The 034 Motorsport Coolant Adapter for Block is an improved, CNC machined aluminum cooling adapter for virtually all late Audi I5 20V blocksThis adapter replaces the original plastic cooling adapter (25mm) used in later AAN, ABY, and ADU engines. Over time, these plastic adapters can wear out or even break completely from the heat of the engine compartment, leading to coolant leaks and other problems. Our high-quality, billet aluminum cooling adapter provides a durable and reliable solution. This adapter routes coolant from the back of the engine block to the heating system and is designed to last a lifetime. The adapter includes a new bolt and O-ring seal for easy installation.
For proper fitment, we recommend applying a light coat of RTV (silicone sealant) to the o-ring before installing the adapter. This will help seal any imperfections or damage to the engine block surface. Ensure all rust and residue from the old o-ring and housing is removed from the engine block; otherwise, the new unit will not fit properly. This part has been tested and validated on a properly maintained, rust-free engine block. If you experience any installation issues, thoroughly clean the opening in the engine block until the new adapter fits properly. The fit of this part is identical to that of a new OEM unit, ensuring an easy and reliable installation. With this upgraded cooling adapter, you can extend the life of your engine and minimize the risk of coolant leaks, which is crucial for the performance and reliability of your Audi I5 20V engine. An essential upgrade for anyone looking to improve or maintain their vehicle.
