Coolant change (40,000 km/24 months)

Coolant drain

Attention! The coolant is changed on a cold engine. Avoid getting coolant on painted surfaces of the body and clothing. Otherwise, wash the area where the coolant has entered with plenty of water.

1. Set the knob that controls the temperature in the passenger compartment to the maximum temperature position.

2. Remove cap from expansion tank.

3. Install a container to collect coolant under the radiator.



4. If present, unscrew the plug (arrow) at the bottom of the radiator or loosen the clamp and remove the hose from the radiator base and drain the coolant into a container.





5. To drain the fluid from the cylinder block, it is necessary to unscrew the bolt plug (indicated by an arrow) from the front side of the cylinder block (left - OHV engine, right - CVH engine).


6. After draining the coolant, install the hose on the radiator and secure it with a clamp, and also 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 channels of the system. The radiator must be flushed regardless of the engine.

Flushing the radiator

1. Disconnect hoses from 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 it is not possible to flush the radiator with clean water, then a detergent must be used.

Filling the cooling system

1. Before filling the cooling system, check that all hoses inside are in good condition. Note that the antifreeze mixture must be used all year round to prevent corrosion.

2. Remove cap from expansion tank.

3. Prime the cooling system by slowly pouring coolant into the thermostat housing neck to prevent air pockets from forming. On later models, add coolant to the expansion tank.

4. If the coolant was changed, then first pour 2 liters of clean water into the expansion tank, then pour the required amount of antifreeze concentrate and the rest of the water.

5. Bring the coolant level in the expansion tank 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 tightness of the cooling system.

Antifreeze

Antifreeze is a mixture of distilled water and ethylene glycol concentrate. Antifreeze protects 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%.
