Reply To: Engine overheating

Hi folks. It’s been a long time since I last visited the forum.  No excuse, but I have to admit that it has taken months to get to the bottom of the overheating problem and at times I have had difficulty in motivating myself to work on the car. I’ve tried everything that you good people advised. Head off and cleaned the water jacket, flushed out the radiator,  sent back the radiator for cleaning and also removing layers of paint that the radiator people insist on spraying on, checking the correct fitting of the fan and checking the timing. So we narrowed the problem down to the radiator.

I was always puzzled as to why, when I held the radiator up to the light that I could not see through it in places.  This despite extensive cleaning. So I found another radiator which though more battered than mine had clearly been refurbished and yes I could see through the entire unit clearly. Long story short, car ran for half an hour static in the garage and temperature never went above 80 degrees celsius.

I think I finally solved the problem although I still do not know exactly what is wrong with the old radiator. Maybe collapsed cores.

Many thanks for all the help. Tatenda!
