Excessive pressurising of the cooling system is normally the first symptom I see on XU/XUD HG failures, together with coolant loss.

dont see any coolant loss probelm i got is lack off bleeding nipples on the coolant system

Unless you can bleed it properly, you'll never get the air out and you'll forever have problems with heat... Need to get a bleed point at the top of the system on the matrix hoses and on the bleed line from the thermostat housing.

cheers ruan i think that is my problem only got 1 bleed nipple that comes of heater matrix and thats it

Come to think of it, I don't think I actually have any bleed points on mine.... Though I have the upper return hoses leading back into the header tank. Home Brew Lash up cooling system

Might help if you drill a small hole in the thermostat too by the sounds of it if you are lacking in bleed points.
