VW Audi EA888 Gen 3 & 4 2.0T Upgraded Aluminium Thermostat & Water Pump Assembly

RRP EA888.3/4 ALUMINIUM

Thermostat Housing & Water Pump Upgrade

06L12111

Product Description

Designed and produced by Road Rage Performance this unit will solve the notorious coolant leak issue on your 2.0 TSI / TFSI engine once and for all. The factory-fitted thermostat housing and water pump structure on the EA888 Gen 3 and Gen 4 engines is notorious for failing. Constructed from factory plastic, the stock housing warps, cracks, and degrades rapidly under repetitive engine heat cycles, leading to premature coolant loss, water pump failure, or catastrophic overheating.

This premium upgrade kit features a heavy-duty, robust Cast Aluminium Housing Replacement designed to withstand severe thermal expansion and continuous high-temperature pressure. Engineered to exact OEM specifications, it permanently resolves structural warping while acting as a direct bolt-on upgrade package. Don't risk replacing a leaking plastic unit with another plastic unit that will inevitably fail again—upgrade to a permanent aluminium fix.

Cast Aluminium Construction

Completely eliminates plastic warping, hairline cracks, and structural heat fatigue across high-load operations.

Full Drop-In Assembly

Designed as a comprehensive drop-in solution featuring premium seals to guarantee an airtight, leak-free configuration.

Peace Of Mind Tuning

Highly recommended for stock daily drivers and absolutely essential for Stage 1, 2, or Stage 3 high-boost builds.
