Select Your VehicleYour GMC dealership isn't the only place to locate genuine or original equipment quality parts to repair your K25 Suburban. GMC car, truck, or SUV owners have come to expect a certain level of reliability when driving their K25 Suburban around town. Make no mistake, you bought your K25 Suburban because you knew that you wanted performance and rugged design both rolled up into one car, truck, or SUV. You bought your K25 Suburban because its dependability and longevity appealed to your senses; so why would you be okay with anything but the best when it comes to the highest quality auto parts?

Why Heater Core replacement is so important.

Before cars and trucks were built with the ability to cool their interiors, they had the ability to heat them. The engine of your GMC K25 Suburban circulates liquid coolant throughout the block to absorb heat, and sends this liquid to the heater core (a small radiator) through a heater supply hose when you want to warm your vehicle's cabin. This heater core is almost always installed on the passenger side of the firewall, and you can find a couple of hoses leading to it. To make a long story short, your GMC K25 Suburban heater core acts like a radiator; in that it uses the engine coolant to emit heat for the blower motor to propel into the inside of the car.

High quality parts, prices that won't break your bank, experienced automotive professionals.
