Check of serviceability and replacement of the fan of system of cooling and coupling of its coupling
|
|
In order to avoid possible damages or receiving traumas AT ALL do not start the engine with the damaged fan. Do not try to make repair of blades of the fan - in case of damage of a krylchatka replace the fan new. |
Check
|
|
- Disconnect a negative wire from the battery and shake the fan forward-back a hand, checking its coupling on existence of signs excessive люфта.
- At cold (and not started) the engine повращайте a krylchatka of the fan manually. The fan should rotate freely.
- Examine the fan outside, trying вывить traces of leakages of liquid from assembly of the vyazkostny coupling. In case of identification of signs of malfunction replace the coupling.
- At completely heated-up engine switch off ignition and disconnect a negative wire from the battery. Turn the fan manually. Appreciable resistance should be felt small, but. If the fan rotates freely, replace the coupling.

Replacement
|
|
- Disconnect a negative wire from the battery. Give fixing bolts and lift a fan casing, having bared cuts in the bottom arm of a radiator, then transfer a casing via the fan.
|
|
- Give bolts of fastening of a casing of the fan.

Details of assembly of the fan of cooling of the V8 engine |
- For fan removal on V8 engines the special tool is required, to get which it is possible almost in any of shops of automobile accessories. The fan fastens to the water pump by means of the big central nut being a part of a drive of the fan. The tool grasps four bolts of a pulley of the pump whereas the central nut is given by a big key (a carving right and to give a nut follows counter-clockwise). Sometimes the pulley of the pump can be fixed, rather strongly having pressed tape type a driving belt, however in case the fan staid on the car already long enough, use of the tool appears inevitable. The fan of the 6-cylinder engine fastens to the water pump by means of four hairpins with nuts; give nuts and remove the fan assembled with the coupling coupling from hairpins.
- Take fan assembly with the coupling and its casing from an impellent compartment.
|
|
- Take fan assembly with the coupling and a casing.
|
- Carefully survey a condition of blades of a krylchatka. In case of detection of defects make fan replacement.
- At this stage the krylchatka can be отболчена from the coupling coupling (if in it there is a need). To store the fan follows, having laid down the party turned to a radiator.
|
|
- Give four bolts and separate a krylchatka from the coupling coupling - to store the coupling follows stacking surely DOWN the party turned to a radiator.
|
- Installation make upside-down. Track reliability and uniformity of a tightening of nuts of fastening of a krylchatka and the coupling.
