Screeching at cold startup

[Scouser]

Its been frequent days below zero here. My car is garaged but it's still very cold.

Just noticed that on the odd occasion, when i start the car, I hear a loud screeching sound. It goes away immediatly the car is started. No warning lights show. Car starts always 1st time. No smoke. Idles perfectly. Just a real loud screem for about 2 seconds. It seems to happen only when the car is cold.

It happens occasionally and not always. in fact I have tried many times to record the sound but it just refuses to screech when I want to record it :huh:

Any ideas what it could be?

My first thought would be the Polyrib belt... or possibly the air pump going bad.

Yea I thought belt too but it only had a service 2 months back (3k miles).

you would think they checked the belts. Where is the air pump. Is this something i should be worried about?

It's going in for its 2nd RMS in a few weeks so I will get them to check it then. Just thought maybe you would know what it would be.

Cheers,

If you're close enough to Goodison it could still be the sound of Ronaldo after Wayne's tackle...!

One question. does the car screech on start up if it's hot? If not it might indicate a slipping belt

Le chef, notice my 996 is blue ;)

No it onlyseems to screech at cold start. Will have the belts checked. Thnxs.
