3.6.7.3. The fan with the viscous coupling / the fan coupling
The coupling of the fan should be replaced if inside the nave has a rust. The fan at a stop of the engine or stops, or very hard rotates. Replace the coupling also if there is an axial or radial side play. Turn the fan for check of a side play forward and back, the notable side play should not be. Also from a nave oil should not act.
Removal
| PERFORMANCE ORDER |
| 1. Remove the lower guard of a motive compartment. |
|
2. Unscrew the fan by means of a wrench of 32 mm in size from a nave of the pump of cooling liquid. |
Prevention
The nut has the left carving therefore it is necessary to turn it to the right (clockwise).
|
|
3. When unscrewing a nut press maple a pump belt, having hooked thus on a nave in order that it was not turned. In workshops of OPEL use the special KM-821 (1) tool which presses maple a belt to a bolt head, adaptation it is also possible to make independently of a tin. |
| 4. After easing the nut can be unscrewed rotating a krylchatka of the fan further. Pay at the same time attention to that the krylchatka of the fan did not fall down. |
| 5. Take out the fan down. |
Prevention
Do not put in horizontal position the fan with the viscous coupling, put only vertically.
|
| 6. If it is necessary, separate a krylchatka of the fan and the coupling of the fan, unscrew 3 bolts of fastening. |
|
Installation
| PERFORMANCE ORDER |
| 1. Install the viscous coupling in the fan and fix by fastening bolts with effort 10 N. m. |
Prevention
Not to damage a coupling carving, it is impossible to tighten fastening bolts strongly.
|
| 2. Screw the fan with the installed coupling on a pump nave with 20 N.' effort of m, holding at the same time a nave. |
Prevention
Do not warp a nut. The nut has the left carving, roll to the left.
|
| 3. Establish the lower guard of a motive compartment. |
