When to Service Your 2017 GMC Sierra 3500 HD Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your GMC Sierra 3500 HD radiator serviced, but you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Keeping up with regular radiator maintenance in your 2017 GMC Sierra 3500 HD is a huge factor in the longevity of your engine. GMC recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You could be on the verge of a radiator-induced engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Issues with your radiator often coincide with a malfunctioning water pump.

This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it’s not working well (or at all), your engine can easily overheat. Our trained technicians can inspect your car’s radiator hoses and pumps to help you stay ahead of any potential engine problems.

  • Do GMC Sierra 3500 HD radiators need to be cleaned? To keep your GMC Sierra 3500 HD radiator running well, it’s wise to get it cleaned out a few times a year.
  • What is causing my Sierra 3500 HD to overheat? Your GMC Sierra 3500 HD engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • My Sierra 3500 HD radiator sounds like it's rumbling or boiling! What's up? There could be air pockets in your Sierra 3500 HD’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
  • Is rust in my Sierra 3500 HD radiator bad? Yes. Rust in your GMC Sierra 3500 HD radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure.
