Temp guage accuracy?

My dash guage stays at the middle of the "E" after warming up without
the radiator fan being connected.After driving today 55* outside temp
for 10 miles at 65mph it still didn't go much above the middle of the
"E" even after shutting it off.It does go to O when cold and does move
to the "E" when warm but no further.I had the head replaced and don't
want to have it fail because the guage is faulty.

Might help if you tell us what car you're driving. And maybe where you
are, because 'round these parts, there is no "E" or "O" on the
temperature gauge. It's "C" for Cold and "H" for Hot.

Sorry,1988 626 auto non turbo 4dr USA model.
The guage has T.E.M.P and the needle sits dead on the middle of the "E"
Some one suggested pulling the wire off the sender and grounding it to
the engine but there are TWO sending units on the thermostat and even
pulling them off but not grounding the guage still reads on the "E"
Can't find anything in the MAZDA shop manual about these senders or a
quick check other than removing and doing a resistance check,which I
don't know how to do.

I take it then that the "T" is at or near the "hot" line and "P" is at
or near the "cold" line? If so, then it sounds like it's either
running warm, perhaps close to tolerance, or the thermometer's broken.

I believe a "resistance check" is, with power off, run an ohm meter
across the circuit. It will show a resistance value in ohms that you
can compare to the specs.

NO,actually the exact opposite.T is at the COLD side the "E" is below
the mid point.
