FAQ

This page provides answers to some of the most frequently asked questions about vehicle repair and service. We've thrown in some of our favorite tips and recommendations, too. Please call us or consult our Contact Us page for answers to your specific questions. We are happy to assist you!

  • Tires

    • How much air should I put in my tires?

      Proper inflation is the single most important part of tire care. Check or adjust inflation every few months and always use the inflation recommended by the vehicle manufacturer. Checking air pressure should be standard procedure on any routine visit to your vehicle service center for oil services, tire rotations, or general maintenance and repair. For do-it-yourselfers you can find this information in your owner's manual, posted on the edge of the driver's door, on a door post, in the center console, or on the inside of the glovebox door. Be sure to check inflation when tires are COLD: when the vehicle has been driven less than a mile or one hour or more after driving. Use a good quality tire gauge. And don't forget to check the spare!

    • How important is wheel alignment?

      It is very important! Having your wheels aligned helps in prolonging the life of your tires. Research indicates that the average car is driven about 12,000 miles per year. A car with toe alignment just 0.34 degrees (Just 0.17 inches) out of specification has dragged its tires sideways.

    • What should I do if I notice a vibration?

      Vibration is an indication that your car has a problem. You should have your tires, steering system and suspension system checked to help determine the cause and correction of the vibration. If the problem is not corrected, the vibration could cause excessive tire and suspension wear.

    • An illuminated light on my dash shows that I have a low tire. Can I just put air in it?

      In many cases correcting the air pressure in your tires will extinguish the Tire Pressure Monitoring System (TPMS) warning light. Often seasonal temperature drops will lower tire air pressure a few pounds (a good case for Nitrogen – see 11 above) and trigger the TPMS warning light. In all cases where one or two particular tires are significantly lower than the others, or lower than the factory recommended pressure, a trained tire technician should examine the tire to determine the cause and examine the casing for signs of over stress. Some TPMS systems require special tools to access the vehicle computer. Advanced level tire technicians are trained and equipped for this technology.

    • How often should I rotate my tires?

      Your tires should be rotated every other oil change, or every 6000 miles. Neglecting to rotate tires is a major cause of premature tire wear.

  • Vehicle Maintenance

    • I have 100,000 mile spark plugs in my car. When will I need a tune-up?

      In the traditional sense there is no such thing as a tune-up anymore. Carburetors and distributors with their myriad of parts destined to failure have been replaced with electronic injectors and electronic ignition systems. There is virtually little to wear out. Aging Ignition wires and spark plugs may continue to function for 100,000 miles but not optimally. The car manufacturer’s boastful claim of 100,000 between tune-ups has little grounding in common sense, and is mostly a marketing ploy. At the price of gasoline these days even a three percent decrease in fuel efficiency is expensive, not to mention ecologically unfriendly. A fresh set of spark plugs any time over 50,000 miles will normally make a noticeable difference.

    • What are all of the chemicals and fluid flushes for? Are they really necessary?

      Protecting the vital wear points of your vehicle with quality lubricants will vastly improve service life and will provide optimum efficiency. Today’s properly maintained vehicles with 100,000 miles no longer consume oil and break with high frequency. Chemistry has played an important role and BG is one company who stands tall. The right chemicals can restore the ph balance in radiators so that acidity will not degrade hoses and internal metals in radiators and coolers. Other chemicals such as the BG transmission flush chemicals along with pulse flush equipment rinse the oxidation from the valves and other internal workings of transmissions. Fluid flushes without chemicals are “wallet flushes”.

    • What does it mean if my "check engine" or "service engine soon" light comes on?

      There are many sensors and computerized components that manage your vehicle’s engine performance and emissions. When one of these fails, the "check engine" light is illuminated. Although your car may seem to run fine, it is important to have the issue addressed to prevent long-term problems.

    • With the change of the season and the temperatures, do I need to have my car checked?

      It is a good idea to have your coolant checked to determine its freezing and boiling points to verify whether it needs to be changed. Have your air conditioner tested before the summer heats up, it is cheaper to fix before the season gets started.

  • Fluid Leaks

    • I see a fluid leak under my car, what is it?

      You can identify fluids by their color and consistency: • Yellowish green, pastel blue or florescent orange colors indicate an overheated engine or an antifreeze leak caused by a bad hose, water pump or leaking radiator. • A dark brown or black oily fluid means the engine is leaking oil. A bad seal or gasket could cause the leak. • A red oily spot indicates a transmission or power-steering fluid leak. A puddle of clear water usually is no problem. It may be normal condensation from your vehicle's air conditioner.

  • Vehicle Smells & Sounds

    • I smell something in /around my car, what could it be?

