Easy Coolant Temp Sensor Fix

[Mr. 250r]

A few of us are also running 91 gauges but what we did was just have your original temp sensor milled down to fit the passenger head i can't remember the size its in my suburban build thread i believe i figure that's the easiest solution

^^^ I did this on my '93 S-10 with 5.3L and it worked great for the 2yrs I owned it (17k miles) with zero issues. I thought that was the easiest solution as well.

I tried this as well. The sensor I tried it on did not have enough meat on it. By doing it with a potentiometer, I did not have to mill anything down. It took about 10 minutes to wire and adjust. And a potentiometer only cost $1.99.

This is the third truck I have wired. The first two we drilled and tapped the head. I did not want to do that on this one.
