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

Includes housing and sealing o-ring A thermostat that opens sooner promotes better cooling in your vehicle. Running a lower temperature thermostat will keep everything much cooler. Keeping the engine cooler will help reduce and improve the life of the seals in your engine, saving you time and money, while also helping to increase engine performance. A tune might be required to gain the most from this modification, as well as to get your car's ECU accustomed to seeing lower temperatures.

Water Pump And Thermostat Kit - BMW N55 F Chassis

Ensure optimal engine cooling and performance with this high-quality Water Pump And Thermostat Kit - BMW N55 F Chassis. In the mid-2000s, BMW introduced electronically controlled water pumps and thermostats for better temperature regulation and efficiency. However, these components tend to have a shorter lifespan compared to traditional mechanical designs, often failing before BMW’s recommended 80,000-mile service interval.

This complete kit from Turner Motorsport includes premium-quality components that match OEM specifications, providing reliable and efficient cooling system performance. Maintaining a properly functioning cooling system helps prevent overheating, enhances efficiency, and extends engine life.

Signs Your Water Pump and Thermostat May Need Replacement:

  • Engine overheating or failing to reach operating temperature
  • Water pump running intermittently or erratically
  • Cooling fans operating at maximum output
  • Engine fault codes, including 20A804

Upgrade your BMW N55 F Chassis cooling system with this all-in-one kit for worry-free performance and longevity.
