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.

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.
