My fan will not kick on, I replaced the sensor on the engine. The fan will kick on when I turn on the A/C. Could my problem be the relay and if so where is it. Thanks Eric

 

Hey BBCFAN, just got a question first do you have dual fans or a single one?
Also do you have a V8 or V6?

If it turns on with the aircon it is not the relay.
What sensor/switch did you replace, Drivers side or passenger side?

 

Single fan 305 TBI the sensor I replaced was on the top of the intake on pass. side.

 

Ah ok well im not the best on the TBI systems so im not shure what sensors there are in that setup, Sry i couldent help more.
Hopefully someone else can help.

 

Ok thanks I think the one I replaced is for the temp gauge. Had to order a new one so I will see what it looks like when I get it. But maybe someone else could chime in.

 

hey guys um i have a 92 Z28 305 TPI cam, headers Y-pipe, deleted out cat, flowmaster exhaust. my passanger side fan is not kicking on, so i checked the fuse its fine, so i swaped the wires, took the driver side and put it on the passanger side and it still didnt kick on, so i put the wires back to the right fans and now neither one will kick on, and i know that the driver side one was working cause it was working yesterday may 23rd 07, any ideas? i didnt wanna start a new thread.

 

I got the same problem with my '92 Camaro,I got dual fans and neither one will kick on unless I turn on the A/C otherwise I need to take Water Tempreture connection off then the fans will work fine I replaced the sensor with no use,I got 350 L98 TPI

 

me too, i have the same problem, i have a 5.0 305 tpi and the fan does not turn on. the fan motor works cuz i tested it already just doesant kick on. hey where is the fuse for the fan ? oh and for BBCFAN's ? well i dont know if all relays are in the same place but i found mine right by the battery and behind the pass side headlight, hope that helped

 

I don't imagine TBI being much different than TPI... if the fan kicks on at all your motor and relay is good. Your temp sensor for your gage should be in the driver's side head between #1 & #3 spark plugs. Your temp sensor to the ECM should be in the intake manifold and the fan temp switch should be in the passenger side head between #6 & #8 plugs.

 

thanks for that info, but how about the fan fuse where is that? thanks a million man.

 

There is a fuse in the fuse box for the fan relay coil supply, the motor supply is protected by a fusible link coming off the battery. Should be an orange wire with a red fusible link.

 

Actually, the sensor that is in the intake mainfold on the TBI cars is the temperature sensor for the computer. The switch for the coling fans is in the passenger cylinder head.

 

That's what I said.

 

It was late...I missed it.
