Failing that it could be the computer control box. Around that era some boxes would fail at certain temperatures and then after cooling come good again. Hope this might help. col

Check the timing to make sure its properly lined up, the belt may have slipped and jumped a tooht, or loose tensioner on the timing belt. Confirming the timing will give you a good clue as to where to look next.

please clarify. if its heat as interior air temperature, it shouldnt have anything to do with the actual engine componets and more something to do with your switches inside? If its heat as in the temperature of the engine, does the engine run because if it does, it has to create heat.

front crank seal or rear.
Front involves cambelt removal so you might think of changing that too
