Product Description

The Moca CAP EXPANSION TANK 1.2 BAR is an essential cooling pressure cap designed for select Audi and Volkswagen vehicles. This cap maintains the correct pressure within the expansion tank, helping to regulate coolant flow and prevent overheating. Its robust plastic construction and practical grip tabs make it easy to fit and remove during routine maintenance.

This cap is suitable for various Audi and Volkswagen models. However, fitment can vary between models and years, so it is important to confirm your vehicle's model, year, engine size, and engine code before purchase to ensure compatibility.

A faulty or worn expansion tank cap can cause several issues, such as coolant leaks, low coolant warning lights, engine overheating, or excessive pressure in the cooling system. If you notice any of these symptoms, the cap may need replacement.

When replacing your expansion tank cap, ensure the engine is cool before removing the old cap to avoid injury from hot coolant or steam. Always inspect the sealing surfaces and replace the cap if there are any signs of cracking, warping, or loss of pressure.

Order your cooling pressure cap from MiMi Auto Parts for reliable service and nationwide delivery in South Africa. Our specialists are available to help you select the correct part for your vehicle, giving you peace of mind for your next repair.
