Noisy

Don't mind the knocking sound it actually doesn't knock its just the video. However, that high pitch is what I'm asking about. At first i thought it was the belt, but now I'm starting to think its a pulley. Sounds like it's coming from the right side, maybe the middle. Any ideas?

 

Nobody?

 

Sorry, But with out actually being there and hearing or seeing it personally I can't offer much help.

 

If you rev the engine, does the noise increase velocity with the engine?

Theoretically... belts don't make any noises unless they're slipping on the pulley and its a high pitched screaching sound usually at the beginning when you step on the gas.

It could be a bearing going bad...a bearing inside one of the pulleys. You have to figure out which pulley/bearing is making the noise.

Sometimes...if you spray a very small amount of light oil (WD, PB, etc) on the bearing from the outside, enough will get inside to 'quiet' the bearing - and hence, you'll know which bearing it is. DO NOT get any oil on the belt or pulley surfaces!!!

 

I can't help from the video.... Need more info. Year, Mileage, etc. Usually, IMO, the first to go is the water pump bearings .... but can't tell .

 

It doesn't change pitch with the rev of the engine. After i run the engine for 15 minutes the noise goes away. 2006 92xxx miles
