    Annoying Squeal - Please help!!!

    Over the last few week, I have noticed a squeeling noise coming from the engine of my Astra SXi (H series) when I'm slowing down, or the engine is ideling.
    It only starts after I've been driving for at least 20 minutes when the engine has warmed up. And if you turn the ignition off whilst its making the noise, it continues for for a few seconds after the engine has stopped.

    I had the drive belt changed a few weeks ago, but it hasn't sorted the problem.

    It sounds like air under pressure being squeezed out from somewhere.

    Any suggestion would be helpful, and yes I've tried WD40 on the new belt.

    Yes, its a 2004 (New Shape), so Air con is standard. Had that regassed earlier year and had no problem until a few weeks ago.

    As you dont use it very often, there is a good chance that some of the gases will have leaked. Mine made a hissing noise a few seconds after turning engine off. (04 mk4)

    Since it went into garage and had a condenser replaced and regassed, running nice now, so i can be freezer cold in this great summer we are having!

    Might be worth checking the air con system?

    Many thanks for that. i ran the air driving home last night, its working fine. Somebody at work told me to forget hissing noises as its problerly the drive belt tensioner. Ok when cold, but not running right as the belt warms up, even if it is a new belt. Could this be the case??
