Setup, Compatibility & Care
Installation requires basic mechanical knowledge and access to the vehicle's cooling system.
- Preparation: Ensure the engine is completely cold before starting to avoid burns from pressurized coolant.
- Drainage: Partially drain the radiator to lower the coolant level below the sensor port.
- Removal: Carefully disconnect the blade terminal connector and unscrew the old switch using an appropriate socket.
- Installation: Thread the new Hella switch into place, ensuring the sealing washer is seated correctly to prevent leaks. Tighten to manufacturer torque specifications.
- Refill: Top off the cooling system with the manufacturer-recommended coolant, bleed any air from the system, and check for leaks.
Always verify that your vehicle requires an M 22 x 1,5 thread pitch before proceeding, as incorrect force during installation can damage the radiator housing.
