spankin’ new one or with a rebuilt pump. Rebuilt will save you some money, but ask your technician what he thinks. Don’t feel too bad if your water pump gives out. They will all wear out eventually. Your service technician can get you back on the road and on with your life.

Here’s a travel tip that’ll I’ll bet you didn’t know, and, it might keep you safer…

The average American commuter in Virginia spends two and a half hours daily in their car.

The government says a hundred thousand auto accidents yearly are caused by drivers who fall asleep at the wheel. (Aggressive driving is the number one traffic safety concern.)

So what does this have to do with how your car smells while you’re driving around Virginia?

Well, which scent did you think makes drivers more alert?

Is it:

• A. Strawberry
• B. New Car
• C. Pine
• D. Warm Vanilla Breeze

It’s C. Drivers are more alert and have less fatigue with pine scent in the car, according to AroMetrics.

And, drivers were less angry with overall improved driving performance with strawberry and pine scents.

And you thought they just smelled nice.

Sometimes when we talk about exhaust service in Ashland, we think about exhaust pipes and mufflers. And if you can see smoke, or if it’s too loud. But, exhaust service at a place like Duffy’s Repair Service is really a lot more comprehensive these days.

For example, in the U.S., the federal government mandated catalytic converters for all cars in Ashland in 1976 and on-board emission control computers in 1990. Virginia and federal emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations. Cars sold in Canada follow the same guidelines.

So, exhaust service has really become exhaust and emissions service. High-tech computer-controlled emissions devices are now a big part of that. And because it’s so sophisticated, your vehicle manufacturer recommends having your emission system checked out by a qualified technician, like the ones we have at Duffy’s Repair Service, regularly to make sure everything’s working right – which is usually every six months or 6,000 miles.

If your ‘check engine light’ comes on while you are driving around the Richmond area, especially if it’s flashing, then you need to get your car looked at right away. Chances are it’s an emission related problem. You might have exhaust or emissions trouble if your car is hard to start, runs rough, or if it’s noisy or smoking.

So let’s review the exhaust system. Everything starts with the exhaust manifold. That’s the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe.

The exhaust gaskets help seal the connection with the manifold and other joints along the way. Now, if the manifold is cracked or loose, or a gasket is leaking, then dangerous gases could escape into the passenger compartment, where you ride. Carbon monoxide can be deadly, so it’s important that your exhaust system doesn’t leak.

The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next comes the catalytic converter. This part actually looks like a muffler. It changes chemicals that are dangerous to your health, and to the local Virginia environment, into harmless carbon dioxide and water. Now it doesn’t require any maintenance itself. But eventually they wear out. If it has, you’ll probably find out when your car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car’s sound with different mufflers – which is pretty cool because you can change the look of your car, and the way it sounds.

Rusted or road-damaged mufflers can actually leak and they need to be replaced right away. The exhaust system is attached to the car by a series of hangers and clamps that hold the system in place. And when these hangers come loose or break then hot exhaust components can touch and melt wires, hoses and lines. Just think of the damage a hot curling iron can do – but worse. It’s not good to have that waving around.

And finally, we end at the tailpipe. Appropriate name. This is the final outlet for the exhaust. And one other component is the oxygen sensor. It monitors the oxygen content of the exhaust so the engine-control computer can adjust the fuel-to-air mix to keep the car running right.

We hope this hasn’t been too ‘exhausting’ of a discussion, but these things impact everything from life and death safety due to exhaust leaks, to just fine-tuning the sound of your ride. And talk with your service advisor at Duffy’s Repair Service if you feel you need any of these items inspected on your vehicle, because a quick look can sure save a lot of pain down the road.
