Metal Water Pump and Thermostat Kit with Belt - VW/Audi / 1.8T & 2.0T / MQB / EVO4

Upgrade one of the most common cooling system failure points on VW and Audi EA888 Gen 3 and Gen 4 1.8T and 2.0T engines with this complete all-metal water pump and thermostat kit.

The factory VW/Audi water pump and thermostat assembly uses a plastic housing that can develop coolant leaks as it ages and goes through repeated heat cycles. This kit replaces the factory plastic assembly with a Road Rage Performance aluminum water pump and thermostat housing for improved strength and long-term durability.

Designed for a wide range of VW and Audi models including the GTI, Golf R, Golf, Jetta GLI, Tiguan, A3, S3, TT, TTS, Q3, Q5, A4, and A5, this kit also includes a new water pump belt and pulley bolt for a more complete replacement.

All-Metal VW & Audi Water Pump Upgrade

Replacing the factory plastic water pump and thermostat housing with an aluminum assembly offers several advantages:

• Full aluminum thermostat and water pump housing

• Eliminates the failure-prone factory plastic housing

• Improved resistance to heat cycling and cracking

• Helps reduce the risk of future coolant leaks

• Direct-fit replacement for compatible VW and Audi applications

• Includes a new water pump belt and pulley bolt

• Ideal for stock, tuned, and performance vehicles

Whether you're replacing a leaking VW or Audi water pump or performing preventative maintenance, this kit provides a more durable alternative to installing another plastic water pump and thermostat housing.
