i replaced that temp. sending unit that comes out of the rotor housing or block right under the oil filter and the gauge sitll does not work... we looked in the book and we learned how to do the check and we did it and it worked. so there is still more digging to do oviously so if anyone could help me... (Pengaru get on this lol or i'm gonna call you) cause i need to figure out if my car is still running hot or not.
