BMW's cooling system has long been a known weak spot, with the water pump and thermostat being two of the most common trouble areas. This remains true even in the latest B-Series engines found in 2016 and newer BMW models. This kit includes a brand-new OEM Pierburg water pump, a Bremmen thermostat (now referred to as a Heat Management Module), and one gallon of BMW's G48 coolant concentrate (enough to make two gallons of 50/50 coolant). Avoid spending thousands at the dealership or over $600 on Genuine BMW parts! These components can be replaced with high-quality OEM parts in just an afternoon using basic hand tools.

The water pump in your vehicle keeps all that coolant flowing freely. If it begins to fail, overheating problems are inevitable. Don't take a chance on doing damage to engine internals by not replacing your water pump. This has been a common problem amongst most German vehicles. Water Pump failure can lead to your vehicle making an unnecessary trip to the repair shop. If your pump stops working, coolant temperatures rise rapidly and can overheat the engine, leading to head gasket or even piston ring failure. This is a great preventative maintenance item when doing any type of timing belt replacement. This is a common replacement around 80,000-100,000 miles.

Over time, rubber hoses and plastic coolant flanges can become brittle due to numerous heat cycles. This often leads to cracks and coolant leaks on the front side of the engine. Additionally, the two o-rings that seal this hose to the cylinder head and the water pump housing can flatten, leading to leaks when reinstalled. When servicing your cooling system, it is advised to replace this hose to prevent leaks and potential overheating.

Modern BMW thermostats are electronically controlled, allowing the DME/ECU to directly regulate coolant flow throughout the engine and its components. This system enables the thermostat to operate based on a broader range of temperature inputs, such as coolant, cylinder head, engine block, and oil temperatures, for more refined control of engine warm-up and temperature across diverse conditions. Unlike traditional thermostats, which simply open or close to permit coolant flow, this system uses a rotary valve for more dynamic control. The rotary valve adjusts to various positions, allowing for partial or full coolant flow to designated passageways as needed. This precision control helps your BMW's engine reach optimal temperatures quickly and ensures efficient heat management under various driving conditions.

This coolant pipe connects to the thermostat module. When replacing the thermostat module, aka the heat management module, or other nearby cooling components, such as the water pump, this coolant pipe should be replaced. The o-ring seal also tends to flatten over time, preventing a proper seal after reinstallation, leading to a coolant leak.

Auxillary water pumps are electric water pumps that pump coolant to critical components of your BMW. A failing pump can cause excessive noise and intermittent cooling issues, leading to potential damage if not replaced quickly enough. If the electric motor dies completely, chances are any parts downstream from the pump will overheat and fail, leading to costly repairs and replacements.

Mechanical water pumps circulate coolant between the engine block, cylinder head, and radiators. Over time, the seals and bearings can wear out, leading to leaks from the impeller shaft and around the pump face. Some BMW water pumps have even had imellers that come loose from the shaft, resulting in little or no coolant flow. Plastic coolant flanges attached to the housing can become brittle over time, cracking or breaking off completely, leading to coolant loss and overheating. Restore cooling functionality and performance with a brand new pump directly from BMW. This coolant pump assembly includes the pump, the coolant support housing, four of the plastic coolant flanges, and a new water pump pulley.

Auxillary water pumps are electric water pumps that pump coolant to critical components of your BMW. A failing pump can cause excessive noise and intermittent cooling issues, leading to potential damage if not replaced quickly enough. If the electric motor dies completely, chances are any parts downstream from the pump will overheat and fail, leading to costly repairs and replacements. Prevent this from happening by installing this brand new Auxillary Water Pump from OEM Bosch!

Over time, rubber hoses and plastic coolant flanges can become brittle due to numerous heat cycles. This often leads to cracks and coolant leaks on the left side of the engine. Additionally, the two o-rings that seal this hose to the water pump flange and the thermostat module housing can flatten, leading to leaks when reinstalled. When servicing your cooling system, it is advised to replace this hose to prevent leaks and potential overheating. This is especially helpful due to its cramped location, requiring the intake manifold to be removed for replacement.
