Is It Time for Service on My 2018 GMC Sierra 1500 Cooling System?

It can be tough to know when to have your GMC Sierra 1500 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. 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.

Staying on top of routine radiator maintenance for your 2018 GMC Sierra 1500 is essential for long-term engine health. To keep your radiator functioning, GMC recommends replacing your antifreeze or coolant at scheduled intervals but it’s also wise to keep an eye out for signs of a failing radiator. You might be driving around (or about to be stranded) with a failing radiator 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.

Common GMC Sierra 1500 Radiator Questions

With regular maintenance and service as needed, you could extend the life of your 2018 GMC Sierra 1500 radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • 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? 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.
  • When should my GMC Sierra 1500 radiator 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 1500 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • 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.
  • My Sierra 1500 radiator sounds like it's rumbling or boiling! What's up? Your Sierra 1500’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!
  • Is it bad to have rust on my Sierra 1500 radiator? Yes. Having rust in your GMC Sierra 1500 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.
