Air Conditioning Service in Farmington

Posted August 28, 2022 12:07 PM



Hey Farmington! Let's talk about one of our MI summertime must-haves: your car A/C. It's real easy for Farmington drivers to take their car's air conditioner for granted. Just push the right buttons and out comes cool, dry, clean air. But your air conditioning system needs attention from time to time to help it keep its cool.

Do you hear loud noises under the hood when you turn on your air conditioner? Do you only get cool air sporadically? If so, it is time to get your air conditioner checked at Darrell's Firestone in Farmington. 

When most Farmington folks hear the words "air conditioning problems." it sends a shiver up their spine. That is because the air conditioning system is fairly complex. It has a lot of parts and when it's broken, it's hard to repair.

What things can Farmington drivers do to prevent air conditioning breakdowns?

A common cause of air conditioning failure is leaks. Water and air can leak into the system. It doesn't work as well with air in it and water can cause rust that leads to damage of the car A/C components. Also, refrigerant, the stuff that makes the air cold, can leak out, reducing the efficiency of the system and making it work harder to cool the air. Periodically evacuating the air conditioning system and recharging it keeps the proper amount of clean refrigerant in the system so it cools better and lasts longer.

Farmington drivers should run their air conditioner regularly, even during a MI winter, so that it lubricates itself and keeps the seals from drying out, which leads to leaks. Your owner's manual will have recommendations for how often to service your air conditioner. Of course, if it's not working right, now is the time to get it checked. The team at Darrell's Firestone in Farmington can inspect and test your air conditioning and offer evacuation and recharge services. This helps you avoid repairs.

Cooling System Components

Posted August 21, 2022 10:31 AM

Today we want to talk about a system in our vehicles – the cooling system. It's one of those things that Farmington auto owners don't give much thought to until it fails and then they're stranded by the side of a road in MI.

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 Farmington drivers take care of their cooling systems, they can keep working for the life of their car.

Here at Darrell's Firestone in Farmington, 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, radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.

It sounds complicated, but we Farmington residents don't have to be experts – we can leave that to our friendly and knowledgeable service advisor at Darrell's Firestone. But, having an overview will help us remember how to take care of your car's cooling system.

Most Farmington folks would be surprised to know that burning fuel in your engine produces up to 4,500 degrees F/2,500 degrees C 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 vehicle 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 cash on replacing the belts and water pump is much less than the cost of repairing the extremely massive damage that can be done when an engine seizes.

There's another little known but important 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 is enough to 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.

The team at Darrell's Firestone can check your cooling system and make any necessary adjustments or repairs. Give us a call.

Put on the Brakes: Brake Service at Darrell's Firestone

Posted August 14, 2022 10:01 AM

When it comes to preventive maintenance and vehicle care, most Farmington drivers know how important it is to check their brakes. But brakes are more than just brake pads and shoes. There are a lot of components in the brake system, and they all need to be in good working order.

The pads and shoes are known as the friction materials in the brake system. They push together, providing friction which stops the vehicle. It's no wonder they have to be checked regularly for wear, and brake pads and shoes need to be replaced periodically.

Brake pads/shoes gradually wear out, but that doesn't mean your braking gradually becomes less effective. The pads are engineered so that they maintain good braking until they wear too thin to provide adequate friction. At this point, they need to be replaced.

But your braking system also has mechanical parts. These pistons and springs can also gradually wear out or get gummed up by oil, dirt and other road spatter. A brake inspection at Darrell's Firestone in Farmington  includes a check of these parts as well as the pads and shoes. Your friendly and knowledgeable pros at Darrell's Firestone can then advise you of any parts that need cleaning or replacement.

The fluid component to the brake system needs a regular check-up at Darrell's Firestone as well. The brake fluid cools and protects your brake system. Protective additives are gradually depleted by the operation of the brake system, and moisture buildup inside the fluid can diminish its effectiveness. When you have your brakes serviced at Darrell's Firestone in Farmington, the fluid should be checked and, if needed, replaced, which will clean out water, debris and dirt.

It is important to remember that your brake system also includes your tires. No matter how well your brake system is performing, if your vehicle tires are worn, you won't get good stopping power. Traction is the power of your tires gripping to the roadway. Traction is always better on tires with a good tread. Good traction translates to good braking.

This is particularly important on wet Farmington roads. A good tire will give you good braking on either wet or dry MI roads. But stopping distance increases dramatically when worn tires meet wet roads. Tread on a tire acts to channel away water as the vehicle passes over the wet road, improving  contact between the tire's surface and the road; that maintains traction. But the thinner the tread, the less effective the water channels become, and water can get between the tire and the roadway, reducing friction. A loss of friction means a longer stopping distance and possibly the loss of control.

Braking depends on two things: the weight of your vehicle and the speed of the vehicle. The heavier the vehicle or the faster the vehicle, the more braking power it requires. Thus, brake systems vary from vehicle to vehicle. For example, a pickup that is designed for heavy loads has a more powerful braking system than a compact car. Sports cars also have higher-grade braking systems than minivans.

Regardless of what kind of car you drive in Farmington, it is always good auto advice to keep your brake system in good repair, and that means ALL of your brake system. Just one more way to keep your travels accident- and worry-free.

Out with the Old (Vehicle Parts that Wear Out)

Posted August 7, 2022 12:41 PM

Some drivers don't pay any attention to their vehicles until something breaks.  Others take them into their service repair facility for maintenance even before a problem develops.  Still, even if you fit into the second group, there are some parts on a vehicle that will simply wear out over time.

Your vehicle has gaskets in several places.  They use a flexible material to seal the gaps between metal parts that fit together. After time, that material shrinks or gets brittle and fails.  Eventually, after time, you will have to get gaskets replaced.

Same goes for belts.  Your engine has belts that help take the mechanical energy of the engine to drive other parts such as the generator and air conditioner.  Heat and age will eventually cause these belts to wear out or break, so you'll need new ones at some point.

You'll also find yourself buying brake pads.  As much as you may try to go easy on them, brake pads work by wearing off a little bit of them each time they help you stop your vehicle.  Do a lot of stop-and-go driving and you'll hasten the process.

No battery lasts forever, and your vehicle's battery is no exception.  It can only charge and discharge electricity so many times.  Count on getting no more than 4 or 5 years out of a battery, fewer if you live in a very hot spot.

Other parts that don't age well? Tires.  They can have plenty of tread left on them, but rubber gets old and loses its flexibility. Tires have their date of manufacturer stamped on them for a reason.

Finally, your muffler is being subject to moisture from inside and out: inside because of moisture-containing exhaust and outside from the elements outdoors. Stainless steel or other alloys will last longer, but after a while, either the moisture or constant pounding from vibrations will take their toll.

That's why it's important to maintain every part on your vehicle. You can't wave a magic wand and make everything last forever, but take care of your vehicle and it'll take care of you.
