Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
I have a 2006 H3 I just bought and replaced the leaking radiator, temp gauge is between 1/2 and 3/4 and OBII says 213F while running with ac on after driving over an hour, is that a normal temp or to high?
Whatever, my temp doesn't run to 213°F!
I recently checked the accuracy of the gauge.
Posted below, take note of my engine temp at startup was already @ 115°F(93°F ambient temp):

Indicator still points @ halfway mark, just to the upper part( scanner ect is the bottom line @201°F):

Yeah.... and your H3 is not his H3, is it?
It depends on many things, one of the most common reasons for an H3 running warm is a dirty radiator because somebody (current or former owner) just had to go mud bogging through big azzed dirty puddles.
Simple solution is to clean the radiator with a gentle spray of water. Might even use some mild soapy water on both front and back with thorough rinse.
