5. Ensure that the oil pan drain plug are firmly compressed.
Filling of the cooling system:
1. Before you begin the process, make sure the engine is completely cold.
2. Remove the cover and radiator fill the radiator with coolant up to the top of the filler hole.
The cooling fluid in the air intake before putting the plug, remove the tube from the water
outlet. Replace the air intake plug gasket with a new one. After filling the coolant and air
intake, fasten the plug fully.
3. Fasten the upper radiator hose two or three times. This motion leads to draining the air from
the hose and if the engine coolant level drops, add coolant up to the top of the filler hole of
the radiator.
4. Install and attach the radiator cap securely.
5. Fill the expansion tank until
it’s on “MAX” fill line with coolant. Replace the expansion tank
cap.
6. Switch off the water exit the pipe plug in the air intake.
7. Start the engine, leave to idle for 2 or 3 minutes, and then stop the engine.
8. After you are sure that the coolant no longer is not hot, open the radiator cap. If you manage
to drop the coolant level of the radiator fill coolant through the filler hole again. If the coolant
level is abnormally low; check for leaks in radiator, in the hose or expansion tank in the
engine cooling circuit.
9. After tightly closing the radiator cap, warm up the engine to 2,000 rpm. run at RPM.
10. When you reach the middle point of the indicator of the engine coolant temperature, leave
the engine at idle mode at an idle speed for 5 minutes and then stop the engine.
11. After you are sure that the coolant no longer is not hot, open the radiator cap, check coolant
level and if necessary, fill the coolant through the radiator filler hole. If the coolant level is
abnormally low, check for coolant leaks.
12. Shut the radiator cover tightly.
13.
Fill up until the cooling fluid in the expansion tank is on “MAX” line again and then close the
cover of the expansion tank.
radiator core cleaning:
When there is dirt or dust from clogging the air channels in the radiator core, the cooling
efficiency is compromised. This also causes radiator core to wear out. Wash the radiator core
periodically with water.
Cleaning of the coolant channels:
1. Remove the radiator cap and fill the radiator with tap water. Take the air intake plug out
before filling the coolant, remove the water outlet from the tube. After filling the water, fully
fasten the air intake plug.
