Air Conditioning Maintenance at Darrell's Firestone in Farmington

Warm weather or cold, Farmington drivers still need to think about their vehicle's air conditioning. Most Farmington people don't service their air conditioning until after it fails. At Darrell's Firestone, we can advise you on your vehicle manufacturers preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on.

Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the vehicle's air conditioning system allow the refrigerant to escape and the system can't cool the air as well. We see that a lot at Darrell's Firestone in Farmington.

The refrigerant also contains oil that lubricates air conditioning components and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all Farmington vehicle owners know that air conditioning repairs can be costly. At Darrell's Firestone, we recommended that the air conditioner be run regularly, even during winter months, to keep the parts and seals lubricated.

Farmington drivers need to be aware that there's one more thing that isn't directly related to air conditioning service but does impact the quality of the air in your vehicle. And that's your cabin air filter. This filter cleans dust, pollen, pollution and other impurities in the air that come from the heater and air conditioner. The cabin air filter needs to be replaced when it's dirty. If you don't, it'll start to smell. Not all vehicles have one, so ask your Darrell's Firestone service advisor to check your cabin air filter at the same time they're doing your air conditioning service.

Avoiding Exhaustion (EGR Valve Replacement)

No, ERG isn’t the sound a pirate makes.  It’s a part in your vehicle that recirculates exhaust gas to reduce certain gases and pollutants in the atmosphere.  In fact, ERG stands for “Exhaust Gas Recirculation.”

One gas our vehicles may make when they burn fuel is nitric oxide, which can play a big role in creating smog and acid rain.  It’s better for our planet if our vehicles aren’t spewing that into the air.  

One inventive way of reducing it is by taking the exhaust and channeling it back to the vehicle’s air intake system. When it travels through the engine again, its composition is changed, and it comes out cleaner.  It also helps the engine be more efficient.

The EGR valve can fail after a while, and some signs you may notice are the engine is miss firing, it may suddenly lose power or your Check Engine light may come on.  You may also see your fuel economy decrease or hear your engine knock. A bad EGR valve can also make your vehicle fail an emissions test.

There are several different types, including newer ones that are electronically controlled rather than working on vacuum pressure.  They are found in newer gasoline and diesel vehicles. If you notice any of the symptoms of a failing EGR valve, bring your vehicle in so a technician can check to see if your EGR is still up to its “exhausting” job.

Combustion Choreography: Timing Belt Replacement at Darrell's Firestone in Farmington

Have you ever seen a ballet performance? Have you wondered how all of those dancers manage to travel all over the stage jumping and twirling and never crash into each other? That's the job of a choreographer.

Our auto engines are also highly choreographed. Pistons travel up and down inside cylinders. Valves at the tops of the cylinders open to let air and fuel in or exhaust out. These valves have to open and close at precisely the right time or the engine will run poorly if at all. The movement of the valves and pistons must be in harmony with each other. This choreography is the job of the timing belt or timing chain.

Timing belts, or chains, rotate the shafts that control the opening and closing of the valves. Timing chains are metal and durable enough that they may never need to be replaced.

Most vehicles, however, use a timing belt. Timing belts are tough and flexible, and considering the work they do, they last a long time for Farmington auto owners . But they do wear out. If they break, the consequences for Farmington drivers can spell disaster.

No matter what kind of engine you have, a broken timing belt will cause the engine to shut down or will lead to major engine damage. But in some engines, the valves protrude down into the cylinders enough that if the timing belt breaks, the pistons can smash the valves, bending or breaking them. If the engine is spinning fast enough, the broken parts can then shred the cylinder head. This adds to thousands of dollars of engine damage.

The only way the damage can be avoided by Farmington auto owners is by replacing the timing belt on schedule. Most vehicle manufacturers recommend replacing the timing belt at 60,000 miles (100,000 kilometers), but others can go as long as 90,000 or 100,000 miles (145,000 to 160,000 kilometers). Check the schedule for preventive maintenance in your owner's manual. If you're due or overdue for a timing belt replacement, don't put it off. Get it done now at Darrell's Firestone in Farmington.

Your friendly and knowledgeable Darrell's Firestone technicians probably aren't great dancers, but they can offer you some great auto advice on how to keep your engine properly choreographed. Don't hesitate to consult them about replacing your timing belt or any other car care concerns you may have.

Bump in the Road (Alignment)

There's something you can do that helps your tires last longer, wear more evenly and your vehicle handle better.  "Sign me up," you say! Wondering what that is? It's aligning your wheels, and it will literally point you in the right direction when it comes to a better and safer driving experience.

When your vehicle was designed, the engineers made sure your tires were all pointing the same way by designing the suspension to make optimal contact with the road. That way the ride is smooth, you don't feel vibrations or shimmying and your vehicle travels in a straight line, without pulling to one side or the other.

Unfortunately, your vehicle is not brand new; time and distance take their toll.  After hitting countless bumps, potholes, or the occasional curb, your suspension gets knocked a little out of kilter.  Those precise angles the engineers planned on for your vehicle? They get out of whack

Uneven or premature tire wear is one of the first signs your alignment may be off.  If you are driving straight and your steering wheel isn't pointing straight, that's another indication alignment might need checking. Tire squealing can also be a clue.

When you bring your vehicle in for an alignment, we use equipment designed to measure the tilts and angles of your suspension's parts.  The technician will also check to see if any of the vehicle's suspension components are worn or broken.  We will also check your steering angle sensor to make sure it's set properly. 

The process is different for vehicles that are front-wheel drive, rear-wheel drive, all-wheel drive, or 4-wheel drive. 

After your alignment, your tires should wear more evenly, your steering should be straight and your wheels vibration-free.  If it's been a while since you've had your vehicle aligned, bring it in and we'll check it.  Usually, your alignment will be a little off after one or two years of driving, and it's wise to follow your vehicle manufacturer's recommendation for how often your model should be checked.

When Your Tires are Tired (Tire Replacement)

Tires are so reliable these days that few drivers pay much attention to them.  But tires wear out.  They have a tough job since they are the only point of contact between your vehicle and the road.  They have to get your vehicle going from a stop, keep it going, make sure it is headed in the direction you want it to go, and –importantly – slow and stop it.  

The only time many drivers think about their tires is when there's a problem, such as a flat.  Or, they may lose control when they find their vehicle isn't stopping or steering like it used to.  One major safety organization estimates that 1 out of every 11 crashes is related to a tire issue.  

Many of those problems are caused by tire tread wearing out.  The rubber is worn off by friction after hours and hours on roads.  The sidewalls can also be damaged by your tires hitting curbs, potholes, or other debris. Plus, rubber ages as time passes.  We recommend you let us inspect your tires periodically so we can spot potential problems before it's too late.  

When it's time for you to replace your tires, it's important to know which type is right for your driving habits and what environments your tires usually encounter.  The most common tires are called all-season. As the name says, they are pretty good in every season and their tread lasts a long time.  In other words, they're good all-purpose, all-around tires.

Another option is a performance all-season tire, which has a little more grip but won't last as long. Then there are ultra-high-performance tires (UHP) which have wonderful grip and handling but an even shorter lifespan. They also aren't the greatest in slippery conditions.

For those who live in more extreme climates, especially where there is a lot of snow, winter tires are definitely worth considering because their performance in cold, snowy conditions can make a huge difference in traction, improving steering, and stopping.  Some places require winter tires during certain periods of winter.

Don't underestimate how much of a difference tires can make on your vehicle.  Sure, you probably don't pay much attention to them, but they are one of the most important investments you can make, and they can pay valuable dividends when you need them to come through for you.
