Q: Engine squealing when idling

asked by on

After driving for a while and then idling, I hear a squeal coming from the engine. It sounds like it is the fan clutch, and once I start driving, it goes away. It only starts doing this when the engine is hot.

Hi there. A squealing noise is a common sign that the rotating parts such as your belts are slipping on their pulleys. A worn belt will make this noise due to the loss of tension and gripping ability of the belt. A simple replacement of your belt(s) will solve this issue.
