where does it go, i know there is supposed to be a ground there, but where does it go, there are no loose grounds anywhere, i can find, but there is a place to ground it at. can i just run a ground to the neg. battery terminal or the fire wall or something

 

Should be right beneath the rad hose....I know mine has coolant all over from the hose leaking a little bit.

 

beneath the rad hose? i see a place above it to put it. and also there are 2 ground wires that goto the side of the thermo housing. is this it?
