Automotive Tips from McPherson Automotive: Air Conditioning ? Common Problem

Your auto air conditioning system cools and conditions the air in your passenger compartment when you are driving around Du Quoin. It also removes moisture from the air to keep your windows from fogging up.

A common A/C problem for Du Quoin drivers that visit McPherson Automotive is contaminated refrigerant (the gas that cools the air). The inside of the A/C hoses deteriorates over time and tiny fragments of rubber clog passages. This makes the system less efficient and overworks various components.

Leaks can develop at seals and gaskets and may reduce the amount of refrigerant, causing the system to work too hard to compensate. Dirty components can have the same consequences.

Ask your McPherson Automotive service advisor for an air conditioning system inspection to make sure everything is up to spec.

Bouncy Bouncy ? Are My Shocks Bad?

When Du Quoin drivers think about preventive maintenance, what usually comes to mind is oil, fluids and brakes. We don't generally think about our shocks or struts, but these auto parts keep our tires on the road.

Du Quoin drivers don't think about shocks as often as oil changes because shocks and struts last a long time and wear out slowly. They don't need to be checked as often as our brake pads or air filters. By the time your shocks have 50,000 miles (80,000 kilometers) on them, their performance will have noticeable degraded. If you want to restore the handling and ride designed for your vehicle, try replacing your shocks and struts.

Of course, if you drive off-road around Du Quoin, carry heavy loads, tow a trailer or put in a lot of mileage on poor driving surfaces, your shocks or struts will wear out more quickly. You'll need to replace them more often or upgrade to better shocks.

Your suspension system uses springs and shocks to absorb the “shocks” and vibrations of driving over road surfaces. Springs support the vehicle's weight, suspending it above the axles so the body of the vehicle is protected from most of the bumps on the road. Shocks control the bounciness of the springs by moderating rebound. They also push your tires down onto the road's surface, maximizing traction. Without shocks, your wheels would bounce over bumps and lift against curbs and corners. Shocks are important to the safe handling of your vehicle as well as a comfortable ride. Struts are a combination shock and spring in one unit.

Worn shocks result in lowered vehicle handling performance. If your vehicle “squirms” around corners or gets “floaty” over bumps, then you need to check your shocks. If the rear end of your vehicle squats while accelerating, the front end dips while braking, or one corner sags, you probably need new shocks.

If you're unsure whether you need new shocks, or if you're considering upgrading to a higher quality shock, then consult your friendly and knowledgeable McPherson Automotive service advisor. He or she can give you advice on the condition of your shocks and how to match your driving needs to the quality of your shocks.

At McPherson Automotive we know good vehicle care is essential to the safety, performance and efficiency of your vehicle. It can improve the comfort of your ride as well.

Low Power Mystery (Ignition Coil Service)

It's no fun when your vehicle just doesn't run the way it used to.   You may notice (especially in cold weather) the engine won't start easily or when it does start, it doesn't run smoothly. It may not have much power at all. You also may have had to stop at the gas station more often, a sign your fuel economy isn't what it used to be. 

There could be a few different things that cause those symptoms, but one culprit could be a bad ignition coil. The coil takes the voltage from your battery and multiplies it before that power is sent over to a spark plug. That allows the plug to fire off a good jolt of electricity that ignites the fuel in your cylinder and powers the engine. 

There's usually one ignition coil for each cylinder (or sometimes for a pair of cylinders). If only one of them is not pushing out enough electricity, it can cause big trouble with your engine performance.  Other signs of a bad ignition coil include engine backfire, an oil leak and your Check Engine light coming on.   When that light comes on and you have some of those other signs, you need to have your repair facility check things out fairly soon because you may be damaging your engine and wind up with a far more expensive repair.

A technician will check for a computer code to pinpoint which cylinder is having the problem.  Using other diagnostics, the technician can rule out other components that might be causing the engine to misfire.  Ignition coils usually last 100,000 miles/160,000 km, but other engine conditions can cause them to fail before then. 

Your service advisor may suggest getting all your coils replaced even though only one is malfunctioning. That's probably a good idea in a higher mileage vehicle since the other coils may be close to failure, too. It's also wise to do that if your vehicle's coils are located in a hard-to-reach spot so you likely won't have to spend the money for that labor again when another one fails.

Right or Left? McPherson Automotive Power Steering Service

Have you ever driven a vehicle without power steering? If you have, then you probably appreciate how much easier it is to drive today's modern vehicles. Before power steering, all of the force to turn a vehicle had to come from the driver's arms. That's why old cars had such large steering wheels: they needed plenty of leverage to steer. There were some Du Quoin folks who had difficulty driving because they just weren't strong enough.

Power steering is now standard on all vehicles, but there are several ways that power can be delivered. Most vehicles use a hydraulic power steering system system. In this system, a serpentine belt from the engine powers a pump that pressurizes the power steering fluid. The pressure activates hydraulics that provides steering power.

Other vehicles use an electric pump to pressurize the power steering fluid rather than the belt-driven pump. Some newer vehicles actually have electric motors that provide steering power and don't use steering fluid at all, especially in the increasingly popular hybrid and electric vehicles.

Du Quoin drivers who own a vehicle that uses power steering fluid need to have it changed regularly. Over time, moisture accumulates in the power steering fluid, which affects steering performance and can corrode steering components. Dirt and other contaminants can also accumulate in the power steering fluid, which will also negatively affect steering performance. A good power steering service at McPherson Automotive in Du Quoin will flush out the old fluid and get rid of dirt and other deposits in the system. Clean fluid will then be added. Fresh fluid provides lubricants that help protect the steering system as well as prevent corrosion.

For recommendations on how often your power steering fluid should be replaced, consult your owner's manual. It varies by vehicle model and manufacturer. For more auto advice on steering fluid changes—and other preventive maintenance—you can talk with your service advisor at McPherson Automotive. You may need to change your fluid more often depending on the driving and weather conditions in your area.

Du Quoin drivers who believe in good vehicle care will add power steering service to their preventive maintenance schedule. This will prevent damage to your steering system and extend its working life. The old days of double-handed cranking on a huge steering wheel may be over, but our new comfort and convenience are not maintenance-free. Do yourself and your vehicle a favor. Keep the power steering fluid clean.
