hi all. I just bought a 87 TII here in quebec ( not easy to find here) I have a green sensor just behind the prestone fill cap with no wire on it ??



do you have any idea what is it ?



thanx

dunno, the bac valve is on the right hand side of the upper intake manifold, there is a little coolant hose running thru it.

green sensor behind the fill cap, would that be on the engine or on the radiator?



if it's on the engine, you're probably referring to the coolant temp sensor, which threads into back side of the water pump housing.

Got a pic?

it is on the passenger side of the engine bay next to the intercooler near. It is cylindrical, has coolant hose going to it.



It also says denso on it.

i send some pix tonight



thanx
