Genuine BMW Engine Coolant Thermostat Housing

The Genuine BMW Engine Coolant Thermostat Housing (also called a thermostat cover or coolant thermostat housing) is an original equipment component of the engine cooling system. It holds the thermostat and gives the coolant a sealed passage. This helps the engine reach operating temperature and stay there.

Key Features:

• Original BMW part, built to the manufacturer's engineering and quality standards
• Holds the thermostat in the coolant circuit and helps regulate engine temperature
• Gives a sealed connection for coolant passages and hoses
• Made to handle the heat cycles, pressure and coolant exposure of the cooling system
• Replaces the original housing, which can crack, warp or leak with age and heat

A worn or leaking thermostat housing can cause coolant loss, overheating or poor temperature control. Replacing it with a Genuine BMW part restores a proper seal and dependable cooling system performance. Choose the item that matches your needs from the available options on this page.
