Detailed description

This engine coolant thermostat housing is designed for 2002-2008 Mini Cooper cooling system service where the original plastic housing has become brittle, warped, or cracked. The aluminum construction helps maintain flange integrity under heat cycling, while the OE-style dimensions support proper sealing and hose alignment. The housing is intended for direct replacement use on Mini Cooper applications listed for part number 11537512733PRM.

URO Premium products are re-engineered to address known failure points in original components, and this thermostat housing follows that approach with a more robust material choice and factory-style fit. If you are replacing a leaking thermostat housing on a Mini Cooper, this part provides a metal upgrade without changing the original cooling system layout.

This part cross-references BMW/Mini OE number 11 53 7 512 734 and URO-007950 for the same application.

What it helps solve

• Coolant leakage from a cracked plastic thermostat housing
• Warped flange surfaces that can compromise sealing
• Broken or brittle housing necks from heat and age
• Improper hose connection fit caused by distorted OE plastic
• Repeat thermostat housing replacement on Mini Cooper cooling systems

Installation notes and tips

Verify the housing shape, outlet port layout, and sensor-port configuration against the original part before installation. This thermostat housing is manufactured to OE dimensions for bolt-on replacement, but the thermostat is not included and the gasket or seal is not included. Inspect mating surfaces, hoses, and adjacent cooling components during service to help prevent repeat leaks.

For best results, flush and refill the cooling system with the correct coolant after installation and bleed air from the system according to factory procedure. This helps maintain stable operating temperature and supports proper thermostat housing performance on Mini Cooper models.

Quality assurance

URO Premium Heavy Duty Aluminum Upgrade parts are backed by a Limited Lifetime / Unlimited Mileage Warranty. The 11537512733PRM thermostat housing is built to OE dimensions and uses upgraded aluminum construction to improve durability over the original plastic design.
