6.4.2.3.2. The thermovacuum valve

The thermovacuum valve on models with the carburettor engine

The thermovacuum valve (it is specified by an arrow) is located on the right party of an inlet collector.

Replacement

PERFORMANCE ORDER
1. The thermovacuum valve is located on the right party inlet a collector. The engine and an inlet collector should be cold at valve removal.
2. Merge a part of a cooling liquid from cooling system (see subsection 2.4.5) that its level has fallen hardly below the valve, or prepare approaching заглушку to stop up an aperture in an inlet collector after valve removal. If you have decided to use заглушку, try not to damage a collector and do not use anything such that will allow extraneous subjects or substances to get in 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 spent upside-down removals. At installation use a new sealing ring (if it is necessary). If the sealing ring has not been established on the valve, grease its carving with hermetic before installation.
