Renault Clio - Heating and Cooling - Over heating Problem
I have a 1992 Mk1 1.2 Clio which persistently overheats.
I have flushed and cleaned the rad many times and refilled with the best antifreeze mixture I can get. The water pump is ok and the heater works fine so I assume I am getting no airlocks.
I have tested the fan and that is also fine.
I noticed today that the seal in the header tank cap is damaged.
Could this be the cause of the problem?
I assume that if the cap is faulty the coolant will boil at a lower temperature and flash to steam.
Any advice would be most appreciated.
