Product Description

The Moca CAP EXPANSION TANK 1.6 BAR is an essential component within your vehicle's cooling system, designed to maintain optimal pressure inside the expansion tank. This cooling pressure cap helps ensure that coolant remains at the correct pressure, preventing overheating and coolant loss during normal operation. With a robust plastic construction and secure threaded fit, it provides reliable sealing for compatible Audi and Volkswagen models.

This cap is suitable for selected Audi and Volkswagen vehicles. It is important to match the cap's pressure rating and fitment with your specific model, year, engine size, and engine code to ensure proper operation. If you are unsure about compatibility, consult your owner’s manual or reach out to MiMi Auto Parts for assistance before purchasing.

A faulty or worn expansion tank cap can lead to a range of cooling system issues. Common symptoms include coolant leaks around the cap, overheating, loss of coolant with no visible leaks, low coolant warning lights, or a collapsed radiator hose. You may also notice steam from the engine bay or inconsistent heater performance, all of which can indicate pressure loss in the cooling system.

Replace the expansion tank cap if you notice any of these symptoms, or when the cap no longer seals tightly or its pressure rating is compromised. Regular inspection during coolant changes is recommended, as a worn cap can fail unexpectedly and lead to more costly repairs.

Shop with confidence at MiMi Auto Parts, where we offer nationwide delivery across South Africa. Always confirm your vehicle’s model, year, engine size, and engine code before ordering to ensure the correct fit for your Audi or Volkswagen. Our knowledgeable team is here to help you keep your cooling system running smoothly.
