Hey y'all,

Newbie here, looking at entering the wonderful world of owning a zook.

I went and looked at a 2002 Grand Vitara today, and the thing was solid! However after taking it for a test drive a high pitch whistle had developed in the engine.

Just wondering if anyone knows what would cause this?

Thanks in advance!

High pitched whistles are usually vacuum leaks, could also be a squealing/slipping belt.

Don't think it's the belt, I've had experience with that before.

The noise did seem to change/quieten with some revs, making me think that you are on the money. Not a hard fix hey?

Does anyone know of any other causes?

I don't believe that it is a belt as I have had that noise before on a previous car. The Noise is very loud and high pitched, almost ear-piercing.

The noise does seem to change/quieten with substantial revs, making me think that you are probably on the money. If so, its not a super hard fix is it?

Does anyone else have another idea of what it might be?
