Tips to Deal with a BMW Water Pump Failure
BMW water pumps are designed to circulate coolant throughout the engine to keep it operating at the ideal temperature. The water pump is driven by a belt that is connected to the crankshaft, and as the belt turns, the impeller inside the pump begins to spin. This action creates suction that pulls coolant from the radiator and into the pump.
From there, the coolant is pushed through the engine block and back into the radiator, where it can be cooled. BMW water pumps are built to last, but they can eventually fail due to wear and tear. When this happens, it’s important to have the pump replaced as soon as possible to avoid engine damage. BMW recommends that the water pump be replaced every 50,000 miles or when needed to ensure optimal engine cooling performance.
Coolant Leaks, Low Coolant Levels, and Engine Overheating
One of the most common BMW water pump failure signs is coolant leaks. Look for wet spots on the ground under your BMW, as well as for low coolant levels in your BMW’s radiator or overflow tank. check the door, hood, and trunk seals for leaks as well.
Another sign of a failing water pump is engine overheating, especially during city driving when the BMW is idling in traffic. The BMW’s water pump circulates coolant through the engine to keep it at operating temperature, so if it fails, the engine will eventually overheat.
Also, listen for abnormal noises coming from your BMW’s engine compartment. A failing water pump may make a grinding or whining noise. If you notice any of these BMW water pump failure signs, have the BMW towed to a nearby service station for repair.
Why did my BMW’s water pump fail?
BMW is known for their luxury sports cars, but you have to have a professional mechanic on call if one of the parts fails. Since the water pump is an essential component in BMW’s cooling system, a failure can cause major engine damage. There are several causes of water pump failure, but the most common are listed below:
- Impact with a foreign object: A foreign object such as dirt or debris can get caught in the water pump and cause it to fail. BMW recommends flushing the cooling system regularly to prevent this from happening.
- Poor quality coolant: BMW recommends using only BMW-approved coolant in their vehicles. Using other types of coolant can cause the water pump to fail.
- Over taxing the engine: BMW engines have a tendency to overheat, which can cause the water pump to fail. BMW recommends keeping an eye on the temperature gauge and taking breaks frequently when pushing the engine hard or when in hot weather.
- Leaks: A coolant leak can cause the water pump to fail. BMW recommends checking the coolant level frequently and adding coolant as needed.
If you suspect that your BMW’s water pump has failed, it is important to take it to a certified BMW dealer or mechanic for repairs. Attempting to fix it yourself could void your warranty or cause further damage.
