Is It Time for Service on My 1990 Buick Riviera Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Buick Riviera 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.

Regular, proactive service on the radiator in your 1990 Buick Riviera is crucial to keep your engine in the best possible shape for years to come. In fact, Buick 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 see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.
