What does an illuminated coolant temperature light mean for my BMW?

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.

Is an antifreeze leak dangerous?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

My 330xi overheated! What can cause that?

If your BMW 330xi engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.

Why does the radiator in my 330xi sound like it’s rumbling or boiling?

Your 330xi’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!

There’s rust in my 330xi radiator. Should I be worried?

Yes. Having rust in your BMW 330xi radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure.

To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.

When to Service Your 2003 BMW 330xi Cooling System

It can be tough to know when to have your BMW 330xi radiator serviced if you don't know what it does, but it’s vital to know what to look for. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. 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 330xi is essential for long-term engine health. In fact, BMW recommends replacing coolant/antifreeze at specific 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 notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.
