Rein CTA0040 Engine Coolant Thermostat Housing Assembly
OE Thermostat Housing Assembly
Rein CTA0040 is an OE quality engine coolant thermostat housing assembly built for direct replacement service on select BMW diesel applications. It is engineered to match original equipment design specifications, with a thermostat calibrated to 88 degrees Celsius for stable engine operating temperature.
Compatible with 2009-2013 BMW X5 and 2009-2011 BMW 335d, this Rein thermostat assembly is made to the material and tolerance requirements of the factory part for straightforward installation and consistent cooling system performance.
- Matches original equipment design specifications
- Direct fitment for easier installation
- Built to strict engineering standards for materials and tolerances
- Thermostat calibrated to 88 degrees Celsius
- OE quality replacement for BMW cooling system service
Product Details
The Rein CTA0040 thermostat housing assembly is manufactured as an application-specific replacement for vehicles that require OE-style fit and function. Rein uses vehicle-specific construction in metal or plastic, depending on factory requirements, and forms housings from molds cast directly from OEM parts to help maintain factory dimensions. The result is a thermostat assembly designed for accurate fitment on BMW X5 and BMW 335d cooling systems.
This part cross-references URO 11517805811 for the same application.
Common Cooling System Issues
- Engine running too cool or too warm
- Temperature fluctuations during normal driving
- Thermostat housing replacement due to wear or cracking
- Cooling system service on BMW X5 diesel models
- Cooling system service on BMW 335d diesel models
Installation Notes
Install as a direct replacement thermostat housing assembly for the listed BMW applications. Verify the cooling system is properly drained, inspect mating surfaces and seals, and follow the vehicle service procedure for refill and bleeding after installation. Installation hardware is not included.
Quality Assurance
Rein OE quality thermostat assemblies are built to meet or exceed OE material requirements and are temperature calibrated for consistent response. The housing design and manufacturing tolerances are based on OEM part geometry to support proper fit and service life in BMW cooling system applications.
