Cooling system – liquid, with a forced circulation closed. Radiator cap has two valves are not allowed in the cooling system to excessive pressure or vacuum. When closed valves, the system is pressurized. When you open the radiator cap beware of scalding. The normal water temperature in the engine cooling system 80-90 C.
The water temperature is controlled by the pointer temperature, which is located on the dashboard, and its sensor installed in the cylinder head. Cooling system should be refilled and clean as possible “soft” water that has low salt content. When properly meshing of bevel gears with spiral teeth backlash in the general part of the tooth is 0,15-0,4 mm. The differential consists of a demountable boxes, which are placed two conical poluosevye gears, spider and four satellite. The differential is set on tapered roller bearings, located in split bearings with lids, which are processed in conjunction with the sump of the main gear. Bearings regulate the nuts without any noticeable axial clearance, but without the tightness. To fix the nuts on the bearing caps are stoppers Service axle is lubricated, according to the map lubrication, inspection at 1000 hours tightening nut flange leading pinion nuts cups differential. Tightening torque of nuts flange should be 20-25 kg-m, and torque nuts cups differential 11.8 kg-m.
