Clicking noise coming from car while being driven and during idle. Turned out to be the serpentine belt tensioner was not functioning properly. Repaired for $160 total
This the 2nd Sunfire in 2 yrs to have the power steering go out and the tensioner pulley slip the belt. 2000 and 2001 car.
A loud clanking, slapping sound suddenly began coming from under the hood while driving. The car was driving fine before and during. I did not feel safe driving, so I pulled over and had the car towed. The service center was able to diagnose the problem as the main drive belt and tensioner. The belt was in bad shape. It cost $300 to replace.
My car started up fine no noise, no clicking, nothing. I put it in reverse and it just stopped, I kept trying to
start it wouldn't turn over and it hasn't started since. I was told its the timing belt. It hasn't been fixed yet I'm sending it to a shop next week.
