Is It Time for Service on My 2020 GMC Sierra 1500 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your GMC Sierra 1500 radiator serviced. Nonetheless, it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. 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.

Regular, proactive service on the radiator in your 2020 GMC Sierra 1500 is essential for long-term engine health. 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 notice leaking coolant, overheating, or an illuminated low coolant dashboard light. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

What to Expect from GMC Sierra 1500 Radiator Repair

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your GMC Sierra 1500 cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 2020 GMC Sierra 1500 engine can wait, but the water pump is one part that you can't put off repairing or replacing. This vital part keeps coolant moving through the engine, hoses, and radiator. 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 help make sure everything is in working order. If you’re about to lose your cool over a too-hot engine, rest assured that we’re here to give your 2020 GMC Sierra 1500 the top-notch service it needs. After all, we know it’s not just a car. It’s your car.

Questions About GMC Sierra 1500 Radiators

Take care of your 2020 GMC Sierra 1500 radiator and it will last. Check out our top questions and answers about GMC radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • 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.
  • What are the puddles in my driveway or garage floor? Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.
  • Can GMC Sierra 1500 radiators be cleaned? To keep your GMC Sierra 1500 radiator running well, it’s wise to get it cleaned out a few times a year.
  • What can cause my Sierra 1500 to overheat? Your GMC Sierra 1500 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 1500 radiator sound like it’s boiling or rumbling? Air pockets in your Sierra 1500’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.
  • Should I be concerned about rust in my Sierra 1500 radiator? Yes. Rust in the radiator of your GMC Sierra 1500 can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.
