4.2. Connection of hoses of system of cooling

The prevention

Hoses can be removed only after cooling of the engine to avoid ошпаривания. Before the beginning of works merge cooling liquid from cooling system.


Usual connection of a hose represents a hose of system of the cooling, pulled against the stop on the union and fixed from above a collar. For hose removal it is necessary to weaken a collar, to shift it from a junction on a hose and to pull together a hose from the union. If the hose densely sits on the union at hose tightening turn it every which way or hook the end of a hose a screw-driver edge.

The prevention

At removal of a hose from the radiator union be careful, since the radiator union fragile and it can be broken easily.

In a case if the hose does not act in film from the union, it is possible to cut off it on the union and, having cut along an axis, to remove from the union. In this case it is necessary to replace a hose with the new.



The prevention

At any connection of a hose with a special connector it is necessary to establish a new sealing ring always.

1. On some models for hose connection special plastic connectors can be established. To remove this type of a connector, it is necessary to operate as follows.
2. For removal of a hose from a special connector turn a ring of blocking (2) against the stop in an eye (1).
3. Wring out an eye of a connector of a hose for clearing of captures (3).
4. Take away a hose and a special connector from a radiator.
5. At connector installation wipe both half of connector a pure fabric.
6. Replace ring consolidation with a connector. The installation site of a new sealing ring is specified by an arrow.
7. Turn a blocking ring clockwise before click.
8. At installation of a connector of a hose into place correctly arrange a focusing groove (it is specified by an arrow).
9. Establish a connector on a radiator to защелкивания captures.
10. Check up reliability of connection, having pulled for a hose.
11. Add a liquid in cooling system.
12. Check up cooling system on tightness.



The prevention

At any hose connection защелкиванием it is necessary to establish a new sealing ring always.

1. On some models hoses of system of cooling with latched connectors are established, i.e. connecting муфта is fixed by a lock ring (the sealing ring of a connector is specified by an arrow).
2. To separate this type of connection, using a small screw-driver, remove a lock ring. After that it is possible to take out a hose from a connector.
3. At connector assemblage establish new ring consolidation on an internal part of a connector and connect both parts of a connector before fixing by their lock ring. Check up, that the lock ring was correctly established in a groove of an internal part of a connector. Moving a hose to the parties, check up reliability of connection and fill up cooling system.
