Thanks TB - will have a look later.

I'm keeping an eye on this thread as my car has been like this for a week or two now. It goes away after it has ticked over for a couple of minutes after start up. Putting the air con on at low revs brings the whistle/screech back. On mine it is definitely not the secondary air pump. It is very, very gradually getting worse i.e. takes longer to go away. the car isn't overheating or losing water. Just as well as it is 34 Deg C here.

If I decide to change the water pump what else do I need to/or is sensible to change at the same time e.g. tensioner, belt? Very approx how much UK money should I budget on parts? The car is a 2.5 auto V6.

thanks, olive

olive, in your case, run car briefly with aux belt removed, see if that cures it?

Remember, on v6, with no aux belt, you have no waterpump, so don't use it like that!

waterpump should be about 25-30 pounds in the UK.

to change it you need to do all of the strip down needed to do the cambelt, so maybe consider doing that if you have access to the locking/timing kit.

Mine sounded like this.  No warning just heard the noise as I slowed through traffic

Came home on the back of a tow truck and new Water Pump fitted next day.
