Hey I have a 1986 toyota pickup truck. I had a radiator leak so i got a new radiator. Then the water pump leaked so i replaced that and the thermostat, my truck will still over heat but not all the time, only sometimes. Do you think it could be a bad waterpump or therm? there is no white smoke or water in the oil. The mechanic said I needed to change my clutch for the fan, he was able to stop it with his hand. Sometimes I smell a coolant smell from the engine area but not the exhaust. Sometimes ill have to top off the radiator, there is no leaks at all though. Any help would be awesome, the mechanic pressure tested it and he said was fine. faulty pump? Thanks for the help!

When driving faster, you are getting adequate air flow thru the radiator, and are not overheating. This may be why you overheat sometimes and sometimes not. A way to test for a bad clutch - Get the car hot, warmed up. Idle the car, open the hood, have someone turn the ignition off. The fan should stop turning very quickly. Just a few spins, then stop. This indicated the clutch is working, meaning when hot it has high friction and will make the fan spin. If the fan continues to spin, it's broken - when hot it has no friction to turn the fan.

I POSTED A PROBLEM WITH MY CAR I TOOK IT TO PEPBOY'S AND THEY TOLD ME THAT IT WAS THE HEADS BUT THE CAR SHOWS NO SIGNS OF THEM GOING BAD TOOK IT TO ANOTHER MACHANIC AND HE SAID IT SHOW THAT IT IS RUNNIG GOOD AND NO SIGNS. IT DOES NOT MISS FIRE OR HEAT UP IT STAYS AT THE RIGHT TEMP 190 TO 210 BUT IT NEED WATER EVERYDAY ABOUT A 20 OZ CUP OFF WATER. THE COOLANT RECOVERY TANK IS BROKE ON THE TOP WERE THE BATTERY SITS. THE MACHANIC TOLD ME IT IS NORMAL NOT THE SEE WATER IN THE RADIATOR BUT WHEN I TURN ON THE CAR THE WATER WILL RISE TO THE TOP. I GUESS THE ONLY WAY I WILL KNOW IF I LET SOME MACHANIC TAKE THE HEADS OFF AND GET THEM CHECKED.
