| 1. The thermal vacuum valve is located on the right side of the inlet collector. The engine and an inlet collector have to be cold at removal of the valve. |
| 2. Merge a part of cooling liquid from the cooling system (see subsection 2.4.5) in order that its level fell slightly below than the valve, or prepare a suitable cap to stop up an opening in an inlet collector after removal of the valve. If you decided to use a cap, try not to damage a collector and do not use anything of that kind that will allow foreign objects or substances to get to the cooling system. |
| 3. Disconnect both hoses from the valve. |
| 4. Accurately unscrew the valve from an inlet collector and remove a sealing ring (if it is established). |
| 5. Installation is carried out upside-down removals. At installation use a new sealing ring (if it is necessary). If the sealing ring was not established on the valve, grease its carving with sealant before installation. |
