    screeching on start up Z20LET

    Over the past month or so my zafira has been screeching terribly on start up. It also does it for about 1 minutes driving then it goes until the engine is cold again.

    Anyone got any pointers as to where the problem might be?

    Thanks

    starter motor stuck on? If so get it fixed asap as that can cause nice under bonnet fires

    Mine does this too - been told the manifold is blowing but when the heat expands it and it stops doin it after a few minutes, really gotta get it looked at.

    What about one of the belts slipping (PAS/alternator) - mine used to do this too (on an X20XEV)

    Just a thought!

    I had this on my astra gsi and we found out that the manifold bolts were just loose, if this helps

    when yo next start it up from cold have the bonnet popped and have a list to where it is coming from as u will be able to tell if its the area of the belts or the manifold/ where ever its coming from.

    could just be a warn belt as its normally a whistling noise from the manifold if its cracked or loose and a squeeling noise if its the belts!

    I had this once on an old Cav - one of the cv boots had split and sprayed it's grease onto the alternator drive belt - causing it to slip and squeal for the first few seconds of start up or when I drove it through a big puddle - worth checking.

    Thats the manifold gasket for sure.Same thing happened to me. Sounds like a skirling noise or a belt slipping, but its not the belts. When the maifold heats up and expands then it seals again.
