When to Service Your 1999 BMW 740iL Cooling System

It can be tough to know when to have your BMW 740iL radiator serviced if you don't know what it does, 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 1999 BMW 740iL is a huge factor in the longevity of your engine. In fact, BMW recommends replacing coolant/antifreeze at specific intervals, but it’s also wise to keep an eye out for signs of a failing radiator. 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

With regular maintenance and service as needed, you could extend the life of your 1999 BMW 740iL radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • What does the coolant light on my BMW dashboard mean? If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.
  • What are the puddles in my driveway or garage floor? Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!
  • When should my BMW 740iL radiator be cleaned? To keep your BMW 740iL radiator running well, it’s wise to get it cleaned out a few times a year.
  • What is causing my 740iL to overheat? One of the main reasons your BMW 740iL engine might overheat is because you don’t have enough coolant. Other causes include a clogged radiator, a damaged cooling fan, a malfunctioning thermostat, or a faulty water pump.
  • My 740iL radiator sounds like it's rumbling or boiling! What's up? Your 740iL’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!
  • Is rust in my 740iL radiator bad? Yes. If you have rust in your BMW 740iL radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.
