FAQs About Automobile Squeaks, Squeals and Rattles
Why is my car making a squealing noise?
It may be a slipping fan belt. Listen for warning signs such as squeaking or chirping noises. These sounds are often caused by misalignment between the belt and pulley. If you come by BJ's Automotive in Simi Valley, our professional auto repair technicians can inspect and realign the belt to stop the noise and address the problem before the belt fails completely.
Why does my car make a noise when I turn the steering wheel?
If your car makes strange sounds or clicking noises when you turn the steering wheel, one possible cause is low power steering fluid. When the fluid level drops, air can enter the power steering system and cause unwanted noises.
Come to BJ's Automotive to have the power steering system inspected and the fluid level checked. If the noise returns quickly after the fluid is topped off, your vehicle may have a power steering fluid leak. Our professionals in Simi Valley can diagnose the cause and recommend the appropriate repair.
Why does my car squeal when I start it in the morning?
A squealing noise when starting your vehicle can be caused by a worn or loose belt. Depending on the vehicle and the source of the noise, the issue may involve an accessory drive belt or another belt-driven component. Because some belt failures can lead to serious mechanical problems, unusual or persistent noises should be inspected promptly. Come to BJ's Automotive and our technicians can determine the source of the noise and recommend the proper repair.
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 typically a straightforward repair at BJ's Automotive. Other possible causes of water leaking onto the driver's side floor include a damaged door seal or a leaking heat exchanger. Our technicians can inspect the source of the leak and determine the appropriate repair.
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 an absorbent material such as clay cat litter, sand, cornmeal, cornstarch, or baking soda. This can help absorb the oil before it soaks further into the concrete. Once the spill has dried, sweep up the absorbent material and clean the remaining stain with soap and water.
A small oil leak on your driveway is also an indication that something may be wrong with your vehicle. Bring your car to BJ's Automotive so the source of the leak can be diagnosed. An oil leak should not be ignored because loss of engine oil can eventually lead to serious engine damage.
Why is my car leaking a sweet-smelling fluid?
If you notice a sweet-smelling fluid leaking from your vehicle, coolant or antifreeze may be the source. A coolant leak can become a serious problem if left unaddressed. If the coolant level becomes too low, the engine may overheat and potentially suffer engine damage. Have the vehicle inspected promptly to locate and repair the leak.
