When to Service Your 2022 BMW 740i Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your BMW 740i radiator serviced. Nonetheless, it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. 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 2022 BMW 740i is essential for long-term engine health. BMW recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You could be on the verge of a radiator-induced engine breakdown 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.
