When Does My 2015 GMC Sierra 3500 HD Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your GMC Sierra 3500 HD radiator serviced, but 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.

Keeping up with regular radiator maintenance in your 2015 GMC Sierra 3500 HD is a huge factor in the longevity of your engine. To keep your radiator functioning, GMC recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

What to Expect from GMC Sierra 3500 HD Radiator Repair

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your GMC Sierra 3500 HD 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.

Radiator problems often go hand in hand with water pump problems. Of all the parts in your 2015 GMC Sierra 3500 HD engine, the water pump is one that you'll want to have repaired or replaced as soon as you discover a problem with it. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. Without it, your engine won't maintain its optimal temperature. Our trained technicians can inspect your car’s radiator hoses and pumps to help you stay ahead of any potential engine problems. If you’re about to lose your cool over a too-hot engine, rest assured that your 2015 GMC Sierra 3500 HD is in good hands at Firestone Complete Auto Care.

Questions About GMC Sierra 3500 HD Radiators

Wondering how to make your 2015 GMC Sierra 3500 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.

  • What does an illuminated coolant temperature light mean for my GMC? If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.
  • What are the puddles in my driveway or garage floor? It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.
  • Can GMC Sierra 3500 HD radiators be cleaned? It could be a good idea to have your GMC Sierra 3500 HD radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • My Sierra 3500 HD overheated! What can cause that? 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? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Sierra 3500 HD. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Is rust in my Sierra 3500 HD radiator bad? Yes. Rust in the radiator of your GMC Sierra 3500 HD 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.
