Tires

• 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.
• How often should I have my car aligned?
  Vehicle manufacturers as a general rule recommend an annual alignment check. Unless there are obvious handling or wear problems this may not be necessary. As a general rule, have your vehicle aligned with every set of new tires, any suspension or steering part replacements, and at least every two years.
• What are the benefits to Nitrogen filled tires?
  The single biggest reason for tire failure is lack of maintenance of tire pressure. In fact, 54 percent of all vehicles on the road have low tire pressure. Oxygen in compressed air can permeate the tire wall reducing tire pressure. With nitrogen, diffusion is 30 to 40 percent slower than oxygen. As a result, nitrogen maintains tire pressure longer than ambient air. Maintaining tire pressure can boost fuel economy by as much as 6 percent. Nitrogen disperses heat more quickly than ambient air. By restraining the heat in the tire and reducing rolling resistance, you get better fuel economy. Longer tread life. With quicker heat dispersion, you get a cooler running tire which helps extend tread life and reduce tire failure. Nitrogen also prevents oxidation which can not only lead to tread separation and belt failure but, when combined with moisture, corrode rims. In fact, moisture can result in rust flakes that can fall into the valve stem, block the valve and cause under-pressurization. It can even cause the valve stem itself to rust. Slow chemical aging. Filling a tire with nitrogen also significantly slows the chemical aging process of the tire's rubber components. This leads to fewer catastrophic failures like blowouts. Slower aging lengthens tire core life, which yields extra retreads and lower fleet costs.
• 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

• If I don't take my car to my car dealer for maintenance or repair will I void my warranty?
  As a vehicle owner you should know about the Magnuson Moss Warranty Act. In 1975 the US Congress passed the Magnuson-Moss Warranty Act – a federal law that governs consumer product warranties. Among other things Congress wanted to ensure that consumers could get complete and straight forward information about warranty terms and conditions. In short the Magnuson-Moss Act gives you these rights. Generally your vehicle manufacturer’s warranty cannot require you to return to your auto dealer for vehicle maintenance – or to use only the brand of replacement parts offered by that dealer. By law your vehicle’s manufacturer’s warranty will stay in effect when you have regularly scheduled maintenance performed at a qualified facility that use appropriate parts and procedures.
• Why does my vehicle's maintenance schedule recommend so many fuel system services?
  Modern engines have long abandoned carburetion with its many parts destined for failure in favor of simple and direct electronic injection of fuel. No longer are we shackled with the necessity of constant adjustment or repair. A properly maintained fuel delivery system today offers much improved reliability and efficiency than those systems of old. Millions of cars today run at a level of efficiency considerably reduced, due to the high concentration of carbon deposits accumulated in the fuel injection system, intake valves, combustion chambers, oxygen sensor and catalytic converter. Carbon build-up clogs fuel filters, reduces fuel flow, distorts fuel spray patterns, limits fuel automation and decreases combustion efficiency. Carbon build-up gradually robs your vehicle of performance and fuel economy, and may cause numerous problems such as engine malfunction, high emissions, excessive fuel consumption, loss of performance, rough idling and hard starts. Simply infusing an additive into a gas tank will not adequately decarbonizes injectors, cylinder heads, valves, intake plenums, exhaust emission sensors, and other critical components.
• Is it really necessary to replace my timing belt at the recommended interval?
  YES. The failure of a timing belt in many cars can result in major engine damage. The cost of repairing an engine with a broken timing belt is much greater than the cost of a timing belt replacement.
• What is the difference between maintenance and safety?
  Maintenance is done to prevent any future problems from occurring to the vehicle. Safety is to prevent any incident that would cause damage to the vehicle, to you or to the driver who is driving next to you.

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.
• I have a leak under my car. How can I tell what is leaking?
  The coloring of the liquid identifies the type of liquid. Coolant Fluid is orange or green, Engine fluid is Brown or Black, Transmission Fluid is Red or Pink, Power Steering Fluid is Light Brown, Differential Fluid- Brown. depending on the leak it could mean trouble, don't wait until it's too late!

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

• How often should I change my oil?
  Most car manufacturers say to change your oil every 7,500 miles unless you drive in severe conditions. Severe conditions are defined as dirty or dusty roads, extremely hot or cold climates, a lot of stop and go driving, taking long trips or if you tow a trailer. If you answer yes to any of the severe driving conditions, your vehicle falls into the severe conditions category, or the 3,000 mile oil change interval.
• 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.

Electrical System

• How to make sure my car battery has a good electrical connection?
  Battery cables and terminals should also be cleaned and inspected to make sure they provide a good electrical connection.
• I need to replace a burned out fuse, what should I do?
  Always replace burned-out fuses with ones of the same amperage (printed on the fuse) and note that if a fuse continues to "blow," you should have the circuit checked professionally by one of our technicians for defects.

Fuel System

• When should I replace my car's fuel filter?
  To help ensure dependable, trouble-free performance, replace your car's fuel filter approximately every 30,000 miles or as recommended in your vehicle's owner's manual.

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

• What is a Cabin Air Filter?
  Cabin air filters filter the air that comes from the outside of a vehicle into the passenger compartment. They were originally designed to remove solid contaminants like dust and soot from circulating inside the vehicle. These filters can now also absorb gases and odors. Cabin air filters may also be known as passenger compartment filters, pollen filters, or dust filters.
• When did Cabin Air Filters come into being?
  Cabin air filters first appeared in European vehicles in the mid-1980's. They began appearing in North American vehicles in 1994.
• 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.
• Why are Cabin Air Filters important?
  Air quality is becoming a major concern for many people - outdoors, in our homes, and now even in our automobiles. An estimated 50 million Americans suffer from hay fever and other allergy-related problems.
• 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.
• How often should they be replaced?
  Vehicle manufacturer recommendations may vary, but the general guideline for replacing cabin air filters is every 12,000 to 15,000 miles, or at least once a year.
• 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.
