the fan wasn't coming on so I replaced the dohickey on the rad. with one fron O'cheapy's. It's working now, but seems to come on right away -even before the thermostat's open. Does anyone know where I can get the right one or at what temp it is s'posed to open?

Missing Background info Here: Which Subaru, Model, Year, Engine... Turbo or Non Turbo...

 

The Stock (Original) ThermoSwitch is Adjusted to Close the Circuit (Start the Fan) at 203º F on the EA82.

Kind Regards.

Oh yeah -it"s a 83 GL 1.8 non

A 1983 model and 1.8L, its engine is a EA81, those use a Single Spade connector, because the Thermoswith takes the Ground from the Rad, which is Metallic.

 

You can Use a Twin Spade there, by Grounding one of its Wires, usually the Black one; but you must be Sure to use the Proper Temperature Range.

 

Kind Regards.

where can I get one?
