Draining the coolant
Attention! Replace the coolant on a cold engine. Avoid getting coolant on painted surfaces of the body and clothing. Otherwise, wash the area where the coolant has come into contact with plenty of water.
1. Set the knob that controls the temperature in the car's interior to the maximum temperature position.
2. Remove the cap from the expansion tank.
3. Place a container under the radiator to collect the coolant.
4. If present, unscrew the plug (indicated by the arrow) at the bottom of the radiator or loosen the clamp and remove the hose from the base of the radiator and drain the coolant into a container.
5. To drain the fluid from the cylinder block, unscrew the plug bolt (indicated by the arrow) from the front side of the cylinder block (on the left - OHV engine, on the right - CVH engine).
6. After draining the coolant, install the hose on the radiator and secure it with a clamp, and screw the plug bolt into the cylinder block.
Flushing the cooling system
The coolant must be changed periodically, and the cooling system must be flushed, as rust and dirt form in the system channels. The radiator must be flushed independently of the engine.
Radiator flushing
1. Disconnect the hoses from the radiator.
2. Insert the hose into the inlet of the upper radiator tank, turn on the water and flush the radiator until clean water appears from the lower radiator tank.
3. If you cannot flush the radiator with clean water, you must use a detergent.
Filling the cooling system
1. Before filling the cooling system, check that all hoses inside are in good condition. Note that the antifreeze mixture should be used all year round to prevent corrosion.
2. Remove the cap from the expansion tank.
3. Fill the cooling system by slowly pouring coolant into the neck of the thermostat housing to prevent air locks. On later models, pour coolant into the expansion tank.
4. If the coolant was replaced, first pour 2 liters of clean water into the expansion tank, then pour in the required amount of antifreeze concentrate and the remaining water.
5. Bring the coolant level in the expansion tank up to the MAX mark and screw on the expansion tank cap.
6. Start the engine and warm it up to operating temperature.
7. Stop the engine and cool it down, then check the coolant level.
8. Check the cooling system for leaks.
Antifreeze
Antifreeze is a mixture of distilled water and ethylene glycol concentrate. Antifreeze provides protection for the cooling system from corrosion and increases the boiling point of the coolant. The amount of ethylene glycol in antifreeze depends on the weather conditions of the car and ranges from 40 to 70%.
