engine noise when hot
 

my car is a 99 camry 2.2. with 178,000 miles. recently did a timing belt, water pump. been noticing when motor gets warmed up, there is an audible whirring noise coming from the engine compartment. not loud, but you can hear it. no noise upon start up. replaced the alternator because it was cheap. no change. what do I do next. looking to run this car into the ground, so I want to find the source of the noise. runs fine. tranny drained refilled at 150,000. any help appreciated. thanks, john

Use a section of rubber hose as a stethoscope to narrow down the area of the noise. Then report back.

unable to pinpoint noise. had the tranny drained and refilled. fluid was dark brown. still has noise. like I said, no noise when cold, only after warm-up.

Did the noise start after the timing belt change?

I think it did. new parts were from 1aauto parts. thought they were good parts?
