EVIL ENERGY Thermostat Housing Assembly for Mini Cooper 1.6L (2007–2016) — OE Fit, Includes Thermostat & Gasket

EVIL ENERGY Thermostat Housing Assembly 11537534521 is a direct-fit replacement kit that controls engine coolant flow for 1.6L Mini Cooper engines from 2007–2016.

This replacement thermostat housing assembly from EVIL ENERGY is engineered to match the fitment and function of several OE numbers (11537534521, 11537647751, 1336Z6, 11538699290) and is compatible with Mini Cooper models including 2007–2013 Cooper, 2011–2013 Countryman and 2015–2016 Paceman with the 1.6L engine. The kit includes the thermostat, rubber gasket, plastic housing and a pair of nitrile gloves so you can install a ready-to-fit component with the required sealing hardware.

How does this thermostat housing assembly affect engine temperature control?

The thermostat opens at approximately 221°F (105°C) to manage coolant flow through the radiator and maintain the engine within its designed operating window. Proper regulation helps the engine reach and hold intended temperatures more quickly and prevents prolonged cold running or overheating cycles.

• Opening temperature: 221°F / 105°C for consistent thermal response.
• Includes a precision thermostat element matched to OEM specifications.
• Plastic housing designed to accept the included rubber gasket for an improved seal.
• Helps regulate coolant volume routed to the radiator under different loads.

Will this part fit my Mini Cooper model and engine?

This EVIL ENERGY unit is designed specifically for 1.6L Mini Cooper engines and lists the OE cross-reference numbers so you can verify compatibility. It is intended for the 2007–2013 Mini Cooper, 2011–2013 Mini Countryman and 2015–2016 Mini Paceman models equipped with the 1.6L engine.

• Checks against OE numbers: 11537534521, 11537647751, 1336Z6, 11538699290.

What comes in the kit and what else will I need for installation?

The package ships with the core components required for a standard thermostat housing replacement so you can complete the repair without sourcing additional seals. You may still need basic hand tools, coolant for refill, and some shop supplies to finish the job.

• Included: Thermostat x1, Rubber Gasket x1, Plastic Housing x1, Nitrile Gloves x1.
• Recommended extra items: proper coolant, torque wrench, and replacement clamps if worn.
• Installation note: follow vehicle service manual torque specs and bleed the cooling system after installation.

How does replacing the thermostat housing help vehicle performance and longevity?

Replacing a worn or leaking thermostat housing restores proper coolant routing and sealing, reducing the risk of coolant loss and erratic engine temperatures. While not a cure-all, a reliable housing supports stable engine thermal management, which contributes to consistent performance and reduced wear related to temperature extremes.

• Restores correct coolant flow timing, supporting efficient engine warm-up.
• Eliminates leaks from degraded housings or failed gaskets.
• Helps prevent temperature-related engine stress when combined with proper maintenance.

Who is this for: This EVIL ENERGY thermostat housing assembly is aimed at DIY mechanics and independent shops working on Mini Cooper 1.6L engines who need a cost-effective, OE-referenced replacement. It's a practical option for owners addressing leaks, failed thermostats, or routine cooling-system maintenance who want a ready-to-install kit that includes the matching gasket and gloves.
