Hey guys, I have read tons of posts on this subject but have yet to solve my problem. I bought my camaro a few years ago and the guy put in a vortec 350. Now with that said he had the fan set up to run all the time. So I have been trying to figure it out. He grounded the grn/ wht wire at the relay. But now I have noticed there's no fan pressure switch need help!!!!!

 

Go down to your favorite parts house and buy a fanstat/fanswitch in the temp range you want, look around here there's a few lists, find a plug/port the right size in the cooling sys, factory went with one in the right head (not positive the vortecs have it), remove plug, install fanstat, grab ground wire from the relay and run it to the fanstat (they are a switch to ground), done. Unless you have A/C in which case you need to figure out how to make the fan come on when the A/C is on.
