Is It Time for Service on My 1988 BMW 735i Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your BMW 735i 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. 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 1988 BMW 735i is a huge factor in the longevity of your engine. To keep your radiator functioning, BMW recommends replacing your antifreeze or coolant at scheduled intervals but you can also take note of any signs your radiator is going bad. 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.

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your BMW 735i’s cooling system.

Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 1988 BMW 735i at Firestone Complete Auto Care. After all, we know it’s not just a car.
