The Patchman

I have a 89 Prelude with a 90 motor The cooling fan comes on when the car is off and stays on till the batery is dead. Sometimes I can turn the key to the on position and the fan will stop but goes right back on when I turn the key off.

Sure could use some help with this one

Thanks

Check your fuses and relays. Do you have a check engine light?

The Patchman

The Check engine light is on and If i take the heat sensor wires off the fan relay it still stays on

Its gotta be a coolant temperature sensor....one of the fan relays my be stuck open..let me grab my book real quick.

The Patchman

Thanks for your help The plug I am removing is in the thermostat housing is that the right one?

F22B Prelude

Get the one under the radiator...its screwed into the bottom of the radiator

The Patchman

Thanks I will try that. It sure dont look like its an easy one to get to lol

It seems decent in the book...I think you were pulling out the Coolant Temp sensor. The one your looking for is on the bottom of the radiator right next to the radiator hose.
