GMC K25 Suburban Thermostats

Why you drive your K25 Suburban.

The vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles in today's marketplace. When your GMC K25 Suburban left the factory, it was destined for a person with discerning taste who prioritizes longevity in their automobile. You picked your K25 Suburban because its reliability and trusted quality struck a chord inside you; so why would you settle for second rate when it comes to superior quality auto parts? Auto enthusiasts appreciate the a brand you can trust built into each GMC, and understand that only the highest quality replacement K25 Suburban parts will suffice when maintenance needs to be done.

The function and purpose of Thermostats.

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 cycles the coolant through the engine block and gets it hot. Once it reaches an optimal operating temperature, your GMC K25 Suburban thermostat responds by directing coolant to the radiator. Now your coolant is part of a constant cycle in your GMC K25 Suburban engine that keeps it within a specific range of temperatures that are ideal for engine performance... all thanks to the thermostat.

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