What does the coolant light on my Buick 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.

Is an antifreeze leak dangerous?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

When to Service Your 1991 Buick Roadmaster Cooling System

It can be tough to know when to have your Buick Roadmaster radiator serviced if you don't know what it does, but it’s vital to know what to look for. 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 1991 Buick Roadmaster is a huge factor in the longevity of your engine. To keep your radiator functioning, Buick recommends replacing your antifreeze or coolant at scheduled 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.
