Title: painic!! overheating! engine overheating?
Post by: rfn_hodgson on 13 May 2012, 15:17: Hey guys i was wondering if i could pick your brains. When im driving along since last night as soon as the turbo kicks in or at around 2000 revs the temp kicks up its not overheated yet but what do you think it is?

Its a 1.8 t 180 bhp auq

Cheers lads

You will have to remove the cam belt to fit the new pump :smiley:

good point.

a new belt is only about fifteen pounds, but the labour for a new pump is the same as having your belt done anyways. about 250 to 300 all in. :sick:

Post by: Wazzzer on 13 May 2012, 19:37: just an easy way to see if there's any water circulating :wink:

My mother in laws partner had the same problem with his XK8, plastic impeller had gone on that too :rolleyes:
