What does the coolant light on my GMC dashboard mean?

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.

When to Service Your 1986 GMC G2500 Cooling System

It can be tough to know when to have your GMC G2500 radiator serviced if you don't know what it does, but it's still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 1986 GMC G2500 is essential for long-term engine health. In fact, GMC recommends replacing coolant/antifreeze at specific 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.
