2002 GA SE1 3.4 V6 cooling fans not working, overheats?

2002 GA SE1 3.4 V6 130,000 miles. This car is overheating. Cooling fans are not kicking on. (Even with the A/C on) Coolant comes out of the reservoir overflow hose. Here are the things I have done:

New Thermostat and new reservoir %26quot;pressure%26quot; cap

Bled air out of system.

Pressure tested system-holds PSI steady

Checked every fuse and swapped out every fuse at all 3 fuse/relay boxes.

Checked and OHMed the relays and also numbered and swapped their positions at the underhood fuse box/relay panel.



When I jump the #1 and #2 cooling fan circuits (relays) at the underhood fuse /realy block the fans will turn on and run.

When the temp guage hits about 220 the antifreeze pukes out the overflow hose and I did notice that the lower rad hose collapses and pinches shut.



So, do I have a bad PCM?? I know I need a new lower radiator hose (plan on changing upper also) Also, I am going to pull the water pump to inspect it.



If you have any other ideas please let me know!!



Oh, also I hooked up my code scanner to the car and it comes up clean.

might as well change out water pump because they're cheap. i was wondering what the coolant temp reads on the scan tool? maybe you have a bad temp sensor. also bleed system again to check for residual air pockets.
