    Sep 19, E90 electric water pumps tend to have a relatively short life span, and if and since they are a little tricky to replace, can cost a huge amount of.

    When maintained, your BMW's cooling system should be bulletproof. The weakest link on any BMW model is likely to be the water pump, thermostat, or electrical.

The composite impellers have proven themselves for over a decade as a trouble-free and efficient design and many of the OEM suppliers are also introducing updated composite designs for older models too. Just got the car back today morning.

    The water pump, also known as the coolant pump, circulates coolant through the engine's cooling system. The water pump pushes coolant through a vehicle's cooling system. The water pump is driven by an accessory belt at the front of the engine or by the timing belt, or by the timing chain. Water pumps require replacement if they begin to leak coolant or become noisy. Leaking water pumps can result in damage to the drive and timing belts, as well as cause the engine to overheat.

    A failed water pump can be caused by other problems in the cooling system, such as a failing thermostat, radiator, or head gasket. A worn water pump has far reaching effects. If the water pump is not maintaining proper coolant circulation the engine will overheat, causing leaks, possible head gasket damage, and ultimately a failed motor.

    Failure to shut down an engine while overheating will eventually cause stalling, necessitating a tow. Repair intervals vary greatly by vehicle and driving conditions. The water pump does not wear like a tire or a ball joint, but eventually the bearing or impeller can fail in the pump. When noisy, leaking, or unable to properly circulate coolant, the water pump needs to be replaced.

    The technician will check for leaks and wetness around the water pump area. With the engine running, they may also use a stethoscope to check for noise indicating wear of the water pump bearing. If visible, the belt driving the pump will be inspected, along with the water pump pulley to be sure the pump is being driven properly.

    In the case of electric water pumps on some newer cars, the engine's computer will be checked for codes, and the relevant tests will be performed to determine the proper repair. To replace the water pump, the cooling system is drained and the fan belt or timing belt and pulleys are removed. If the water pump is operated by a fan belt, the hose going from the water pump to the radiator is removed, as are the bolts securing the water pump to the engine. The water pump is removed from the engine, and the engine surfaces are cleaned.

    A new water pump and gasket are installed, and the cooling system is refilled with fresh coolant. If the water pump is operated by the timing belt, the timing belt covers, timing belt, and all related components are disassembled.

    The hardware securing the water pump to the engine is removed, and the water pump is removed from the engine. The surfaces are cleaned and a new water pump and gasket are installed. All timing belt—related components, fan belts, and pulleys are installed, and the cooling system is refilled with fresh coolant.

    Be sure to follow the specific procedures for your vehicle. Proper gasket handling, torque specs, and sealant usage are necessary for an effective repair. When refilling the cooling system, the manufacturer recommended coolant should be used. There are many bearing noises that could come from an engine bay. Proper care should be taken to diagnose them. The entire cooling system—including all of the coolant hoses and fittings, radiator, coolant fan s , and fan clutch if equipped —should be inspected when replacing the water pump.

    To help prevent future issues, we recommend replacing the thermostat when the cooling system has been opened for repairs e. The fan clutch may also be removed to access the water pump, and should be replaced if worn or leaking. When replacing the water pump, the drive belts may need to be removed, they should be replaced if worn.
