PMSL thanks

Ok did it today when I had aircon on turned it off and went back down to 90 and held 

[gazareth]

the air con puts extra load on the engine so maybe that's why the temps rising that bit higher. but if your car aint losing water or gauge aint going in to red zone then it sounds like its fine. try running it for a week with the air con off and see how that goes.

[Kelvin1977]

Yeah I know maybe have to try that but chances of whole week of hot weather

Having a/c on or off shouldnt effect temp reading.. never ever saw temp reading change when using a/c on the mk4s i had

[gazareth]

isn't there an extra fan for the ac in front of the radiator?

[Kelvin1977]

Yeah I have never heard of anything like it

If your temp is going over 90 then I'd be looking at head gasket or more commonly, water pump failure

[Kelvin1977]

Yeah it had a water pump not long before I go it but think I will maybe change again make sure its a gen part
