Febi Thermostat Housing

The Febi thermostat housing (also called a coolant flange, thermostat cover or water outlet housing) holds the engine thermostat in place. It also gives the cooling system a sealed connection point for coolant hoses. It helps the engine reach operating temperature quickly and keeps it there. This supports consistent performance, fuel efficiency and engine protection.

Key Features:

• Made as a replacement part for the original thermostat housing
• Built to hold up to constant heat cycling and exposure to coolant
• Gives a leak-resistant seal at the thermostat and coolant connections when installed with the correct gaskets or seals
• Produced by Febi, a brand of Bilstein group, which supplies parts to the independent aftermarket
• Quality-checked to meet OE-level fit and function

A cracked or leaking housing can cause coolant loss, overheating and engine damage. Replacing it with a Febi thermostat housing helps restore proper cooling system operation. Replace the thermostat, gaskets and seals at the same time, and refill the system with the coolant the vehicle manufacturer specifies.
