BMW Cooling System Parts & Accessories for BMW X Series F26 (2015+)

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.

Some of the biggest issues when owning a BMW can come from cooling system components. Even through years of improvement, the same failure is seen with the plastic fittings and adapters from years of hot to cold temperature fluctuation. The N52/N54/N55/N20 engine sees failure at the plastic cylinder head outlet adapter connecting the cylinder head to the thermostat hose. The stock plastic adapter simply shears off at the end of the barbed fitting, creating a massive coolant leak. The engineering team at ECS Tuning decided a billet aluminum piece was a much better option to contend with the temperature fluctuation. Since other offerings on the market want you to modify your OE hose to be reused, they even developed a silicone replacement hose. These 2 pieces can be purchased separately if you decide to reuse your existing OE hose or in a package kit together for a single click upgrade. Features: Manufactured from billet 6061-T6 with type III anodized for exceptional durability and corrosion resistance. Much stronger part than OEM plastic ​​Will not become brittle and fatigued over time due to thermal cycling. This will prevent the part from breaking during removal and re-installation. Follows OEM form for perfect fitment. Utilizes (and includes) OEM O-ring 11537545278 to ensure a proper seal. Recommended clamp size is 25-40mm

A failing water pump can show early warning signs like coolant leaks or a whining noise from the engine bay—but with electric water pumps, failure can be sudden, often with no warning beyond rapid overheating.

If you suspect your water pump is on its way out, prompt replacement is critical to avoid engine damage. Stay alert to any changes in cooling system performance.

Note: Aluminum mounting bolts are single-use and must be replaced during installation.

This is the mounting bolt used for the water pump on all N55 engines as well as later (updated) N54 engines. These are sold per bolt and 3 are required for mounting the water pump.

This is a new and revised bolt design to match the updated water pump ( p/n 11517632426 ). BMW changed the design for the N55 and all subsequent replacement N54 pumps. The updated pump does not use a rubber isolator in the mounting flange. The previous water pump did have this rubber mount and required a longer bolt. The new bolts are also zinc-coated grade 8.8 steel instead of aluminum. That means the new bolts are re-usable instead of 1-time use like the old design.

Sold per bolt. 3 are usually required for the N54/N55 water pump.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.
