I have a 92 camaro RS 305 TBI. Fan only comes on when the AC is on. Car allways heats up to 240 or higher. Iam going to install a new 160 stat. Radiator 3 months old, just flush it. I feel that i need to put in a manual fan toggel switch to keep it cool for the summer. I found a connecter box passenger side next to the radiator that has a wire going to the battery plus 3 other wires, 2 going to the fan. Can i try to hook up a switch with the battery wire and the 2 other wires going to the fan. If not than how do i install a manual fan switch.

Kyle, You've got mail....

 

I also want to know how to install the manual switch.

 

Compliments of Willie:
Manual Fan Turn-on
Locate the factory fan relay. It has the following wires: Orange, black/red, tan/white and green/white. Splice (do not cut) into the green/white wire with a new section of 18-gauge wire. In other words, “tee” into the existing green/white wire. Connect the new wire to a toggle switch. Ground the other switch connector. The fan will now turn on with the switch as long as the ignition switch is on. A lighted switch can be used, but it complicates the wiring slightly.
NOTE
If a lighted toggle switch is used, do NOT follow the wiring instructions supplied with the switch. We are using it in a grounding circuit, not a power circuit (as the instructions infer), so wiring will be different. Installation of this switch is not recommended for the novice without a digital multi-meter.
“Fan On” LED
Splice (tee) a 22-gauge multi-stranded wire into the 12-gauge black/red wire at the existing fan relay. Connect this wire to the positive lead on the LED and ground the other LED lead.
NOTE
If a 2.2-volt LED is used, a ¼-watt, 680-ohm resistor must be wired in series with the LED (positive or negative side).

Hope that helps dude!

 

thanx a lot brothers! :lala: :lala: :lala:

 

My plug that plugs into the fan switch has broke. Could I use that wire and hookup a toggle switch instead of splicing into the relay for a manual fan switch.

Okay, where do i find the fan relay on my vehicle? 1988 firebird trans am, 5.0 L L03 TBI engine.

 

Fan relay is next to the radiator on the battery side on early models. Late models have the fan relay on the driver side Firewall behind the EST module (there will be 2 identical relays).

 

Found the relay. It was the one farthest over on the driverside firewall. Replaced it.

Now, the fan still does not run unless the air conditioning is on. Worse is that even with the air conditioning forcing the fan motor on, I am still running hot. Not overheating, but running hotter than I should. The temp gage reads 240 degrees.

So now what do I do?
