But the fans should come on. It varies a little by year but the primary fan should kick on at 226, secondary at 235. To check operation, just idle the car and watch the fans, they should come on at those temps. If your a/c is working (blowing cold), turn on the a/c at any engine temp and see id the fan(s) come on. Both fan relays are on the drivers side radiator shroud mounted side by side. The relays are engaged by grounding them (by the ECM). Check the wiring connector to them and pull the relays to check their connection. The circuit to both relays - the pink/black wire should be hot (key on). The grounding wires from the ECM are blue/white on one and green/white on the other. Also, at the fans, you should see 12v on the black/red or black/pink wire at the fan (a/c on, engine idiling) may be one or both fans with the a/c on. Yoou can also put in a manual switch to turn the fans on when ever you want but you have to have everything functioning correctly first. |
