Product Description

This Moca CAP EXPANSION TANK 2.0BAR is a crucial cooling pressure cap designed specifically for BMW vehicles. It helps maintain the correct pressure in your cooling system, ensuring efficient engine temperature regulation and preventing coolant loss. The cap features a 2.0 bar pressure rating, a ribbed grip for easy handling, and clear warning symbols for added safety during maintenance.

This cap is compatible with a range of BMW models, including popular series such as E90, F30, E60, F10, F11, E70, E63, F80, E71, and others. Always check your vehicle’s model, year, engine size, and engine code to confirm fitment before purchasing.

Common symptoms of a faulty or worn expansion tank cap include coolant leaks around the cap, overheating, fluctuating temperature gauge readings, loss of coolant with no visible leaks, excessive pressure in the cooling system, and visible cracks or damage to the cap. You may also notice steam escaping from the cap or a persistent low coolant warning light.

Replace your expansion tank cap if you notice any of these symptoms or if the cap’s seal appears damaged or brittle. A compromised cap can lead to cooling system failure, risking serious engine damage.
