4.2. Connection of hoses of the cooling system


Prevention

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


USUAL CONNECTIONS OF HOSES

PERFORMANCE ORDER
Usual connection of a hose represents the cooling system hose pulled against the stop over the union and fixed from above by a collar. For removal of a hose 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, then when tightening a hose turn it in different directions or hook the end of a hose a screw-driver edge.

Prevention

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

In case the hose is not removed 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 the hose needs to be replaced with new.



HOSES WITH THE SPECIAL CONNECTOR

PERFORMANCE ORDER

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 connection of a hose special plastic connectors can be established. To remove this type of a connector, it is necessary to work as follows.
2. For removal of a hose with a special connector turn a ring of blocking (2) against the stop in an eye (1).
3. Wring out a hose connector eye for release of captures (3).
4. Take away a hose and a special connector from a radiator.
5. At installation of a connector wipe both half of a connector with 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 the focusing groove (it is specified by an arrow).
9. Establish a connector on a radiator to a zashchelkivaniye of captures.
10. Check reliability of connection, having pulled for a hose.
11. Add liquid in the cooling system.
12. Check the cooling system for tightness.

CONNECTION OF THE HOSE BY ZASHCHELKIVANY

PERFORMANCE ORDER

Prevention

At any a zashchelkivaniye it is always necessary to establish by connection of a hose a new sealing ring.


1. On some models hoses cooling systems with the latched connectors are installed, i.e. the connecting coupling 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 the small screw-driver, remove a lock ring. After that it is possible to take out a hose from a connector.
3. At assembly of a connector 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 that the lock ring correctly was established in a groove of an internal part of a connector. Moving a hose to the parties, check reliability of connection and fill up the cooling system.
