Audi 5 Cylinder Block Stainless Coolant Stub
Our Audi 5 cylinder block coolant stub replaces the corrosion prone factory steel part with a machined stainless steel part.
The factory part is a light press-fit into the block. It is removed by drifting out from the water-pump cavity. Our repalcement part then taps in.
Installation is even easier if the new coolant stub is cooled to -20c in the freezer immediatelty prior to install.
