Water Pump & Thermostat – 06H 121 026BF (Borsehung)

Description

Product Description

The 06H121026BF Thermostat & Water Pump Assembly is an OE‑spec integrated cooling module for many Volkswagen and Audi 2.0T TSI/TFSI EA888 engines. This unit combines the mechanical water pump and electronically‑controlled thermostat in a single housing, providing fast warm‑up, stable operating temperature, and reliable coolant circulation.

Aging original units are known to develop coolant leaks at the housing seam, cracked plastic, and thermostat performance faults, which can lead to overheating and warning lights. Replacing the complete assembly with 06H121026BF restores cooling system integrity and protects your turbocharged engine.
