quick question: should the fan clutch turn lighter when turned by hand when hot than when cold? this is the situation right now.

and the temperature readings are based on a mechanical gage. actually i also have the electric stock gage working but the mechanical is more sensitive to changes....nasa 140F na yung mechanical, yung electric gage nasa Cold line pa lang. saka lang pupunta sa gitna ng 1st and 2nd line after say 15 minutes that is at 180F. but at times, the stock electric is about in excess of a hairline above the 2nd line when the mechanical gage reads >212F.
mate, ano klase ba yung fan mo, bi-metallic strip and control piston or yung bi-metal spring connected to an opening plate? meron din Flex-Fan..

if your condenser fan is in good working condition i would suggest to check your rad fan for possible trouble...

run the engine at a fast idle speed until normal operating temperature is reached. stop the engine and immediately check the effort required to turn the fan (take due care, use gloves). if considerable effort is required, it can be assumed that the coupling is operating satisfactorily but if very little effort is required to turn the fan, it is an indication that the coupling is not operating properly and should be replaced.

if the clutch fan is the coiled bi-metal spring type, it may be tested while the vehicle is being driven by disconnecting the bi-metal spring, and rotate it 90 degrees counterclockwise to disable the temperature-controlled free-wheeling feature and the clutch performs like a conventional fan. if this cures the overheating condition, replace the clutch fan.
