mechanical water temp gauge not working.

[Johnny Blaze]

My truck has a set of summit gauges. They are the classic, autometer looking ones.

Mechanical.

Yesterday I change my heater hoses, well actually I rerouted one to feed my clifford intake.

Afterwards, I started the truck checked for leaks, and drove it around. Gauge worked fine, no leaks.

Came home, toped of radiator.

This morning I get in it, and take off for work. I am pretty sure I saw the gauge start to rise at first.

But, once I got going it never came off 100.

Now my drive is about 10 minutes, and I even got on it a few times.

But the gauge never moved.

I got out, checked the radiator cap, it had pressure in the system.

Looked at the tubing, and it did not look like it had been disturbed or damaged.

Any ideas?

After the truck has set for about 20 minutes, the gauge has still not moved.
