Removal


Prevention

On models with petrol engines for fastening of a pulley of the fan of a radiator to an arm it is necessary to use the special tool. In house conditions the tool can be made of a steel wire in diameter of 4 mm. Use of independently made tool on models with diesel engines is not recommended not to damage a pulley of the fan of a radiator and the related elements.


Use of the special tool for fixing of a pulley of the fan of a radiator from a provorachivaniye

Unscrewing of bolts of fastening of a krylchatka of the fan of a radiator

Removal of a krylchatka of the fan of a radiator from the coupling

Unscrewing of the central bolt of fastening of the coupling of the fan of a radiator

Removal of the coupling of the fan of a radiator

Removal of laying from a pulley of the fan of a radiator
After unscrewing of bolts of fastening remove laying from a pulley of the fan of a radiator.

Removal of a pulley of the fan of a radiator

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator and an auxiliary driving belt.
2. Unscrew screws and remove the plastic casings located from above and under a radiator. At existence take a hose of cooling liquid from a fastening bracket on the top casing.
3. On models with a casing of the fan of a radiator in the form of one detail remove metal spring brackets and disconnect a casing from a radiator. Remove a casing from the fan and arrange it between the engine and a krylchatka of the fan.
4. At existence remove a clamp, turn directing casing to the left and remove it from a casing of the fan of a radiator. Arrange a directing casing between the engine and a krylchatka of the fan of a radiator.
5. Remove metal brackets, disconnect a casing of the fan of a radiator from a radiator and take it from a motor compartment together with a directing casing.
6. On models with the petrol engine turn a pulley of the fan of a radiator in such situation while the blocking opening on a pulley will not be combined with dredging in an arm. For pulley fixing from a provorachivaniye insert the special tool or a steel core in diameter of 4 mm through an opening in a pulley (see fig. Use of the special tool for fixing of a pulley of the fan of a radiator from a provorachivaniye).
7. On models with diesel engines for fixing of a pulley of the fan of a radiator from a provorachivaniye it is necessary to use only the special tool which grasps edge of a pulley of the fan of a radiator and an auxiliary belt.
8. Unscrew screws and remove a krylchatka of the fan of a radiator from the coupling. On models with a fan casing in the form of one detail take a casing from a motor compartment (see fig. Unscrewing of bolts of fastening of a krylchatka of the fan of a radiator, Removal of a krylchatka of the fan of a radiator from the coupling).
9. Unscrew the central bolt and remove the coupling from a pulley of the fan of a radiator. If necessary unscrew bolts and remove a pulley from a shaft (see fig. Unscrewing of the central bolt of fastening of the coupling of the fan of a radiator, Removal of the coupling of the fan of a radiator, Removal of laying from a pulley of the fan of a radiator, Removal of a pulley of the fan of a radiator).
