What do you guys think

Okay my cooling fan wont come on. I took the radiator out to see if it was plugged, I filled it with water and it was coming out of the bottom. I replaced the thermostat and still nothing so my only other option is one of the sensors on the bottom of the radiator or the fan motor is bad right.

Check the sensors, and check the wiring. Do you have a logger?

I think you will get more responses with a more informative thread title

Feed some power to the fan motor, swap out some relays for known working ones, check all fuses, wiring, etc. and like Doc says, if you have a logger give it a shot.

Can i turn on the fan with the logger? I didnt see it on there cuz I was gonna try it. I swapped a relay out and still nothing. Can I just put an electric fan in and let it run all the time or put it on a switch and call it good?

Are you 1st or 2nd gen?

[whitedevilstealth]

first gen with the sensors on the radiator

Copy and paste of a post from the other site:
-------------------------------------------

Alright... I'll throw in a quick rundown of how 1st gen system works.

There are five relays. A high and low speed relay for each fan, and a radiator fan control relay that turns the low speed radiator fan on with the A/C.

The radiator fan changes speed by running resisted power to the motor for low speed, and unresisted power for high speed. the condenser fan actually has two sets of windings, so it is in effect two separate motors and circuits.

There are two thermo-switches, each for high or low speed, the low speed switch only turns on the radiator fan, the high speed switch turns on both fans.

When the A/C is turned on, the condenser fan low speed is engaged(the only time that circuit is used) and the radiator control relay grounds the same circuit as the low speed thermo switch, turning on the radiator fan at low speed.

Now that you're thoroughly confused... Study the wire diagram and it should all make sense.

Yes, you can test the fan with the logger, you can also check the temperature that the ECU sees.

lol, I sat on this page for like ten minutes, mb.

How do I test the fan with the logger? I went through the test part on my palm and didnt find anything for the fan only pump,purge,egr,boost,pres-re( whatever that is) , mvic andinjectors

You can't on a 1st gen... The ECU has no clue what's going on with the fans, they're entirely controlled by thermo switches. Only 2nd gen fans are controlled by the ECU.
