Product Description

The Moca CAP EXPANSION TANK 1.5BAR is a cooling pressure cap designed specifically for select Volkswagen models. This cap plays a vital role in maintaining the correct pressure within your vehicle's cooling system, helping to prevent overheating and coolant loss. Its robust plastic construction and easy-grip design allow for secure fitting and removal when needed.

This cooling pressure cap is suitable for Volkswagen vehicles, including certain Golf, Jetta III, and Polo models from the late 1990s to early 2000s. Always confirm your Volkswagen's model, year, engine size, and engine code to ensure compatibility before placing your order.

A failing expansion tank cap can cause several issues, such as coolant leaks, engine overheating, or fluctuating coolant levels. You might also notice steam from the engine bay or a loss of pressure in the cooling system if the cap is not sealing as it should.

Replace your expansion tank cap if you observe any signs of wear, damage, or pressure loss. It is also advisable to change the cap during routine cooling system maintenance or when replacing the expansion tank itself.
