Febi Expansion Tank Cap

The Febi Expansion Tank Cap (also called a coolant reservoir cap, coolant tank cap, or radiator expansion tank cover) seals the engine cooling system's expansion tank. It helps the system hold the correct operating pressure. Febi is a well-known supplier of aftermarket parts for European and import vehicles, and Febi's parts are made to meet or exceed OE requirements.

Key Features:

• Seals the coolant expansion tank to keep pressure stable in the cooling system
• Has a pressure relief function that vents excess pressure and helps protect hoses, the radiator and the tank
• Helps reduce coolant loss and supports reliable engine temperature control
• Made to OE-equivalent standards for a dependable seal and fit
• Straightforward replacement. Fit it after the engine has cooled completely

A worn or damaged cap can cause coolant loss, pressure problems and overheating. Replacing it is an inexpensive way to keep the cooling system in good working order. Select the variant with the part number that matches your application.
