| Function | Controls coolant flow to radiator, brings engine up to optimal operating temperature; reduces engine wear, carbon deposits and exhaust emissions, fixes common plastic‑housing cracking and coolant‑leak failures |
The thermostat housing regulates coolant circulation as the engine warms up and connects several key cooling-system passages. Replacing the complete assembly can help correct coolant seepage around the housing, deteriorated seals, unstable operating temperatures, and damage around the hose connections on compatible MINI Cooper 1.6L applications.
OE Number and Connection VerificationBefore ordering, compare the original housing with the replacement part’s electrical connector, mounting points, hose-port direction, and overall shape. OE numbers such as 11537534521, 11537647751, and 11538699290 can be used for cross-reference purposes, but the VIN and original part number should remain the primary fitment references.
If the existing hoses feel brittle, swollen, or cracked during removal, inspect the available radiator hoses before reassembling the cooling system.

This thermostat housing is intended for selected 2007–2013 MINI Cooper and 2011–2013 MINI Cooper Countryman 1.6L applications. Engine configurations and production changes may vary within the same model year, so fitment should be confirmed by matching the original housing and OE number rather than relying only on the vehicle model.

Related replacements for other applications are available in the thermostat housing collection.
Allow the engine to cool completely before draining the coolant and disconnecting the hoses. Clean the mounting surface before installing the new housing, keep the seal properly seated, and tighten the fasteners according to the vehicle service procedure. After refilling the cooling system, bleed trapped air and inspect every connection for leaks.
