When to Service Your 2019 GMC Sierra 3500 HD 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 3500 HD radiator serviced. Nonetheless, 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 3500 HD is essential for long-term engine health. GMC recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an engine breakdown 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.

Questions About GMC Sierra 3500 HD Radiators

Take care of your 2019 GMC Sierra 3500 HD 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.
  • Is an antifreeze leak dangerous? 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 3500 HD radiators be cleaned? Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your GMC Sierra 3500 HD in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • What is causing my Sierra 3500 HD to overheat? If your GMC Sierra 3500 HD engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.
  • Why does the radiator in my Sierra 3500 HD sound like it’s rumbling or boiling? Your Sierra 3500 HD’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!
  • There’s rust in my Sierra 3500 HD radiator. Should I be worried? Yes. Rust in your GMC Sierra 3500 HD radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.
