Is It Time for Service on My 2002 GMC Sierra 2500 HD Cooling System?

It can be tough to know when to have your GMC Sierra 2500 HD radiator serviced if you don't know what it does, but it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 2002 GMC Sierra 2500 HD is crucial to keep your engine in the best possible shape for years to come. In fact, GMC recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

GMC Sierra 2500 HD Coolant Fluid Exchange

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your GMC Sierra 2500 HD cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

Radiator problems often go hand in hand with water pump problems. Some services for your 2002 GMC Sierra 2500 HD engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. This vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature. Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. From the heater core to the radiator cap, your 2002 GMC Sierra 2500 HD is in good hands at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
