Keeping your K25/K2500 Pickup in top shape is your top priority.

Obviously, you didn't buy your K25/K2500 Pickup unless you knew that you wanted horsepower and great value both rolled up into one car, truck, or SUV. The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles in today's marketplace. While it's not hard to find replacement parts for GMC vehicles, these days only the highest quality are required to maintain your automobile. Anyone who owns a GMC knows that when it comes to maintaining their car, truck, or SUV only the most superior replacement parts will do.

The function and purpose of Coolant & Radiator Hose.

Car or truck motors must stay within a certain operating temperature if they are going to stay running. That's why your GMC K25/K2500 Pickup engine has a network of radiator and coolant hoses transferring 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 direct coolant through the thermostat housing, heater core, and the coolant reservoir. If a GMC K25/K2500 Pickup radiator or coolant hose gets a leak, then coolant pressure will drop and it could boil; leading to engine failure.

We carry all the top brands.
