cooling fan running high on cold motor
I just finished replacing my valve cover and started the car up for the first time and now for some reason the cooling fan seems to be running at what sounds like max. The engine is cold obviously. Any ideas? Is there a sensor i may have forgotten to reconnect or something??
edit: NM! found 2 plugs i forgot to plug back in. We're good! lol

You could contribute to the knowledge (anti-ignorance ;-) base here by posting photo of the "2 plugs." My SWAG would be that ONE of them was the Connector to the Refrigerant Pressure sensor on the High Side refrigerant line from the condenser to the Expansion Valve? That WILL cause E-Fan to run at high speed if disconnected or defective sensor. Thanks, George |
