How To Know If Your BMW Radiator Has Malfunctioned

BMW alternators are generally quite reliable, but this doesn’t mean they can’t fail on you. The most common symptom of a failing BMW alternator is that your battery won’t charge, and the engine stalls if you turn the key to start it up. This guide will help you troubleshoot whether or not your BMW radiator has malfunctioned so you can get it fixed as soon as possible to avoid long-term damage to your engine and other components, like your headlights and windshield wipers!

Overheating Engine

An overheating engine is one of these signs of a malfunctioning BMW radiator. Typically, you can tell that your car’s engine is overheating if it stutters during acceleration or if it has difficulty idling. Other telltale signs include steam pouring from under your hood and water dripping from under your car’s hood.

Leaking Coolant

BMW coolant can be toxic to humans and animals. Ingesting it or coming into contact with it in any way can cause serious health problems, so if you see coolant leaking from your BMW radiator, don’t delay in fixing it. Turn off your engine immediately, then locate and fix the source of damage as soon as possible.

Shifting Issues

If you notice your car is shifting very stiffly, it could be a sign that your BMW Alternator Is Failing. Not only will it result in an uncomfortable ride, but if ignored for too long, it could cause further damage to other parts of your engine.

Low Coolant Levels

The coolant that circulates through your car’s radiator is what keeps your engine at an optimal temperature. As it does its job, it also circulates through your BMW alternator and refrigerant. This means if you’re seeing low coolant levels, it could be an indication that your BMW alternator has malfunctioned.

Fluid Discoloration

Although other issues can cause it, dirty engine coolant is usually a sign of an overheating BMW Radiator. Your car’s temperature gauge might also rise if your radiator is failing. But keep in mind that a discolored fluid isn’t always a sign of trouble—it can happen after you fill up with water and coolant from different sources. Ensure that there is no water in your radiator and that you have enough coolant in your reservoir.

Exterior Fins Blocked

Exterior fins blocked can happen due to dirt and another debris buildup. Cleaning these fins and surrounding areas will help prevent them from becoming clogged in the future. If you discover damage, you may need to replace your radiator. The exterior fins of your radiator play an important role in dissipating heat, so if they’re not working properly, your engine will overheat much quicker.

Sludge Build Up In Your Radiator

Oil and antifreeze mix to create a thick, syrupy substance that can clog your cooling system. Look for sludge and gunk build-up on your radiator. You might also notice steam coming from under your hood and your engine temperature spiking quickly. So if you see gunk anywhere in or around your radiator, it’s time to have a mechanic check out your cooling system immediately.

Passenger Heater Not Functioning

This could be a sign that your BMW radiator has malfunctioned. So if you’re experiencing an unexplained passenger-side heater failure, it’s definitely time to bring your vehicle in for an inspection.
