BMW Cooling System Parts & Accessories for BMW 5 Series G30 (2017+)

Clear BMW chassis

Please ensure your correct model is selected

The cooling system is arguably the weakest point in numerous BMWs. If you drive an aging BMW or plan on taking your car to the track like we do, we recommend beefing up your cooling system before going to the track. Generally, the main components in your cooling system that are prone to failure include the following: expansion tank, factory hoses, water pump, thermostat, fan (especially if your vehicle comes factory with a clutch fan), and radiator. Factory BMW expansion tanks are plastic and prone to either breaking off at connection points or combusting. As factory rubber hoses age they either crack or break over time - we offer silicone cooling hose upgrades for most applications to avoid future failures. If you have an older vehicle, your water pump likely comes from the factory with a plastic impeller - we offer upgraded water pumps with metal impellers that are far more reliable. Newer model BMWs utilize electric water pumps - BMW spent millions of dollars engineering these water pumps, but they fail so often that we recommend replacing at 60,000 mile service intervals to avoid being stranded on the side of the road. In terms of thermostats, we offer various upgraded thermostats for racing applications. If your BMW utilizes a clutch fan from the factory, we have several options available in terms of universal electric fans - we recommend replacing these to avoid sending brittle plastic fan blades through your hood. For radiators, we recommend swapping out your radiator for one that does not use plastic connection points like your factory radiator.

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.

Red Line SuperCool Performance Coolant fortified with WaterWetter is a 50/50 prediluted antifreeze/coolant designed to maximize the performance of your cooling system with superior protection against cavitation corrosion/erosion. Using 100% SuperCool Performance protects the entire cooling system, keeping new components like new for 5 years/150,000 miles and prevents further damage to older components. Red Line’s proprietary coolant additive formula enhances the fluid’s ability to transfer heat, reducing operating temperatures by up to 20*F and prolonging the life of the entire cooling system. Red Line's SuperCool is an OAT coolant that is a Nitrate and Silicate Free product with its own proprietary corrosion technology to offer superior protection for aluminum engines found in all European vehicles, performance vehicles, as well as other applications. SuperCool will not void the factory warranty either. It can be used to top off the existing coolant of any BMW and will not cause any ill-effects on the cooling system because it is silicate and nitrate free. It is still better to flush it out and switch completely to SuperCool to get all the full benefits of the product in performance and protection.

Furthermore, they've upgraded the factory plastic flanges to 6061-T6 billet aluminum with black anodizing, enhancing corrosion resistance.

This upgraded hose is the ultimate solution, providing protection against dislodged charge pipes and the heat generated from spirited driving or track use.

Key Features:

Direct factory replacement for easy installation 6061-T6 billet aluminum with black anodizing for improved corrosion resistance Durable 7-ply silicone available in three colors Upgrade your BMW B58TU engine with this enhanced cooling hose from Vargas Turbo Technologies for superior performance and reliability.

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.

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.

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.

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.

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.
