The 06E 117 021G Oil Cooler by Mahle is a direct-fit OEM-quality replacement designed to restore proper engine oil temperature regulation on select Audi V6 applications. Specifically, this oil cooler transfers excess heat from the engine oil into the coolant circuit, preventing oil from thinning under sustained high-load conditions. Furthermore, the Mahle 06E 117 021G Oil Cooler is manufactured to OEM dimensions, ensuring direct fitment with factory coolant connections and mounting hardware — no modifications required.
Oil cooler failures typically develop gradually, so recognizing the early warning signs helps prevent costly secondary engine damage. First, milky or foamy oil on the dipstick or inside the oil filler cap strongly indicates coolant is mixing with engine oil through a failed cooler. Additionally, coolant loss without a visible external leak is another reliable sign that the cooler is seeping internally. Furthermore, an overheating engine under sustained load — despite a functional cooling system — can point to a restricted or damaged oil cooler. In more advanced cases, sludge buildup resulting from contaminated oil can cause premature bearing wear throughout the engine.

Always replace the oil cooler gasket and sealing O-rings at the time of installation — reusing old seals is a leading cause of post-repair leaks. After installation, refill both engine oil and coolant to the correct levels using manufacturer-approved fluids. Next, run the engine to full operating temperature and inspect all connections carefully for any signs of seepage. Furthermore, monitor oil and coolant levels over the first few driving cycles to confirm the repair is sealed completely. Finally, if coolant contamination was present, flush the engine oil system thoroughly before refilling with fresh oil.
Always verify fitment by VIN before ordering.

The Meyle 8E0 121 403 Coolant Tank is a direct-fit OEM-style expansion tank engineered for Audi A4 B6 and B7 platform models. Furthermore, it manages thermal expansion, maintains correct system pressure, and serves as the primary coolant fill point — with an integrated level sensor included for a complete, plug-and-play installation.
The 06K 121 143 is an OE-spec coolant hose adapter for select Volkswagen and Audi EA888 1.8T and 2.0T applications. Precision-molded to factory specifications, this direct-fit replacement restores a factory-tight seal at critical coolant junctions — no modifications required. Includes O-ring.
The 022 145 276F is an INA (Schaeffler) OE-quality accessory belt tensioner pulley for select Volkswagen and Audi 3.2L and 3.6L VR6 applications. Built to factory profile with a precision sealed bearing, this direct-fit pulley restores correct belt tracking and quiet operation across the accessory drive — no modifications required.
The 8W0 122 293A is a Genuine Audi OE upper coolant hose coupling for the Audi A4 (B9), A4 allroad, A5, and A5 Sportback equipped with the 2.0L 45 TFSI petrol engine (2017–2020). Positioned at the water pump housing, this flange connects the upper radiator coolant hose and includes a C-clip and seal in the box. Because this coupling is a single-use component, always install a new unit whenever the upper coolant hose is disturbed — no modifications required.
The 5N0 122 291C is an OE-style lower radiator coolant hose adapter by VIKA, engineered for the VW Tiguan Mk1 (5N-chassis) with the 2.0L four-cylinder engine. Positioned at the front lower radiator hose junction, this coupling piece connects the lower coolant hose to the radiator outlet port, completing the primary cooling circuit return path. It serves as a cost-effective alternative to the Genuine VW lower adapter. Always confirm fitment by VIN before ordering.
