We have a neat little problem with an 93 Prelude 2.2 swap The cooling fan (passamger side of radiator) does not cycle on when engine is running at about 3/4 temp. as i think it should ....however it will come on and stay on when engine and key is shut off. (engine hot) While fan is running with engine & key off....turning the key to the ON position turns the fan off. the fan wil run for up to an hour sometimes. DOES ANY ONE KNOW WHAT WRONG?
