Pontiac Optima Thermostats

You enjoy taking care of your Optima.

Select Your VehicleAnyone who owns a Pontiac knows that when it comes to maintaining their vehicle only the absolute best replacement parts will do. When your Pontiac Optima left the factory, it was destined for a person with discerning taste who values an American name in their automobile. Obviously, you didn't buy your Optima unless you wanted to buy horsepower and great value both rolled up into one automobile. Pontiac vehicle drivers have come to expect a certain level of dependability when driving their Optima around town.

What Thermostats does for your vehicle.

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.

High quality parts, bargain prices, staff that want to please you.
