    The maximum towing capacity of the H3 SUV is 4500 lbs. The maximum towing capacity of the H3T short bed, crew cab pickup is 4400 pounds. Changing to a cooler temperature thermostat will make the engine run cooler; but you may have to search around to find a cooler thermostat that will fit your motor. The 3.7 liter I-5 was also used in the GMC Canyon; which may have more easily accessed thermostat listings. You'd have to ask a dealership whether 3/4 up on the gauge is normal for this model.
