well i doubt now its the radiator... it only happens when going up hills under load or above 80kmh. temp drops once laod drops or under 80kmh... after talking with pigdogs brother, he thinks water pump impekkers are gone but others thought the clutch fan may be disengaging at load or high speed.

i still thoughtbottomhose might be collapsing under load.

might replace radiator with gemini one, bottom hose andswapping clutch fan for normal water pump fan. also thought the fa belt mightbe slipping.

this is a pain in the a$$.
