I have a 1990 Chevy 1500, 350 2WD. I cannot get truck to stop overheating. I have replaced the intake manifold gaskets, collant temp sensor and connector (broke it while removing from sensor), thermostat and the radiator cap . I have flow of coolant in the radiator and I even took off the waterpump and the bearings and fins seem to be fine. I am leaning toward the radiator being partially clogged or the fan cluch going out. Which or what do you all recommend trying next?? Also, when I took the fan cluch off in removing the waterpump I noticed some considerable resistance in spinning the cluch, is this normal or reason to replace?? Please help, I cannot afford to continue replacing parts with no luck. Thanks ---

Does it hold pressure? Does it experience coolant loss? ---

Does not lose coolant other than the first time it overheated, but that was boiling over from the reserve tank… I had a friend come over with a gauge he put where the spark plugs go and he said everything was fine there, if that was what you were refering to.
