When ive been out for a thrash in my cav turbo and come to turn the engine off it always boils water over from the header tank (dumps loads)
i always let the engine run for a minute of so to cool the turbo down, but the water doesnt get chance!!
The temp gauge is showing about 85-90 before i switch off and the fan hasn't kicked in, but as soon as the ignition is off all the latent heat just causes it to boil
How can i cure this?
different fan switch?
fan on permanently ?
any help would be great
