Sound of Silence

Sound of Silence

The job of a muffler is to keep your vehicle quiet. There is a lot involved for a piece of equipment that doesn’t look too intricate. It silences the noise of your car in these ways: Changes the pressure pulses Dampens the pressure pulses Absorbs the pressure pulses The noise is measured in decibels and the muffler dissipates the level of sound. There are two types of mufflers; direct-fit or universal. A direct-fit muffler doesn’t require modifications. A repair shop just has to line it up and bolt it on. They are, however, not readily available for all vehicles. A universal muffler is easy to find and usually requires some modifications. This is done by lengthening or shortening pipes or even replacing them. New hangers are a must to keep the new equipment from rattling. Thankfully these modifications are not difficult or expensive; they just take more time. If you are replacing a direct-fit muffler with a universal muffler, don’t expect it to muffle the ... read more

How's The Air In There?

How's The Air In There?

Hey, Phoenix drivers, did you know you have a great little device called the cabin air filter and its function is to protect drivers and their passengers from contaminants such as pollen, mold spores, dust and other small and annoying particles? The cabin air filter is located on the passenger side of the vehicle and is most often, but not always tucked behind the dash around the glove compartment area (don’t you wonder why we still call it glove compartment? I wonder how many actually contain gloves.). Whenever you turn on your defroster, air conditioning or heater it captures the debris so it doesn’t get into the cab of your vehicle. It is a very busy part and needs to be replaced at least once a year. If you or a passenger has severe allergies you may want to get it replaced more often. A clean cabin filter also helps prolong the life of your vehicle’s heating and air-conditioning system because it keeps debris and corrosion away from the evaporator core. A ... read more

Late Model Cars Can Be A Challenge To Your Car’s Battery Life

Late Model Cars Can Be A Challenge To Your Car’s Battery Life

Today’s newer models have a lot of “bells and whistles” and this puts a lot of demand on battery charging systems. We all know that climates with excessive heat take their toll, such as our Arizona temperatures. Our hot weather causes the electrolyte inside the battery to dry out. The popular maintenance free type battery has a sealed top so it doesn’t even allow water to be added, so its life expectancy in Arizona is low. Ideally, the battery should be at full charge. When it starts to lose its charge, sulfate builds up on the plates. As it sits, the sulfate takes hold and is difficult to loosen once the battery is recharged. Sadly, it then becomes more difficult to “recharge” and will quit all together. To keep the “bells and whistles” going strong in modern cars, they need to draw current from your car’s battery even when it is not running. Here is an example; you use your key fob to gain entry to your vehicle as it is ... read more

Dealing With Brake Dust

Dealing With Brake Dust

I’m sure most of us have experienced this…you drive through an automatic car wash and when you get home you notice the clean shine of your entire vehicle…until you look down at the wheels. What is that grime on the wheels? That is brake dust… metallic particles, carbon fibers and adhesive residue from your vehicle’s brake pads that attaches to your wheels. To keep it from building up it should be removed weekly as it essentially bakes on to the surface of alloy wheels. It is recommended that you wash the wheels when they are cool to avoid streaking, discoloration and pitting. The adhesive residue in the dust causes it to bond firmly with the wheels and since they are most often acidic it starts a corrosion process. The metal filings in the dust usually oxidize with the metal of the rims causing galvanic corrosion to occur. If you are removing the dust yourself be careful not to inhale the dust or the vapor from cleaning products especially designe ... read more
