Thanks guys,
yeah I've been reading a bit throughout this section on small blocks and in the cutlass section as well. All the reviews about the flex fans seem to make me think replacing that will not improve my situation.
--My fan shroud is in good shape, i guess. I mean it's there.lol.....and it's not falling apart or anything. I don't know if there's something specific i should look for, but it appears to be in good shape.
--I performed a coolant flush about a month ago when i replaced the thermostat and replaced it with new coolant. it didn't help my problem at all. The shop I took it to found a small leak around the thermostat housing and replaced the gasket which stopped the leak. I still have the same overheating condition though.
--I checked the fan clutch as best I could. I tested it just by spining the fan when the engine was off. It does not allow the fan to spin freely...in fact i only get about 3/4 of a revolution when the engine is cool. i read somewhere that was about what you're looking for. I do not know if it's a regular or heavy duty one. I just bought the car about 3 months ago so i'm still learning what has been replaced and what hasn't.
--the engine has about 10K miles on it and the transmission has about the same.
--as far as the radiator goes, i do not know if it's the original oldsmobile radiator or if it's been replaced and i'm not sure how many cores are in it. I will give it a look this afternoon after work and see if i can get some more info and post it. is there an easy way to tell how many cores are in it by looking at it, or will i just need to run the part number?
