Coolant Expansion Tank Cap Tool 1/2in Drive for VAG MQB

A coolant expansion tank cap tool made for removing and refitting coolant reservoir caps on VAG MQB vehicles. It gives the correct fit on the cap, helping you get it loose more safely than using general-purpose grips or improvised tools.

Used for cooling system servicing, coolant checks, flushing and repair work where the expansion tank cap needs to come off without damage. Handy for garage work, workshop servicing and home vehicle maintenance, especially on VW, Audi, SEAT, Skoda and Cupra models where cap access or tightness can make the job awkward. It is also suitable for MQB platform vehicles from 2013 onwards, including electric and hybrid models.

The tool connects to a standard 1/2in drive ratchet or torque wrench, so it fits in with tools already in regular use. Its exact-fit shape is made to grip the cap properly, which helps reduce the chance of cracked caps or damage to the tank during removal and installation. Once the cap is broken free with steady pressure, it can then be spun off by hand. For regular cooling system work, having the right fit close to hand helps avoid switching to makeshift tools when the cap is stubborn.
