I have a 1997 GMC Jimmy, 91000 miles. It starts to overheat and has no heat from the vents, then it will suddenly "kick in"-- the temperature gauge will suddenly drop and heat comes from the vent. It only does this once in a while, not consistantly (about every 5th time its driven). I just had the thermostat replaced 2 months ago. I dont think its the new thermostat. I had someone tell me it seems like the radiator and the intake manifold gasket. While he is skilled, he's not a professional, however. Is that a plausable cause for the problem, given its not the thermostat?
have the same problem?
