Possibly the cap but more likely needs bleeding again.

I am relying on you to sort his,

as my niece & Boyfriend chappie, have recently bought a van, and it has started doing the same, so I have a certain amount of interest in this .................................... So please hurry up, will you.

think its going to be the head gasket ! think it will av to be a new engine or just get shot

Post by **jason k** » 25 Mar 2010, 08:04

sounds like the gasket.
take it to a garage and get them to sniff the coolant for the prescence of combustion gas in the water.

that will answer your problem one way or the other.....
