    Preventive Maintenance


    What are the consequences of postponing maintenance?

    Many parts on your vehicle(s) are interrelated. Ignoring maintenance can lead to trouble: specific parts — or an entire system — can fail. Neglecting even simple routine maintenance, like changing the oil or checking the coolant, can lead to poor fuel economy, unreliability, or costly breakdowns. It also may invalidate your warranty.

    What maintenance guidelines should I follow to avoid costly repairs?

    Follow the manufacturer's maintenance schedule in your owner's manual for your type of driving. Some repair shops create their own maintenance schedules, which call for more frequent servicing than the manufacturer's recommendations. Compare shop maintenance schedules with those recommended in your owner's manual. Ask the repair shop to explain — and make sure you understand — why it recommends service beyond the recommended schedule.

    Protecting Your Repair Investment


    What warranties and service contracts apply to vehicle repairs?


    There is no "standard warranty" on repairs. Make sure you understand what is covered under your warranty and get it in writing.

    Warranties may be subject to limitations, including time, mileage, deductibles, businesses authorized to perform warranty work or special procedures required to obtain reimbursement.

    Check with your state Attorney General or local consumer protection agency for information about your warranty rights.

    Heading Off Problems

    The more you know about your vehicle, the more likely you'll be able to head off repair problems. You can detect many common vehicle problems by using your senses: eyeballing the area around your vehicle, listening for strange noises, sensing a difference in the way your vehicle handles, or even noticing unusual odors.

    Looks Like Trouble

    Small stains or an occasional drop of fluid under your vehicle may not mean much. But wet spots deserve attention; check puddles immediately.

    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 or exhaust.

    Smells Like Trouble

    Some problems are under your nose. You can detect them by their odor:

    • 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-sulphur 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.
    • Burning resin or an acrid chemical odor may signal overheated brakes or clutch. Check the parking brake. Stop. 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.

    Sounds Like Trouble

    Squeaks, squeals, rattles, rumbles, and other sounds provide valuable clues about problems and maintenance needs. Here are some common noises and what they mean:

    Squeal — A shrill, sharp noise, usually related to engine speed:

    • Loose or worn power steering, fan or air conditioning belt.

    Click — A slight sharp noise, related to either engine speed or vehicle speed:

    • Loose wheel cover.
    • Loose or bent fan blade.
    • Stuck valve lifter or low engine oil.

    Screech — A high-pitched, piercing metallic sound; usually occurs while the vehicle is in motion:

    • Caused by brake wear indicators to let you know it's time for maintenance.

    Rumble — a low-pitched rhythmic sound.

    • Defective exhaust pipe, converter or muffler.
    • Worn universal joint or other drive-line component.

    Ping — A high-pitched metallic tapping sound, related to engine speed:

    • Usually caused by using gas with a lower octane rating than recommended. Check your owner's manual for the proper octane rating. If the problem persists, engine ignition timing could be at fault.

    Heavy Knock — A rhythmic pounding sound:

    • Worn crankshaft or connecting rod bearings.
    • Loose transmission torque converter.

    Clunk — A random thumping sound:

    • Loose shock absorber or other suspension component.
    • Loose exhaust pipe or muffler.

    Feels Like Trouble

    Difficult handling, a rough ride, vibration and poor performance are symptoms you can feel. They almost always indicate a problem.


    • Misaligned front wheels and/or worn steering components, like the idler or ball joint, can cause wandering or difficulty steering in a straight line.
    • Pulling — the vehicle's tendency to steer to the left or right — can be caused by something as routine as under-inflated tires, or as serious as a damaged or misaligned front end.

    Ride and Handling

    • Worn shock absorbers or other suspension components — or improper tire inflation — can contribute to poor cornering.
    • While there is no hard and fast rule about when to replace shock absorbers or struts, try this test: bounce the vehicle up and down hard at each wheel and then let go. See how many times the vehicle bounces. Weak shocks will allow the vehicle to bounce twice or more.
    • Springs do not normally wear out and do not need replacement unless one corner of the vehicle is lower than the others. Overloading your vehicle can damage the springs.
    • Balance tires properly. An unbalanced or improperly balanced tire causes a vehicle to vibrate and may wear steering and suspension components prematurely.


    Brake problems have several symptoms. Schedule diagnosis and repair if:

    • The vehicle pulls to one side when the brakes are applied.
    • The brake pedal sinks to the floor when pressure is maintained.
    • You hear or feel scraping or grinding during braking.
    • The "brake" light on the instrument panel is lit.


    The following symptoms indicate engine trouble. Get a diagnosis and schedule the repair.

    • Difficulty starting the engine.
    • The "check engine" light on the instrument panel is lit.
    • Rough idling or stalling.
    • Poor acceleration.
    • Poor fuel economy.
    • Excessive oil use (more than one quart between changes).
    • Engine continues running after the key is removed.


    Poor transmission performance may come from actual component failure or a simple disconnected hose or plugged filter. Make sure the technician checks the simple items first; transmission repairs normally are expensive. Some of the most common symptoms of transmission problems are:

    • Abrupt or hard shifts between gears.
    • Delayed or no response when shifting from neutral to drive or reverse.
    • Failure to shift during normal acceleration.
    • Slippage during acceleration. The engine speeds up, but the vehicle does not respond.

    Trouble Shooting

    Car, Boar, Cycle trouble doesn't always mean major repairs. Here are some common causes of trouble and techniques to help you and your technician find and fix problems:

    • Alternator — Loose wiring can make your alternator appear defective. Your technician should check for loose connections and perform an output test before replacing the alternator.
    • Battery — Corroded or loose battery terminals can make the battery appear dead or defective. Your technician should clean the terminals and test battery function before replacing the battery.
    • Starter — What appears to be a defective starter actually may be a dead battery or poor connection. Ask your technician to check all connections and test the battery before repairing the starter.
    • Muffler — a loud rumbling noise under your vehicle indicates a need for a new muffler or exhaust pipe.
    • Tune-up — The old-fashioned "tune-up" may not be relevant to your vehicle. Fewer parts, other than belts, spark plugs, hoses and filters, need to be replaced on newer vehicles. Follow the recommendations in your owner's manual.
    • Lack of maintenance — Sometimes in our busy lives we neglect or forget to upkeep the services on our vehicles, maintenance is like insurance, keeps the repair costs down.
