83 Degree High Flow Thermostat for Lower Coolant Temperature / Engine Temperature for Hummer H3 5.3

The task of a standard thermostat is to regulate the temperature of the motor and keep it within its ideal operating range to ensure the best performance and durability.

When the engine is cold, the wax inside the thermostat is solid and the thermostat remains closed, preventing coolant from flowing through the engine. As the engine warms up, the wax begins to melt and expand, opening the thermostatic valve and allowing coolant to flow through the engine. Once the engine has reached its optimum operating temperature, the wax in the thermostat will have fully expanded and the valve will remain open to maintain the desired temperature.

The wax thermostat is an efficient method of regulating engine temperature as it reacts quickly to temperature changes and can adjust the coolant flow accordingly. It is also durable and relatively low-maintenance, making it a popular choice for automotive applications.