      • The smell of burned toast - a light, sharp odor - often signals an electrical short and burning insulation. To be safe, try not to drive the vehicle until the problem is diagnosed. • The smell of rotten eggs - a continuous burning-sulfur smell - usually indicates a problem in the catalytic converter or other emission control devices. Don't delay diagnosis and repair. • A thick acrid odor usually means burning oil. Look for sign of a leak. • The smell of gasoline vapors after a failed start may mean you have flooded the engine. Wait a few minutes before trying again. If the odor persists, chances are there's a leak in the fuel system - a potentially dangerous problem that needs immediate attention. • Burring resin or an acrid chemical odor may signal overheated brakes or clutch. Check the parking brake. Stop and allow the brakes to cool after repeated hard braking on mountain roads. Light smoke coming from a wheel indicates a stuck brake. The vehicle should be towed for repair. A sweet, steamy odor indicates a coolant leak. If the temperature gauge or warning light does not indicate overheating, drive carefully to the nearest service station, keeping an eye on your gauges. If the odor is accompanied by a hot, metallic scent and steam-from under the hood, your engine has overheated. Pull over immediately. Continued driving could cause severe engine damage. The vehicle should be towed for repair.

    • My car is making a terrible sound, what information will help?

      Squeaks, squeals, rattles, rumbles, and other sounds provide valuable clues about problems and maintenance needs. Here are some common noises and their definitions. Squeal - A shrill, sharp noise, usually related to engine speed. Click - A slight sharp noise, related to either engine speed or vehicle speed. Screech - A high-pitched, piercing metallic sound; usually occurs while the vehicle is in motion. Rumble - a low-pitched rhythmic sound. Ping - A high-pitched metallic tapping sound, related to engine speed. Heavy Knock - A rhythmic pounding sound.. Clunk - A random thumping sound. The more details you can provide us, the better chance of locating the problem quickly. Does the noise occur when the engine is cold or warm? Hot or cold outside, rainy or dry? Does the noise occur while driving or only when parked? These clues help the technician diagnose your problems faster, saving you time and money!

    • I hear an intermittent noise from the front of my car. Do I need to worry about it?

      Every noise should be checked by a qualified technician. Use you best judgment, if it sounds bad, get it checked right away. Quick action on a problem can many times save big dollars.

  • Oil Change

    • When should I get my oil changed?

      You should get your oil changed every 3000 miles or as recommended in your vehicle’s owner’s manual.

    • What is that milky brown engine oil?

      Milky brown engine oil is an indication of coolant in the oil. This can be caused by a blown head gasket (other gasket), a failed transmission cooler, or cracked casings. This condition is very serious and needs to be checked by a professional technician quickly.

    • What is synthetic motor oil?

      Synthetic motor oils can be a good choice for high output, turbocharged or supercharged engines, vehicles that are used for towing (especially during hot weather), or vehicles that are operated in extremely cold or hot climates. Synthetic motor oils, though several times more expensive than mineral-based motor oils, can improve fuel economy and provide longer intervals between changes. They also provide instant lubrication on start-up.

  • Troubleshooting

    • What should I do if my car starts to overheat?

      This is a very serious problem – if your car overheats for too long, you can damage your engine. As soon as possible, find a safe place to pull off the road and shut the engine off! Do not attempt to check the fluid level in the radiator as it can burn you. The best thing to do is have your car towed to a repair shop.

    • What dashboard lights should I worry about and which are just precautions?

      Every dashboard light is responsible for notifying the owner of issues that need to be addressed. If any of the following lights are lit you need to have your vehicle looked at: Engine light, Oil light, ABS light, Traction light, Tire Pressure light.

  • Electrical System

  • Fuel System

  • Improving Gas Mileage

    • How can you increase fuel mileage?

      To optimize gas mileage, check tires for proper inflation, make sure wheels are in alignment, check and replace filters, change Your oil regularly, keep your engine properly tuned, empty out your trunk of unnecessary items, observe the speed limit. These seemingly minor adjustments to your driving and maintenance habits can save on gas--and money!

  • Cabin Air Filters

    • Is a Cabin Air Filter the same as an engine intake filter?

      While most cabin air filters look like simple panel filters that are used to filter air to the engine, they are much more technologically advanced and contain an entirely different filtering media. Basically, engine intake filters protect engine components, whereas cabin air filters protect your lungs.

    • Where are Cabin Air Filters located?

      Cabin air filters are typically located behind a vehicle's dashboard, or behind the glove box. Others may be located in the engine compartment, typically in the cowl area.

    • What happens if they are not replaced at the recommended interval?

      In addition to the possibility of unpleasant odors, filters that have been left in service for over 20,000 miles can result in decreased heating and air conditioning performance caused by restricted air flow through the cabin air filter.
