Is It Time for Service on My 2003 BMW 745i Cooling System?

It can be tough to know when to have your BMW 745i radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. 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.

Keeping up with regular radiator maintenance in your 2003 BMW 745i is essential for long-term engine health. BMW recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. Your radiator could be close to causing an 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.

Radiator Repair Service for Your BMW 745i

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your BMW 745i cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Some services for your 2003 BMW 745i engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. This vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature.

If you’re about to lose your cool over a too-hot engine, rest assured that your 2003 BMW 745i is in good hands at Firestone Complete Auto Care.
