what is this too...jacked my stang up and it was sitting behide the passenger side wheel...where dose it go?

If that sensor was not installed coolant would be bubbling all over your engine while it is running.![]()

As others have said that is the ECT Sensor (Engine Coolant Temp). It goes in the hard heater lines where they come off the passenger side front corner of the intake manifold. Will your car run without it? yes but it will run rich. When I got my 88 it was missing the ECT because the yahoo who owned it before pulled the hard lines off the car when the heater core went bad and just plugged the threaded hole in the intake.

yeah I found all kinds of tools when i took the bumper cover off LOL

i have found an extending magnet arm + a 1/2 in socket, we should all get together and drive on a bumpy road to make some mod money. all kinda **** will fall out.I was once driving down the road in 65 and I heard something hit the road and when I looked in my rearview I could see my 1/2" wrench bouncing down the road.![]()
