The Hummer Thermostat maintains the correct engine temperature to ensure that every adventure begins and finishes without the engine getting overheated. Hummer enthusiasts are fond of the fact that the elevated ground clearance, heavy duty suspension, and progressive four wheel drive allows the SUV to navigate even the rocky terrain, muddy paths, yet afford passengers spacious seating and expansive views that inspire confidence anywhere they go. The car is the result of a 1990s military concept that combines brute strength with minimalist dashboard features and bright screens that have essential terrain data in full view. All Hummer owners understand that even grade stable cooling is as significant as torque during steep grades. A Thermostat is a spring-loaded valve which detects the heat in the coolant and may or may not be opened to the radiator allowing the engine to be warmed up in the short possible time and thereafter maintain the required temperature. To fit the Thermostat, allow the engine to cool, loosen the cap then drain sufficient coolant until the housing is dry. Unclamp the top hose, remove the housing bolts, mark the orientation of the old unit, pick it up together with its gasket and clean the lip so as to fit the new Thermostat into place. Install the new valve the same way, install a new seal, clamp the cover in place, re-attach the hose, fill the coolant, squeeze the hose to expel all the air, start the engine, and observe the temperature gauge to ensure correct warm up and leakage. Whatever is stable, your reliable Hummer is on its way to the next path.
