After the first 2000 km of a new car, it is necessary:
- check the tightness of the system;
- tighten the fastenings of units and devices; check the operation of the thermostat;
- adjust engine crankshaft speed at idle with exhaust gas toxicity control;
- check the operation of the forced idle economizer and the carburetor starting device.
Every 15,000 km of mileage it is necessary:
- check the operation of the thermostat;
- replace fine fuel filter;
- check the tightness of the connections;
- replace air filter element (when operating in dusty conditions, change after 10,000 km of run);
- adjust engine idle speed with exhaust gas toxicity check;
- check the operation of the forced idle economizer and the carburetor starting device.
Tighten the fastenings of units and devices every 30,000 km.
Every 45,000 km of mileage it is necessary:
- wash and blow out the carburetor parts;
- adjust the fuel level in the carburetor float chamber.
Due to the use of complex technological equipment, it is recommended that engine idle speed adjustment, checking the operation of the thermostat, forced idle economizer and carburetor starting device be performed only at vehicle service stations.
Checking the tightness and tightening the fastening of units and devices
Check the fuel system for leaks by visual inspection. Tighten the screw clamps of all hoses in the system. If damage is found to fuel lines, hoses or instruments, replace them with new ones. Carefully inspect the fuel tank along the joint line of the half-housings. If a leak is found, solder it with soft solder. You can solder only a well-washed and steamed tank that does not contain gasoline vapors to prevent their ignition during soldering. Tighten the fastenings of the fuel system instruments. Tighten the carburetor fastening nuts only on a cold engine.
Checking the operation of the thermostat
Check the position of the damper on the removed thermostat at temperatures of +25 and 35°C. In the first case, the damper should completely block the cold air supply pipe, in the second case, block the heated air pipe. If this is not the case, adjust the position of the damper by rotating the thermal power element and repeat the check. Upon completion of the check, seal the thermostat by applying enamel to the rod of the thermal power element.
Replacing the air filter element and fine fuel filter
To replace the air filter element, press the spring latches of the cover, unscrew the fastening nut and remove the filter cover. Replace the filter element with a new one and install the cover so that the arrows on the air intake pipe and on the cover itself are directed towards each other. This installation is necessary to reduce intake noise.
To replace the fine fuel filter with a new one, loosen the tightening screw clamps of the hoses on which the filter is installed. When installing the filter, pay attention to the direction of the arrow on the filter housing. The arrow should point in the direction of fuel flow (to the fuel pump).
When replacing the fine filter, take precautions to prevent gasoline from getting into the engine compartment and onto the components and parts.
