When to Service Your 2016 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.

Regular, proactive service on the radiator in your 2016 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 a good idea to keep your eyes open for any indication that your radiator is failing.
