My '94 has some cooling issues - doesn't get hot, gauge doesn't read temp., coolant is rusty brown, etc.
I needed to verify if the coolant sending unit was working because the gauge did not report temp changes before I order a new one. I found the sending unit by the alternator and pulled the wire off. It was the same after shorting out. The temp. gauge moves very slightly when I turn the key on. It did the same before & after shorting out. So it's partially working. Maybe I pulled the wrong sending unit??
So exactly how does it need to be shorted out? Wire to negative battery post??
Thanks!
