Your car or truck has a water-cooled motor, and its thermostat keeps the coolant flowing in the right direction so that your engine can maintain a constant and ideal operating temperature. On start-up, the thermostat remains closed; shutting off access to the radiator. This gets the coolant hot so that the engine warms up. Once it reaches an optimal operating temperature, your Pontiac Optima thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your Pontiac Optima engine that keeps it within a specific range of temperatures that are ideal for engine performance... all thanks to the thermostat.
