my radiator fan doesnt either nd i think its an electrical problem.i tested the cooling fan relay fuse nd its not getting any circuit(used a 5amp fuse instead of a 7.5amp fuse ran the car nd the fuse didnt melt).so if the cooling fan relay fuse is not getting circuit then its obviously not the cooling fan relay so its has to be radiator fan switch rite?does anyone kno where its at?
p.s the engine temperature guage isnt working but that wouldnt be a problem rite?

I would start with the engine temp sensor, that could be the problem, if not that then go to the fan switch. If you need to just straight wire the fan to a switch for now.

You can test whether the coolant temperature switch in the thermostat housing is bad by uncoupling the 2P connector and putting a jumper wire across the two terminals of the connector. If the switch is bad, the radiator fan will run continuously when the ignition key is turned to ON.

thnx dude but r u talkin bout the coolant temperature switch(beside the lower radiator hose) or the coolant temperature sending switch(rite under the dizzy)?

Former User

I am referring to the coolant temperature switch (2P connector) located on the thermostat housing.

The sending unit for the temperature gauge has a 1P connector and is located beneath and forward of the distributor.

Right next to the sending unit is the coolant temperature sensor (I think 2P connector) that talks to the ECU.

i jumped the eng.cool.tem.swtch nd it worked.i also ran the car nd noticed that the lower radiator hose was ice cold so it doesnt neccarily hav to be the ECT switch rite?could the fan not work cuz of a bad thermostat?

Former User

Yeah, first make sure the thermostat is not stuck closed.

esean93

wait im confused.which one is the thermostat housing?the housing where the upper rad hose goes or where the lower rad hose goes?the ect switch is on the housing where the lower rad hose goes.

Former User

The thermostat is located in the housing where the ECT switch is located, not where the ECT sensor or sending unit is located.
