Product Details

The Motorad Integrated Housing Thermostat line focuses on complete thermostat housing assemblies that match OE specifications and processes. For BMW 535i GT, 535i xDrive, 740Li, ActiveHybrid 5, and other listed models, this 828-207 assembly supports accurate coolant temperature regulation and consistent flow control in demanding engine cooling systems. This part cross-references Dorman OE Solutions 902-5172 and Gates 34789 for the same application.

Common Cooling System Issues It Can Address

• Engine running too cool or too hot due to thermostat wear
• Coolant temperature fluctuation during normal driving
• Air trapped in the cooling system after service
• Housing-related leaks from aging thermostat assemblies
• Delayed thermostat response from degraded wax element performance

Installation Notes

Verify the 207 Deg. F temperature specification and confirm vehicle fitment before installation. This assembly includes the thermostat, housing, and sensor on listed applications, but does not include bolts, mounting hardware, gasket, or seal. Inspect mating surfaces, replace worn coolant components as needed, and follow BMW cooling system bleed procedures to remove trapped air.
