Your Optima is a prized possession.

Anyone who operates a Pontiac knows that when it comes to repairing their vehicle only the absolute best replacement parts will do.

The vehicle in your driveway is head and shoulders above the rest when it comes to all the cars, trucks, and SUVs in today's marketplace. Your Pontiac dealership isn't the only place to find genuine or original equipment quality repair parts to fix your Optima.

Why Thermostats replacement is so important.

Your car or truck uses liquid coolant to maintain a constant temperature in the engine, and the device that controls the flow of coolant so that the engine can remain cool is your thermostat. 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 the right temperature, your Pontiac Optima thermostat responds by directing coolant to the radiator. Now your coolant is part of a constant cycle in your Pontiac Optima engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.

You've tried the rest, now try the best.
