– stop the engine, let it cool down, raise the cooling uid level
in the expansion chamber to the standard and close the expansion
chamber plug;
– run 2–3 cycles of the engine warm-up — cool-down and
raise the cooling uid level again in the expansion chamber to the
standard.
To drain the uid from the engine cooling system open the expan-
sion tank plug, unscrew teh heat exchanger outlet plug 10 (Fig. 9. 5)
and unscrew cylinder head cap 14. When draining, set the additional
heater (if installed) switch 5 (Fig. 3.11) to the ON position.
The generator and cooling system pump drive belt tension
(Fig. 9.6.) is provided by an automatic tension mechanism 2.
In the operation process, the automatic tension mechanism does
not require servicing or adjustment.
Fan and steering system hydraulic pump drive belt tension 15
(Fig. 9.6) is performed by displacing pump 12, for which it is neces-
sary: to loosen bolts 13, adjust the drive belt tension by adjustment
bolt 14 and move the pump along the rails. Tighten bolts 13.
In motor vehicles equipped with an air conditioner, the aggregates
drive is performed by the same belt. Its tension is adjusted automati-
cally (Fig. 9.7). It is necessary to check belt condition during the
operation process. Upon detection of its substantial looseness, the
GUR pump placement adjustment is possible by bolt 9, to continue
using the stretched belt. The GUR pump is xed by bolts 8.
Fan drive clutch. In case the clutch does not switch on and
off properly, the engine can overheat. Check up is to be done at a
specially equipped UAZ workshop.
Keep the external surface of the clutch clean.
Electric fan is installed on the cooling system radiator assembly
at the front. It turns on and off automatically.
