Friday, February 15, 1991 - North Shore News - 29 AUTOMOTIVES Oil changes should be determined by conditions Interpreting sounds can help in reducing maintenance costs OMINOUS CAR sounds tell you something may be wrong; under- standing their cause can help you and your mechanic find and cor- rect the problem before it becomes serious. Here are some of the more common noises, listed by Car Care Council. °®A ‘‘clunk”? from under the car when you start forward or vack up could be a warning thar a universal joint is failing. That's serious if it breaks and the drive shaft drops while you’re driving. If you have a front-wheel-drive car, you'll also get a clunking sound if you have a looseness in a CV joint (like a universal joint that connects the front wheels to the transverse axle). ®@ When you apply the brakes and hear a squeal or a scraping sound, that could indicate worn brake linings or pads. If allowed to continue, it could result in damaging brake drums or rotors, making the repair more expensive. ¢ A thumping sound from a tire could be caused by flat spots on the tread due to improper balance or aligament. It also could be tread separation, which could result in a blow-out. * The sound of ticking in the engine usually is a valve lifter, generally heard when the engine is idling. © A sudden screech from under the hood could be a worn or Joose drive belt. *A knocking or pinging from } Call today and book your appointment now. | Feb. 19, 20, 21 & 22.

You probably wouldn't hear this sound when the car is idling or in neutral. eA spitting sound or rumble from somewhere under the car could be an exhaust leak. This is a potentially dangerous situation due to poisonous exhaust fumes that could seep into the car. © If you raise the hood and hear a steady snapping sound that speeds up if the engine runs faster, it could mean a spark plug wire is loose or shorting out. The snapping sound is 2 spark jump- ing from the bad wire to the metal of the engine. emf you turn on the ignition switch and hear a clicking sound, but the starter does nothing, your battery may need charging or replacing. It also could be loose or corroded connections. The click- ing comes from the starter solenoid, which isn’t getting enough voitage to engage the starter. ¢ A whirring sound (but the car doesn’t start) could be the starter drive.

This can be lessened by increasing the frequency of oil and filter changes beyond the recommended amount. 2.

Keeping the outside of your engine clean will prevent dirt and grime from getting inside your engine. 4, Examine the dirty oil drained from your car’s engine for large dirt particles or metal shavings. The best way to do this is to strain the oil. Excessive particles or shavings may indicate undue engine wear. §. Keep up-to-date detailed ses- vice and repair records for your car to eliminate any guessing games later. Be sure to include what the original problem was; when the service or repair was done: end who did the work. 6. 1¥ you are having a problem Starting your car in the cold winter months try the less viscous 5W-30 grade motor oi! which wiil not thicken up as much as 10W- 40. 7.
