Andrew,
The TEMPII sensor (blue) does NOT control the temp gauge. The gauge has
another sensor(black) that is located on the same coolant distribution
manifold as the TEMPII sensor.
They both can be swapped out with a "quick hand".

Subject: [VANAGON] Changing Temp II sensor

In an attempt to right my temp gauge read-out, I want to swap in a new
sensor on the t-stat.  Can this be done (with a quick hand) without
going back and bleeding the entire coolant system?

I DO intend to try cleaning the existing sensor connections first to see
if that fixes it.

Thanks,

Andrew
