I have a D15b and i am having a very weid cooling problem.
the car started getting very hot and overheating when i accelerated, but once i was cruising it would stay relatively cool.

Now it over heates no matter what.

I have had the radiator flushed, i changed the water pump, took out the thermostat. changed hoses that had in cuts and the car still overheats. I also changed the head gasket cuz i thought that it may have been blown.

Nothing helped. can anyone give any suggestions ???

 

changed rad cap???
