Thermostat Housing- 06K 121 111P(Genuine)

Description

Product Description

The 06K121111P Thermostat Housing / Coolant Outlet is an OE‑spec cooling system component used on many Volkswagen and Audi 1.8T & 2.0T EA888 engines. This molded housing connects the thermostat area to the upper radiator and heater hoses, providing a sealed path for coolant flow out of the engine.

Factory plastic housings are constantly exposed to heat and pressure and can warp, crack, or leak over time. Symptoms often include coolant smell, pink residue near the housing, slow coolant loss, or overheating. Replacing the housing with this 06K121111P OEM‑style unit restores leak‑free operation and reliable coolant routing.

• Direct bolt‑on replacement with factory hose connections
