Is It Time for Service on My 1990 Chevrolet G20 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Chevrolet G20 radiator serviced. Nonetheless, 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. 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 1990 Chevrolet G20 is essential for long-term engine health. In fact, Chevrolet recommends replacing coolant/antifreeze at specific 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 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.
