Caution! Hoses may be removed only after the engine has cooled down to avoid scalding. Before starting work, drain the coolant from the cooling system.
Common hose connections
A typical hose connection is a coolant hose pushed all the way onto the fitting and secured with a clamp on top. To remove the hose, loosen the clamp, slide it off the connection point along the hose, and pull the hose off the fitting. If the hose sits tightly on the fitting, twist it in different directions when pulling the hose off or pry the end of the hose off with a screwdriver blade.
Caution: Be careful when removing the hose from the radiator nipple, as the radiator nipple is fragile and can be easily broken.
Attention! If the hose does not come off the nipple, you can cut it along the nipple and, cutting along the axis, remove it from the nipple. In this case, the hose must be replaced with a new one.
Hoses with special connector
Caution: Whenever connecting a hose to a special connector, a new sealing ring must always be installed.
1. Some models may have special plastic connectors to connect the hose. To remove this type of connector, follow these steps:.
2. To remove the hose with the special connector, turn the locking ring (2) until it stops in the eye (1).
3. Press the eye of the hose connector to release the grips (3).
4. Remove the hose and special connector from the radiator.
5. When installing the connector, wipe both halves of the connector with a clean cloth.
6. Replace the O-ring on the connector. The location of the new O-ring is indicated by the arrow.
7. Turn the locking ring clockwise until it clicks.
8. When installing the hose connector in place, position the alignment groove correctly (indicated by the arrow).
9. Install the connector onto the radiator until the catches snap into place.
10. Check the connection for reliability by pulling on the hose.
11. Add fluid to the cooling system.
12. Check the cooling system for leaks.
Snap-on hose connection
Caution: Always install a new O-ring when making any snap-fitting connection to a hose.
1. Some models are equipped with coolant hoses with snap-on connectors, i.e. the coupling is secured with a retaining ring (the connector sealing ring is indicated by the arrow).
2. To disconnect this type of connection, use a small screwdriver to remove the retaining ring. The hose can then be pulled out of the connector.
3. When assembling the connector, install a new O-ring on the inside of the connector and connect both parts of the connector until they are secured with a retaining ring. Check that the retaining ring is correctly positioned in the groove of the inside of the connector. By moving the hose sideways, check the reliability of the connection and refill the cooling system.
