Had a few problems with a 99 camaro replaced the all the parts like the waterpump,sensor,therm,hoses,but not the radiator because it still looks good. I took all the air out of the radiator after leting it run for awhile it drives good but every morning i have to add water to the radiator about a 12 oz cup or more. The car does not smoke or overheat it runs good can someone tell me if this normal.

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!

Replying to: toyota83 (Nov 05, 2009 8:25 pm) This sure could be causing overheating. While at idle or driving slowly, the bad clutch is not turning the fan, which could cause overheating. 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.
