Ok, so here is the deal. My fans arnt comming on w/ or without a/c which I'm pretty sure is the cause of my coolant overflowing. I replaced all the relays (two 4 prong and one 5 prong) and the two fuses (the red 10a and the yellow 40a). Still nothing. So i hard wired my fans to my battery and sure enough both cooling fans work. So now i'm suspecting it's in the wireing somewhere any other ideas? or solutions on testing the wires?! i have NO idea when it comes to electrical.

Also I talked to a coworker of mine who was a dealer machanic for chevy for 4 years, he suggested it might be the Temperature sensor. Should I replace and how would i know if its working? (Im assuming its the temp sensor right by the 1st header opening)

thanks fellas

I would start with check all the harness for damage and grounds.

another thing....a couple of people have suggested that it might be my temperature sensor crapping out therefor the pcm never gets the signal to turn on the fans....but, they dont come on when i turn on the a/c either so wouldnt that rule out the temp sensor?

If you have a scanner or can get one plug it in and see what the temp sensor reads after it's warmed up. If you don't you should get a rough idea by your temp gauge on the cluster. If that's not the culprit you probably have a bad wire, connection, or short somewhere.

I'm thinking ill just put an slp fan switch on the ******, ive been wanting an excuse to get a new and better temp gauge anyway
