Cadillac STS Thermostats

Keeping your STS in top shape is your top priority.

Auto enthusiasts know that luxury is built into each Cadillac, and know that only the best replacement STS parts will suffice when maintenance needs to be done. The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles in today's marketplace. You picked your STS because its a reputation for strength and unique styling appealed to your senses; so why would you settle for anything but the best when it comes to the highest quality auto parts? Cadillac automobile enthusiasts have become used to a certain level of a reputation for strength when driving their STS around town.

Why Thermostats replacement is so important.

Your car or truck has a liquid-cooled engine, 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; bypassing the flow of coolant through your radiator. This cycles the coolant through the engine block and gets it hot. Once it reaches an optimal operating temperature, your Cadillac STS thermostat responds by directing coolant to the radiator. Now your coolant gets cooled as it recirculates through your Cadillac STS engine; keeping it within a specific range of temperatures that are determined for the engine to achieve the best balance between power, fuel efficiency, and emissions... all thanks to the thermostat.
