The factory plastic coolant outlet on EA888 engines is a known weak point. As it is fitted directly next to the turbocharger, it is exposed to high temperatures, which eventually cause the plastic to become brittle, crack and lead to coolant loss.
Racingline’s CNC-machined aluminium replacement is designed as a more durable solution. It is a direct replacement for the original part 06K 121 143, replacing the factory plastic housing with an aluminium outlet resistant to warping, softening and heat-related cracking.
Why choose an aluminium outlet?
- Prevents sudden coolant loss caused by the original plastic part cracking next to the turbocharger.
- CNC machining from a solid aluminium billet provides high strength and long-term resistance to heat.
- The anodised surface protects against corrosion caused by coolant additives, oil and road salt.
- Direct installation using the original mounting points and hoses.
- A pre-installed O-ring is included, so the part is ready for installation.
The kit includes
- 1× Racingline aluminium coolant outlet
- 1× pre-installed O-ring
Installation
Installation is straightforward for anyone familiar with basic mechanical work. You will need a Torx T30 screwdriver, hose-clamp pliers and a rubber clamp to temporarily close the coolant hoses during replacement. After installation, top up the coolant and bleed the cooling system.
Compatibility
The product is intended for vehicles with 1.8 TSI and 2.0 TSI EA888 Gen.3 and 2.0 TSI EA888 Gen.4 engines. It fits numerous models from VW, Audi, SEAT, Škoda and Cupra, including the Golf GTI, Golf R, S3, TT, Leon Cupra and Octavia vRS.
