I just got this car 02 GT 3.8. I did the normal since there were signs of leaks at the plentum. Things I did so far.
Changed the LIM gaskets to the new metal ones. Valve cover gaskets. Complete new upper plentum. Coolant temp sensor, Radiator, Water pump, Plugs ,wires,and air filter.
Car runs great no leaks good heat and bled the system a few times. Good heat and tstat is working fine.
The cooling fans DO work I checked them directly to the battery. Checked all fuses and relays and wiring behind fuse block. My fans do not run when I unplug the ECT, they never come on. I know they are supose to come on as a default when this is unpluged but they don't. The AC does not work at this time (that is next on the list) so I can't check it with the AC on.
I did notice that someone has probed the wires at the connector down by the fans and the radiator was replaced but not by me . The low coolant sensor I belive is faulty because the light comes and goes so I just unplugged it.
I have searched for 2 days on the forums but I haven't found a solution if the fans don't come on with the ECT unplugged.
I am leaning twards a ECM but...
I also did the upgrade for the blower motor cover under the cowl since the pass floorboard was soaked with water.
All help is appreciated. Thanks
