The Moca CAP EXPANSION TANK 1.4BAR is a cooling pressure cap designed to regulate the pressure within your vehicle's expansion tank, helping maintain optimal coolant levels and engine temperature. This cap is a crucial component in the cooling system, preventing coolant loss and protecting the engine from overheating due to excessive pressure.
This specific cap is compatible with selected BMW, Opel, and Toyota models, including various BMW 1 to 8 Series and X1 to X7 models, as well as certain MINI and other compatible vehicles. Always confirm your vehicle's model, year, engine size, and engine code before ordering to ensure correct fitment.
A failing expansion tank cap can lead to symptoms such as coolant leaks around the cap, overheating, fluctuating temperature gauges, low coolant warnings, or a collapsed radiator hose. You may also notice steam or a sweet smell from the engine bay, or visible cracks and damage on the cap itself.
Replace the expansion tank pressure cap if you observe any signs of pressure loss, visible damage, or if the cap no longer holds the correct pressure. Regular inspection and timely replacement help prevent engine overheating and costly repairs.

Cooling system work involves draining and refilling coolant and may require specialised tools. Professional installation is recommended to ensure correct coolant mixture, bleeding of air from the system, and leak-free connections.
Common signs may include coolant leaks near the front of the engine, engine overheating, a whining or grinding noise from the water pump area, or coolant loss without visible external leaks. Diagnosis should be confirmed before replacement.
Driving with a coolant leak is not recommended. Loss of coolant can lead to engine overheating and potentially serious engine damage. The vehicle should be inspected and the leak repaired before further driving.
Please check the vehicle compatibility section on this page and confirm your vehicle make, model, year, engine size, and engine code before ordering. If you are unsure, contact MiMi Auto Parts before checkout.
