Thanks guys.

Here's the latest experiment, we had co-operating weather here.

With everything else the same, I drove for 30+ minutes on highway to see
where the needle ended up stable.

Yesterday it was 55F outside, and the temp is approx 197.
Today it was 81 outside, and the temp is approx 229 (vertical needle).

The 914-6 gauge only has a few numbers, hidden, but especially vertical is
right on one of them.

So, I think that cooler must be blocked or something.
