You know that was my same thought i haven't done a block test but symptoms don't quite put me there for one i understand that if i have a warped head i would have milky oil or pressure in the cooling system but i don't have any of those symptoms


now let me bounce this off of you
the fans won't kick on until temp it's at a 225 degree mark and they come on in low speed now the pcm receives a signal from the coolant temp sensor then the pcm makes the fans come on depending on temp hi or low according to my scanner pcm it's getting the right signal but no hi fan speed and at 225 degrees so i'm thinking a new pcm or flashing it's in order


what do you guy think?
