When to Service Your 1999 GMC Safari Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your GMC Safari radiator serviced, but it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 1999 GMC Safari is a huge factor in the longevity of your engine. In fact, GMC recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. You could be on the verge of a radiator-induced engine breakdown if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
