Oil Filter FAQs
How often should oil filters be changed?
Consult your owner's manual to determine the maintenance interval for your vehicle's oil filter. Some manufacturers recommend that the oil filter be replaced every time you get your oil changed while others recommend every other time.
Why is my car leaking a sweet-smelling fluid?
If there is a sweet-smelling fluid leaking from your car, the most likely culprit is leaking coolant or antifreeze. A coolant leak can become a serious problem. If your vehicle gets too low on coolant or antifreeze, it will overheat and may cause engine damage.
FAQs About Automobile Squeaks, Squeals and Rattles
Why are my wheels making a chirping sound when I accelerate?
The most common reason why your car's wheels make a chirping or squealing sound, especially during acceleration is a bad wheel bearing. If you notice a grinding or grating noise coming from your wheel this can also be the sound of a wheel bearing beginning to fail. If you are in Pasadena, South Pasadena, Arcadia, Sierra Madre or the surrounding area, come by Walnut Smog and Repair and we can diagnose the problem quickly.
Why does my car make a noise when I turn the steering wheel?
If your car makes strange sounds or clicks when you turn the steering wheel the most common cause is a low steering fluid. Over time the steering fluid decreases and air enters the steering mechanism causing unwanted noises. Come to Walnut Smog and Repair to top off your fluid reservoir with power steering fluid. The noises should start to go away immediately. If the sound returns quickly your car could be leaking steering fluid. Our professionals in Pasadena can help you diagnose and repair leaks quickly and affordably.
