- Pull the cover up while turning it counterclockwise. The original parts have an arrow indicating the direction of unscrewing.
- If the cap breaks during removal, use pliers to carefully remove the remaining threaded part.

- 🧴Before installation, apply to the O-ring silicone grease - this will prevent sticking.
- 🌡️ Make sure that the temperature of the lid and the tank is the same (for example, both are warmed up to room temperature), otherwise the plastic may burst when tightened.
If the cover leaks after installation, check:
- The integrity of the o-ring (sometimes it remains on the old cover).
- Evenness of fit - perhaps dirt on the neck of the tank is interfering.
- Condition of the threads on the tank - if they are stripped, the tank will need to be replaced or repaired using a thread insert (helicoil).
Use a torque wrench with a torque of no more than 1.5 Nm when tightening - this will prevent damage to the plastic.
