Draining liquid
Drain the liquid in the following order:
- let the engine cool down;
- set the heater switch to the maximum heating position;
- open the cap of the expansion tank;
- install a 6–7 l container under the lower radiator hose;
- remove the protective casing of the engine;
Open the cap of the expansion tank.
Disconnect the hose from the lower radiator hose and drain the fluid into a suitable container.
Connect the hose to the lower radiator hose. Flush the cooling system if necessary.
Attention! Do not allow liquid to come into contact with the skin, in case of contact, wash the liquid off the body with plenty of water.
Flushing the radiator
Operating procedure:
- disconnect the upper and lower hoses from the radiator;
- insert a suitable hose connected to the water supply into the upper radiator connection and flush it until clean water flows from the lower connection. If necessary, apply a detergent additive, which can be purchased at an auto shop. You can also flush the radiator in the opposite direction, for which you will have to insert a hose with water into the lower pipe;
- connect the hoses to the radiator.
Engine flush
Operating procedure:
- wrap the drain plug in the cylinder block;
- disconnect the lower hose from the radiator;
- remove the thermostat from the housing (see below) and temporarily install the housing nozzle in its place;
- insert the hose connected to the water supply into the thermostat nozzle and flush the engine water jacket until clean water flows from the lower hose;
- install the thermostat, connect the lower hose to the radiator.
Filling the system with coolant
Pour coolant into the system through the filler neck of the expansion tank.
Attention! (K4J engine) When filling the system with liquid, be sure to open the bleed valve located on the thermostat unit.
Location on the thermostat housing of the sensor (1) coolant and fitting temperatures (2) to remove air (K4J engine)
- A) Close the air bleeder when the liquid begins to flow out in a continuous stream.
- b) Start the engine (2500 rpm).
- V) Add fluid to the expansion tank to the level of the upper edge of the neck for about 4 minutes.
Close the cap of the expansion tank.
Start the engine and run it at 2500 rpm for four minutes. Check the fluid level in the expansion tank. Close the expansion tank cap.
Let the engine run for 20 minutes at 2500 rpm before turning on the electric fan (the specified time is required for automatic degassing of the coolant). Make sure the fluid level in the reservoir is near the mark "Maxi".
Attention! (K4J engine) Do not open the bleed valve while the engine is running.
