Face-to-face part of the car (6) result in position for service (the basic stages of work): the special tool (8) screw up in apertures (5), for this purpose unscrew on the right a bolt (2). Unscrew bolts 1, 3, 4. Pull a face-to-face part approximately on 70 mm forward and this time screw up bolts 4 in forward carving apertures 7.


Reduction of a face-to-face part of the car in position for service: it is pushed forward on distance from a bolt 1 to a bolt 2. Then the bolt 1 is screwed up in apertures of a bolt 2.


Reduction of a face-to-face part of the car in position for service: by figure "2" the screwed up special tool 3369 consisting of a long bolt and a pipe is shown. Figures "1", 3, 4 and 5 designate bolts which should be weakened for displacement of a face-to-face part.


The rear view of the dismantled lattice of radiator А4:

1 and 2 – fixing clamps on an upper edge;
3 and 4 – directing on a bottom edge.

Reduction of a face-to-face part of the car in position for service
