Have a 90 lumina euro w/3.1 V6 w/134000km (83000mi). It sat for over a
year until I replaced the trannie, now I am using as my commuter to work
The scale on the temp gauge is 40C(104F) on the bottom and 125C(257F) on
top. That means that the middle of the gauge is 82.5C(180.5F). Once
warmed up, the gauge usually reads at between 1/4 and 1/2, translating to
about 65C - 72C(152F - 161F).
I usually drive imports, where the temp of the engine is at least 180 once
fully warmed. What is the running temperature of my Lumina supposed to
149F seems too low....
The temp doesn't fluctuate at all once warmed up, which kinda rules out
sticky thermostat. I am located in Canada, current ambient temperature is
-25C(-13F), and the car is not throwing great heat.
I am thinking of replacing the thermostat with a higher temp (180F), what
does everyone recommend? Anyone see any potential problems with doing
this? Will I create leaks if there is a weakness in the cooling system?
