Cabin Air Filter From Darrell's Firestone

Here is a questions for Farmington drivers: What is a cabin air filter?

Is it:

1. A filter for a house in the middle of the woods?
2. A fresh, piney scent?
3. A filter for the passenger compartment of your car?

Clever you, it's 3.

A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out dust, pollen, spores, bacteria, pollutants, sparrows, exhaust gas and odors.

These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.

Now not all vehicles in the Farmington area have cabin filters. They are fairly new on the scene in MI. About 40 percent of new vehicles come with cabin air filters, but the number is growing every year.

Cabin air filters can make for a very nice driving environment for Farmington. Your car can be a haven during MI allergy season with very little dust and pollen getting into the cabin. However, like all filters, your cabin air filter eventually gets clogged. When this happens, your heating and air conditioning flow can become restricted. The filter can even get kind of smelly.

Check your vehicle's owner's manual for recommended replacement intervals. Often, the owner's manual forgets about the cabin air filter, so ask your friendly and knowledgeable Darrell's Firestone service advisor for a recommendation. It's usually every year or 12,000 miles/19,000 kilometers. Change it sooner if you drive in dusty Farmington conditions or if you start to notice an odor from your ventilation system.

So, Farmington drivers, keep your cabin air filter clean. It may not help with your brother-in-law in the backseat, but it will make your driving experience more enjoyable.

Oil's Well That Ends Well (Oil Change Grades and Weight)

Changing your oil regularly is one of the most important things you can do to keep your vehicle running well.  And knowing the right type of oil to use is also very important. 

Engine oil is classified by weight, but it doesn't refer to how much the oil would weigh if you put it on a scale.  It refers to viscosity, or how easily the oil flows through the engine.  Most engines operate normally at around 210°F/99°C.  The viscosity, or weight, is assigned a number by how well it flows at that temperature.  The lower the number, the more freely it flows. 

Most vehicle engines use what's called a multigrade oil which behaves differently in different temperatures. Multigrade oils have a "W" in their viscosity number that you may have seen on a bottle of oil, something like 5W30.  The W stands for winter and shows how freely it flows in colder temperatures.

That means a 5W30 oil will behave like a 5 weight oil in lower temperatures (less viscous or thinner) and a 30 weight oil in warmer temperatures (more viscous or thicker).  That's important on a cold day because the oil needs to behave like a thinner oil when you start your engine since it need to lubricate engine components immediately to protect the metal components. Then as the engine warms up, it behaves like a thicker oil to prevent friction among those parts.  Pretty neat trick, right?

The type of oil you use can differ depending on what type of climate you operate your vehicle in and how your vehicle is used (carrying big loads, towing, etc.). Your owner's manual contains several different recommendations based on these factors.  Your service advisor can recommend the right oil for your needs.  Like Shakespeare said, "Oil's well that ends well."

Automotive Tips from Darrell's Firestone: Making Your A/C System Last Longer

Farmington drivers know that if their air conditioning system isn’t making cool air like it used to, there is a problem. It may be as simple as adding more of the right kind of refrigerant.

Your A/C requires special compressor oil, which circulates through the system along with the refrigerant, to lubricate and protect expensive components and keep seals and gaskets from drying out. If refrigerant has leaked out – so has the compressor oil. This oil needs to be replenished whenever refrigerant is added.

An air conditioning inspection at Darrell's Firestone will uncover any potential problems and identify any necessary repairs needed to get Farmington drivers on the road to cool air once again.

Give us a call.

Keys to a Long Lasting Vehicle

We live in a disposable society. Everything from elaborate packaging to our clothing. Even cell phones are disposable. When replacement is cheaper than repair, the term "built to last" goes by the wayside. An exception is our vehicles. They're still a very big investment and Farmington drivers want to make them last as long as possible.  We also want to make keeping them running as cheap as possible. When talking vehicles, it's all about preventive maintenance. There is an old saying that says, "A stitch in time saves nine," and that is really true when it comes to taking care of your vehicle. A great example is coolant service in Farmington.

Your coolant not only protects your engine from overheating and freezing, it must also protect cooling system components from corrosion. Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. That's why you need to have your cooling system serviced on a regular schedule.

The same is true for your power steering system, brake fluid, air conditioning system, differential and transmission. And of course, Farmington vehicle owners shouldn't forget those oil changes right on schedule. Skipping even one change can start the build up of harmful oil sludge.

Our engines are full of gaskets and seals. Fresh fluids condition those gaskets and seals to keep them from drying out and leaking. Automotive fluids contain additives that help clean and lubricate the various systems they protect. Over time, the additives are used up and the fluid just does not provide the protection it did when it was fresh. And don't forget the mechanical systems. Changing brake pads before they are worn to the point that they cause damage to rotors is a great way to keep your operating costs down.

Replacing serpentine belts and timing belts on schedule is much cheaper for Farmington drivers than repairing the damage that can be caused by failure. Also, air filters, fuel filters, PCV valves and batteries are all important. Regular wheel alignments, tire rotation and balancing will make your tires last longer. And don't forget to replace your shocks and struts when they wear out. Your fuel system needs regular cleaning to keep running well, prevent mechanical damage and improve fuel economy.

Now this is a lot to remember for Farmington drivers - too much, really. But it is your Farmington automotive technician's job to keep on top of this stuff. At Darrell's Firestone we can tell you what your manufacturer recommends and help you with a plan to take care of it. We can advise you about which  maintenance schedule you should use - the regular schedule or the severe service schedule - depending on the kind of driving you do. We also know the right fluids for your vehicle and may even suggest higher mileage formulations for your older vehicle.

Bottom line - take care of this stuff on schedule and you will reduce operating costs, prevent damage and maintain your warranty coverage.

Of course, you want your vehicle to look as good as it runs. Regular washing will prevent rust and protect your finish. Take advantage of cleaners, waxes and protectants for your interior and tires. Your vehicle will look great and you'll be proud to drive it longer.

Most of us in Farmington can't afford to throw away our car when it breaks down. By budgeting for regular preventive maintenance, we can prevent many inconvenient - and expensive - problems down the road, and can keep driving "old faithful" for years to come.

The Flat Fix that Fits (Tire Repairs)

Can you think of anyone who likes getting a flat tire?  Of course not.  But when one of your tires winds up with a flat or leak, whether it be from things like hitting a curb, running over a nail or picking up a sharp stone, it's time to have someone who knows what they're doing take care of it.

If you're thinking you'd like to avoid having to buy a new tire, you wonder if a patch or plug will suffice.  It depends where the puncture is and how big the hole is.  Most tire experts will say if the hole in the tire is less than ¼ of an inch or 6 mm, a patch can work.  But a patch likely won't work if the compromised part of the tire is on its shoulder or sidewall.

Here's why.  The shoulder of a tire is the part between the sidewall and tread and it's usually rounded.  It's under a lot of pressure, more than even the sidewalls. And because of that curved shape, it's hard to get a patch or plug to hold.

The sidewall is the side of the tire.  Sidewalls flex a lot when you drive, and the strain can cause a patch or plug to loosen up.  A weak spot in a sidewall is much more likely to fail and cause a blowout.  So if you have damage in the sidewall or shoulder, that tire is a good candidate for replacement, not repair.

If you have a cut or gash in your tire, it's possible the cords that strengthen your tire have also been cut.  That weak spot can spell trouble, and this type of damage usually means you should get a new one.

Your service advisor can tell you what the appropriate action is to take when you have tire damage.  You may be able to get good results with a patch, or you may have to replace one or more tires.  Your safety is riding on them.
