Removal, check of serviceability and thermostat installation

At installation the new sealing ring of the thermostat is required.


1. Disconnect a cable of weight from the battery (on models Scenic address to the Head an engine Electric equipment).
2. Merge a liquid from cooling system. The thermostat is established in a casing, on the left end of a head of the block of cylinders.
3. Where it is necessary, remove assemblage of the air filter (the Head of the Power supply system and release), then let out adjoining electroconducting and hoses from fixing скоб and displace them from a thermostat casing to facilitate access.
4. Disconnect hoses of system of cooling from a cover of a casing of the thermostat (address to Section Separation and replacement of hoses of system of cooling).

5a. Turn away nuts/bolts.

5b. Accurately take a thermostat casing/cover (address to illustrations). Where is available, remove a casing lining - it is subject to replacement.

6. Take the thermostat from a casing and remove a sealing ring (address to an accompanying illustration).


1. Suspend the thermostat on a wire piece in the container with cold water and ship in the container the thermometer. Be convinced that the thermostat does not concern container walls. Finish water to boiling - the thermostat should open. If it not so, replace it.
2. Compare temperature of opening of the thermostat to the data resulted in Specifications. The working temperature is specified also on the thermostat.
3. The thermostat which is not closed after water has cooled down, also should be replaced.


1. Make installation in return sequence, paying attention to the following:
a) Establish a new sealing ring and be convinced that the thermostat is focused correctly (a spring in a casing). The casing lining (where is available) also should be replaced.
b) In summary, fill cooling system.
