Great cars and trucks like your Sierra 3500 Classic need great parts.

GMC automobile owners have become used to a certain level of reliability when driving their Sierra 3500 Classic around town. The vehicle in your driveway is head and shoulders above the rest when it comes to all the cars, trucks, and SUVs currently being driven today. Anyone who operates a GMC knows that when it comes to maintaining their car, truck, or SUV only the most superior replacement parts will do. Your GMC dealership isn't the only place to buy genuine or original equipment quality parts to repair your Sierra 3500 Classic.

Why Thermostats replacement is so important.

Your car or truck uses liquid coolant to maintain a constant temperature in the 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 the right temperature, your GMC Sierra 3500 Classic thermostat then opens up and allows the coolant into the radiator. Now your coolant gets cooled as it recirculates through your GMC Sierra 3500 Classic 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.
