Is It Time for Service on My 2003 Buick Regal Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Buick Regal radiator serviced, but it’s vital to know what to look for. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. When the radiator isn't working properly, your engine can overheat and potentially break down.

Regular, proactive service on the radiator in your 2003 Buick Regal is essential for long-term engine health. 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 might be driving around (or about to be stranded) with a failing radiator 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.

Buick Regal Coolant Fluid Exchange

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Buick Regal cooling system.
