Q: Whining noise from the 4 cyl engine.

asked by on

There is a constant whining noise from the engine. It does not seem related to the power steering since it does not get louder when I steer one direction or another. It just seems constant and gets louder and quieter with acceleration and deceleration. It is directly related to the speed of the engine. Please advise. Thanks marcus

My car has an automatic transmission.

If you are hearing the noise at idle when the car is not moving, generally the noise you are describing originates in the engine, the transmission (torque converter runs even at idle), and/or the accessory drives. However, if there is no whining when the car is not moving but rather the noise starts at speed, that could be a wheel bearing issue. If the sound occurs when the car is stationary, if the sound is not really obvious (pinpointed) on the mechanic’s initial inspection, a quick diagnostic can be performed by simply taking all of the belt driven accessories out of the picture by disconnecting the drive belts and then very briefly running the engine. If the sound disappears, the faulty component is then isolated amongst the accessories and pulleys. If the sounds does not disappear, that means the noise originates within the engine and/or transmission. If the sound occurs only once the car is moving, remote wireless microphones can be used to identify the wheel position that the noise originates from and at which there could be a failed wheel bearing. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a vehicle noise diagnostic and the responding certified mechanic will get this resolved for you.
