Coolant pipe
1. Check the Schäfer coupling for wear and damage:
– Clean the Schäfer coupling thoroughly and check it for wear and damage.
– Check the pipe for clogging; clean or replace it if necessary.
– Check the groove and the circlip (3) of the Schäfer coupling for wear and damage and replace them if necessary.
– Check the Teflon ring spacer (2) for damage and deformation and replace it if necessary.
– Always replace the O-rings (1 and 4).
– Avoid damage to the Teflon ring spacer (2).
– If the Schäfer coupling is leaking and/or is worn as shown (1 and 3), the actuator must be checked.
Actuator
2. Check the actuator connection for wear and damage:
– Clean the actuator connection thoroughly and check it for wear and damage.
If the actuator connection is worn, the complete assembly must be replaced.
– Check the circlips (5) and groove of the actuator connection for wear and damage.
The groove of the actuator must be clean and undamaged. If the groove of the actuator is damaged, the complete assembly must be replaced.
– If re-using the actuator and the Schäfer connection is leaking and/or the circlip is worn as shown, always replace the circlip (5).
Make sure that the circlips (5) are present and correctly fitted.
3. Before installing the pipe, lubricate the Schäfer coupling with the specified mounting product.
4. Check after installing that the coolant pipe is properly locked in the actuator housing.
