GMC K15 Coolant & Radiator Hose

Why you drive your K15.

GMC automobile enthusiasts have become used to a certain level of reliability when driving their K15 around town. Obviously, you didn't buy your K15 unless you wanted to buy horsepower and rugged design both rolled up into one automobile. Anyone who operates a GMC knows that when it comes to fixing their car, truck, or SUV only the absolute best replacement parts will do. Your GMC dealership isn't the only place to find genuine or original equipment quality parts to repair your K15.

What Coolant & Radiator Hose does for your vehicle.

Engines need to keep cool if they are to maintain operational status. That's why your GMC K15 engine has a network of cooling hoses transferring a mixture of water and ethylene glycol throughout the engine. The radiator hoses under your hood connect the water pump and engine block to the radiator core, while other coolant hoses send the ethylene glycol mixture through the thermostat, return the coolant to the expansion tank, or by-pass the heater hose flange. If a GMC K15 radiator or coolant hose springs a leak, then the motor will not be able to cool itself and the temperature will increase; leading to engine failure.

We've got what you are looking for.
