SneedSpeed R56 Aluminum Thermostat Housing Assembly – Complete with Thermostat, Gasket & Sensors

Upgrade your MINI Cooper's cooling system with a durable aluminum thermostat housing designed to replace the factory plastic housing.

The SneedSpeed R56 Aluminum Thermostat Housing Assembly provides a durable replacement for the original plastic thermostat housing found on R56-generation MINI Cooper engines.

Factory plastic thermostat housings are known to deteriorate over time due to repeated heat cycles, resulting in coolant leaks, cracks, and cooling system failures. This upgraded aluminum housing eliminates the plastic housing's susceptibility to cracking while providing a strong, long-lasting solution.

Supplied as a complete assembly with the thermostat, gasket, and sensors included, this kit makes replacing your original housing straightforward.

Why Upgrade to Aluminum?

The original plastic thermostat housing is a common source of coolant leaks as MINI engines age. Repeated exposure to engine heat and cooling system pressure can cause the plastic to become brittle, warp, or crack.

An aluminum housing provides a more robust alternative, reducing the risk of housing-related failures while maintaining the factory cooling system's intended operation.
