Many people in MI are keeping their vehicles longer. The economy has influenced that, but the fact that modern vehicles are more durable and reliable means that owning a high mileage vehicle doesn't have to be a painful experience.

Local car owners in Farmington with over 100,000 miles on their vehicles often ask which service intervals they should follow. Let's start with the special needs of the older vehicle...

The reality is that time and mileage will take its toll. The engine and transmission will have more sludge. The fuel, steering and brake systems will have gum and varnish built up. There'll be more dirt and contaminants in the fuel tank. Corrosion and deposits in the cooling system. And seals and gaskets will start to dry out.

All of this, plus normal wear and tear, means that the engine might not be as strong as new, so it just has to work harder to get the job done.

So we need to compensate. Consider high-mileage formulations for oil changes, transmission service, etc. These special formulations contain additives that condition the seals and gaskets to prevent leaks. They also have more detergents to clean sludge and other deposits. They cost a bit more, but they're worth it.

In general, if an auto service was recommended every 15,000 miles when the car was new, you should continue to get the service done every 15,000 miles.

Talk with your Farmington service advisor at Darrell's Firestone about the condition of your engine. See if he thinks you should adjust your auto service intervals for oil changes or other auto maintenance to account for the older engine working harder.

Expect the oil filter to get dirty faster. Same goes for the fuel filter. And some leaks are to be expected so you need to keep a closer eye on fluid levels.

If anything, following recommended service intervals for your vehicle is more important in a higher mileage vehicle. Skipping oil changes or other services can lead to problems much more quickly than with a newer vehicle.

So, have your Farmington auto service advisor at Darrell's Firestone help you with an assessment of your older car or truck. If you haven't gotten around to a fuel system cleaning, or replacing power steering or brake fluid, a differential service or transmission service – it's time to start taking care of those things. It'll help keep you on the road for many more happy miles.

Cabin Air Filter and Engine Air Filter: What’s the Difference?

You may have heard someone say they just got the air filter replaced in their vehicle.  But did you know your vehicle has two different major air filters and they both perform quite different—but very important—duties?

Today’s vehicles have a cabin air filter, and an engine air filter.  The engine air filter cleans the air that enters your engine so it can run better, and so contaminants don’t foul vital parts.  While the cabin air filter keeps the air inside the vehicle’s cabin clean, the place where you and your passengers sit.  

It is important that you have each of these types of filters changed at regular intervals, or earlier if either shows signs that they’re contaminated. Your vehicle’s owner’s manual often will recommend how long that interval should be.

First, let’s look at the engine air filter. Your vehicle’s manufacturer will offer guidelines on how often you should change the engine air filter as a matter of routine, by mileage or time interval.  

If you see signs of engine air contamination, such as misfiring, an illuminated check engine light, smoke coming out of your tailpipe, or loss of power, you may need to have the engine air filter replaced sooner.  

Next, the cabin air filter.  Again, the vehicle manufacturer will suggest how often you should replace it. But if you notice excess dust in the cabin, on the dash, console or seats, a bad smell in the cabin, or lower air flow out the heating and cooling ducts, you should have us check to see if your cabin air filter needs replacing. In either case, we’ll make sure we replace your air filters - either engine or cabin - with ones that are right for your vehicle.

Water Pump

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

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

The water pump's like the heart of your cooling system, circulating the fluid throughout your vehicle. 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. We see it often at Darrell's Firestone. Some start failing at around 40,000 miles/64,000 km, but most fail by 100,000 miles/160,000 km. Consult your owner's manual or friendly and knowledgeable service advisor at Darrell's Firestone 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 Farmington drivers 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 Darrell's Firestone check it out.

Most timing belts need to be changed at 60,000 miles/97,000 km – 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.

Darrell's Firestone can replace a failed water pump with a brand spankin' new one or with a rebuilt pump. Rebuilt will save you some money, but ask your service advisor at Darrell's Firestone what he thinks. Don't feel too bad if your water pump gives out. They will all wear out eventually. We can get you back on the road and on with your life.

Chilly Warning (Diagnosing a Noise in Cold Vehicle)

When the weather gets colder, sometimes the noises your vehicle makes will change.  For example, you may notice a whining sound when you get going in the morning.  It may go away when the vehicle warms up, but it's best not to ignore that sound because it could be a warning of worse things to come.

Colder temperatures cause different components to behave differently.  Let's take a look at a few of them.  First, the fluids in your vehicle.  Cold temperatures can make them behave a little differently, such as engine oil, transmission fluid and power steering fluid. Those characteristics could change if the fluids are older and full of contaminants.

Belts also can create a whining noise when cold.  Since they turn pulleys that move other things, several factors can create issues.  Increased friction can change proper tensions on belts.  Plus, belts change as they age and may crack, get loose or develop a glazed surface. Belts and pulleys also must be aligned properly to work the way they're designed to.

As you can imagine, it's easier for a technician to diagnose a noise if the vehicle is making it.  And if a vehicle only makes a noise when it's cold, that sound may be gone by the time the vehicle makes it to the repair facility.  That means a driver may have to consider dropping off the vehicle the night before so the technician can be the first to start it the following morning.  Most service facilities can accommodate that with either a drop-off box or other arrangement.  Heed your vehicle's warning when you start to hear unusual noises.  That's a cool idea you should be able to easily warm up to.
