Installation Notes

Verify the thread size is M10x1 and confirm the pressure specification before installation. Tighten to 20 Nm and use the correct 24 mm wrench size for service access. Check the connector style and wiring terminal orientation before reconnecting the harness. Confirm vehicle-specific fitment by model year and engine application, especially on Volkswagen Beetle, Jetta, and Passat listings with pressure-note variations.
