Posted: Mon Sep 30, 2013 11:47 amYeah It gets hot enough to where theres steam in the over flow tank
Posted: Mon Sep 30, 2013 10:32 pmwhen you say fan switch you mean the one on the thermostat housing correct?
Posted: Mon Sep 30, 2013 11:39 pmYes that one and it still won't come on
Posted: Tue Oct 01, 2013 4:27 amWait, you said in your first post that if you jumped it that it WOULD work? I'm confused

Posted: Tue Oct 01, 2013 7:19 pmThere is a coolant switch and a coolant sensor. The switch is under the distributor and only has one wire going to it. I believe you replaced the coolant sensor.

Theres a temp sending unit that controls the temp gauge. located under the distributor. one wire connector
Theres a ECT sensor that tells the ECU what the coolant temp is. located under the distributor. two wire connector.
and theres a fan switch. Located on the thermostat housing. also a two wire connector.
Maybe the ECT sensor is bad and the ECU thinks the engine is at normal temp and not telling the fans to kick on.
If you have a spare one, swap it out and see if it helps. I would suspect a code 6 to be thrown if the ECT sensor was in fact bad.

Not COMPLETELY wrong
More like spitballing leads. Too lazy to refresh my memory with the Helms when the OP could do it themselves.
Thanks for correcting the info!
Posted: Wed Oct 02, 2013 11:24 pmI beg to differ, but sure!

Posted: Fri Oct 04, 2013 9:44 pmMaybe try swapping relays out...
Or just wire it to a switch. or wire it to be on all the time.
I did a quick search for "steam out of overflow" and a lot of threads and answers so the headgasket is blown.
