Buick car, truck, or SUV owners have become used to a certain level of dependability when driving their GS around town.

Your Buick dealership isn't the only place to find genuine or original equipment quality repair parts to fix your GS. Auto enthusiasts appreciate the value built into each Buick, and understand that only top quality replacement GS parts will suffice when repairs are needed.

Don't go too long without fixing your Thermostats... here's why.

Your car or truck has a liquid-cooled 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 cycles the coolant through the engine block and gets it hot. Once it reaches the right temperature, your Buick GS thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your Buick GS engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.

What we have to offer.
