Review on MotoRad 538-187 Integrated Housing Thermostat - 187 Degrees for Chevrolet Colorado, GMC Canyon, Hummer H3, H3T, Isuzu i-Series: A Reliable Temperature Control Solution by James Stjames

The standard thermostat heated my h3 to the last mark on the temp gauge. After several reviews I bought these and soon received them, you can tell the difference immediately. The motorcycle thermostat has an air vent in the center and not the original manufacturer's housing. Before installing I was able to remove the motorrad thermostat and move the hole on the top and line it up with the square (square) location. on the body means top) The reason for this is to remove air from the top of the engine. Now my Hummer x3 runs at the average mark, with the A/C on runs slightly above the average mark.
