When to Service Your 2006 GMC Sierra 3500 Cooling System

It can be tough to know when to have your GMC Sierra 3500 radiator serviced if you don't know what it does, but it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 2006 GMC Sierra 3500 is essential for long-term engine health. In fact, GMC recommends replacing coolant/antifreeze at specific 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 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.
