Крыльчатка the fan of system of cooling with гидромуфтой
Fastening nut гидромуфты the fan of system of cooling
|
|
The nut has the left carving. |
The electrofan has 2 speeds of rotation and accordingly joins from 2 thermoswitches which are screwed in a radiator and work at different temperatures. On a part of cars 1 double thermoswitch can be established.
The prevention At performance of works have in view of that is possible сампроизвольное inclusion of the auxiliary fan at thermoswitch operation, even at the switched off ignition.
Check
| PERFORMANCE ORDER |
| The electrofan |
| 1. Disconnect from the fan a conducting socket, having raised a latch uvula. |
| 2. Check up the electric motor for what connect it directly to the battery. Check up rotation freedom крыльчатки, having convinced that the engine has cooled down. |
| 3. For check of thermoswitches перемкните their conclusions to the disconnected socket. The fan should rotate with high or low speed, depending on that what chain is closed by the checked gauge. On a part of cars it is necessary to include ignition. |
| 4. If feed circuits are perfectly in order, but faults in fan work thermoswitches replace are observed, having merged a liquid. If thermoswitches are serviceable, but the fan does not work, check up a safety lock, the relay and conducting. |
| The mechanical fan included гидромуфтой |
| 5. Disconnect the battery from weight, having accepted safety measures. |
| 6. On the cold engine check up presence of a weakness in resistance to rotation крыльчатки. |
| 7. At detection подтеканий муфту replace. |
| 8. Resistance to rotation крыльчатки should increase considerably on the heated-up engine (disconnect the battery from weight). Otherwise муфту replace. |
|
Removal and installation
| PERFORMANCE ORDER |
| The electrofan |
| 1. Disconnect the battery from weight. |
| 2. Remove a forward lattice (subsection 12.7 see). |
| 3. Remove a fan arm, a radiator, turn away bolts of fastening of the condenser of the conditioner (from a highway not to disconnect) and submit the condenser forward. |
| 4. Disconnect a socket and remove the fan. |
| 5. Assemblage is carried out upside-down. |
| The mechanical fan included гидромуфтой |
| 6. Disconnect the battery from weight and remove a fan casing. |
|
|
| 7. Turn away a nut (with the left carving!) fastenings гидромуфты рожковым a key on 32. For отворачивания nuts sharply strike on a key And a hammer through the extension piece of Century |
|
8. Get муфту, крыльчатку and a casing. If necessary remove a pulley from the platen of the pump of a cooling liquid, having turned away 4 bolts. |
| 9. Check up a condition крыльчатки, if necessary replace, having turned away bolts and having removed it with муфты. Муфту it is necessary to store downwards the party turned to a radiator. |
|
10. Assemblage is carried out upside-down. |
