[Fot] Faulty Water Temp Gauge?

Hello All: 


Need some opinions on what I think might be a problem with my 1969 TR6 water 
temp gauge is an electrical unit. Scenario: recently, I've noticed the car 
running a bit hot, ie, the needle within an 1/8" of the red zone on the gauge. 
I recall at normal operating temp, the needle should be closer to half way 
(ambient daytime temps in the 80 - 90 degree range). Once the needle reaches 
this "hot" location, it never seems to come back down at all, regardless of 
whether I'm at speed or stopped. To me, this is not normal. 


What I've done so far: flushed the cooling system, filled with about 35% 
anit-freeze, remainder with distilled water; added a few ounces of Water 
Wetter; new temp sensor, new thermostat (180 degree), timing checked and spot 
on. So far no difference in the way the gauge reacts, indicates the engine is 
still running hot so I'm wondering if I might have a gauge going bad. Anyone 
have an experience with a faulty water temp gauge? Does it gradually go bad and 
give false readings? Thanks.
