Product Details

This Four Seasons 86091 housing is intended for lower coolant outlet service on the Volkswagen Lupo and is built around the housing assembly itself rather than a complete thermostat service package. The plastic design follows the original equipment style for the application, making it a direct-fit replacement choice when the outlet housing is cracked, warped, or leaking. This part cross-references Motorad TA9958 for the same application.

Common Problems This Part Can Address

• Coolant leakage at the lower outlet housing
• Cracked or brittle plastic housing
• Warped sealing surface at the coolant outlet
• Failed housing replacement during cooling system repair
• Service needs where the thermostat is reused separately

Installation Notes

Verify the vehicle year and lower housing configuration before installation. Because the thermostat and gasket or seals are not included, transfer or source the required related components separately as needed for the repair. Inspect the mating surfaces, coolant passages, and adjacent hoses before reassembly on the Volkswagen Lupo cooling system.
