When Does My 1984 GMC Jimmy Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your GMC Jimmy radiator serviced, but it’s vital to know what to look for. 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.

Staying on top of routine radiator maintenance for your 1984 GMC Jimmy 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. Your radiator could be close to causing an 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.
