Cooling problem, My fan wont turn on.
 

I spent pretty much the whole day fixing a few bugs on the engine, the engine runs great, but I cant figre out why my fan wont turn on, so far I have:

Jumped the fan relay to make sure it works, it does.

Used a different relay, I used the one out of my sedan and I know that one works.

Switched the 2 wire sensor on the water neck again from the sedan.

The only thing I did not change (and I have a feeling this is it) is the 1 wire sensor that goes in to the head, is this the sensor that activates your fan? or the one that displays your temperature on you cluster?

If any of you know what else would cause your fan to not run, please let me know.

3 temp sensors.

1. below dist is for the ecu
2. below dist as well is for the cluster
3. rad fan switch, near oil filter / oil line feed ;)
or
3. some cars have this 3rd switch in the thermostat housing.

if you unplug that and ground it, the fan should come on. (i think :l )

have fun
