- fill the radiator with the cooling fluid to the level of
10-15 mm below the throat, and the expansion chamber to the
level of 3-4 cm above the mark "min";
- start the engine, add the cooling fluid to the radiator upper
tank when its level decreases, and close the radiator plug;
- stop the engine, let it cool down, raise the cooling fluid
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
again raise the cooling fluid level in the expansion chamber to
the standard.
The fluid shall be drained from the engine cooling system
through two holes closed with plugs 11 and 14 (Fig. 9.5). During
draining, the interior heater valve actuating lever 2 must be
switched to the position "open".
The steering booster fan and pump drive belt 14 (Fig. 9.6) are
tensioned by the pump 13 displacement, for which the following
must be done: loosen bolts 11, adjust the belt tension using
adjustment bolt 12, while moving the pump along the bracket,
and tighten bolts 11.
The cooling system and engine generator drive belt 3 (Fig.
9.6) tension is ensured by the automatic belt tensioner. No belt
tension adjustment is required during operation.
To check the automatic tensioner condition, check smoothness
of motion of the lever with the tensioner roller from one extreme
position to another, with the belt removed. In case of jamming,
replace the belt tensioner mechanism.
The fan drive clutch. If the clutch no longer engages or
engages incompletely, the engine can overheat. The clutch
condition must be checked at UAZ Service Stations possessing
the dedicated equipment.
Keep the external surface of the clutch clean.
During the operation, you must monitor the distance between
the fan blades and the radiator upper tank, as well as the distance
between the clutch and the radiator core, the distance shall be
equal to at least 15 mm.
