FAQs About Automobile Squeaks, Squeals and Rattles

Why do my brakes squeak?

The most common reason brakes squeak is that they are worn out. The squeak is the sound of the metal wear indicator on the brake pad coming in contact with the metal rotor. Your brakes are the top safety feature on your vehicle, so come by Gilmore's Auto Service and get them replaced right away. If you hear a squeaking only when you press the brake pedal the first 2-3 times when you first start driving in the morning it is the result of overnight moisture build up and likely nothing to worry about.

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 Gilmore's Auto Service 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 Walnut Creek can help you diagnose and repair leaks quickly and affordably.

Why does my car squeal when I start it in the morning?

A worn out cambelt (also known as a timing belt) will create a loud noise when you start your car's engine. The noise could range from squealing to hissing or rumbling. This is the sound of a cambelt that is about to break. If a cambelt breaks it can ruin your car's engine. Come to Gilmore's Auto Service and get it replaced right away.

Leaking Fluid FAQs

Why is water leaking on my foot on the driver's side?

The most common cause is a blocked air conditioning drain hose. This is a simple repair at Gilmore's Auto Service. There are other possible causes of water dripping on your foot on the driver's side of the car including a broken door seal or leaking heat exchanger.

What should I do if my car creates a small oil leak on my driveway?

If the spill is still wet, cover the stain with clay cat litter, sand, cornmeal, cornstarch or baking soda. This will help absorb the oil before it soaks into the cement. Once the spill has dried, sweep up the absorbent material. Then, wash away the remaining stain with water and soap. A small oil leak on your driveway is an indication that something is wrong with your car. Bring your car to Gilmore's Auto Service to get the problem diagnosed. Do not ignore an oil leak as it can seriously affect your car's engine.

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.
