Cap Expansion Tank 1.1/1.2Bar (Skp) (2.1 2.3 2.5 2.6) (Volkswagen Microbus T3) is designed to regulate the pressure inside the cooling system of your Volkswagen Microbus T3. This part ensures that the coolant expansion tank maintains the correct pressure between 1.1 and 1.2 bar, preventing overheating or coolant loss during engine operation.
The expansion tank cap is a critical component that fits specific engine variants (2.1, 2.3, 2.5, 2.6 litres) commonly found in the Volkswagen Microbus T3 model range. When installed on the expansion tank, it seals the system while allowing excess pressure to release safely. Checking your existing cap for matching pressure rating and compatibility with these engine sizes is essential to ensure correct system performance.
This listing covers the cap alone, identifiable by the SKU BB-251053, categorized under fuel tank components for Volkswagen vehicles. Buyers should compare the old cap’s pressure rating and physical design to confirm suitability. This part is particularly useful if the current cap shows signs of wear or if you experience coolant overflow or engine temperature inconsistencies.
