I have installed a new instrument cluster in my '84 Grand Wagoneer, due
to the original having burned up in a fire.

Everything is installed and appears to be functioning; however, my H2o
temp is well below the green arc, and my oil pressure runs at about
25-30 psi. It might reach 38 psi when cold, but I'm worried about it
being that low all of the time. It doesn't seem to change with
temperature. We've had zero-degree weather the last few weeks and now
it's up in the 40s (F). I am running Castrol 10-30 oil.

As always, any suggestions, advice, etc., very much appreciated.
