Is It Time for Service on My 2019 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. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Keeping up with regular radiator maintenance in your 2019 GMC Sierra 2500 HD is crucial to keep your engine in the best possible shape for years to come. 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. Your radiator could be close to causing an 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.

Radiator Repair Service for Your GMC Sierra 2500 HD

What’s included in a radiator repair service? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your GMC Sierra 2500 HD. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 2019 GMC Sierra 2500 HD engine that you'll want to have repaired or replaced as soon as you discover a problem with it. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. If it’s not working well (or at all), your engine can easily overheat. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. From the radiator cap to the heater core, your 2019 GMC Sierra 2500 HD is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Questions About GMC Sierra 2500 HD Radiators

Wondering how to make your 2019 GMC Sierra 2500 HD radiator last as long as possible? Read on for answers to common questions, and visit your local Firestone Complete Auto Care when your engine shows any signs of a faulty radiator.

  • Why is the coolant light on my GMC dashboard on? Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.
  • Can an antifreeze leak wait? Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!
  • Do GMC Sierra 2500 HD radiators need to be cleaned? It could be a good idea to have your GMC Sierra 2500 HD radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • Why is my Sierra 2500 HD overheating? Your GMC Sierra 2500 HD engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.
  • What is making my Sierra 2500 HD radiator sound like it’s boiling or rumbling? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Sierra 2500 HD. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Is it bad to have rust on my Sierra 2500 HD radiator? Yes. Having rust in your GMC Sierra 2500 HD radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.
