7. Start the engine, let it idle for 5 minutes or more and then stop the engine.
8. After checking that the engine has sufficiently cooled down, remove the radiator cap.
If the engine coolant level has decreased, replenish with engine coolant up to the
radiator filler opening. If the engine coolant level has abnormally decreased, check
for leaks from the radiator, the engine coolant passages, or the reserve tank hose.
9. After firmly closing the radiator cap, idle the engine until the needle of the coolant
temperature gauge reaches the center and the thermostat opens. In order to
save time, if the vehicle is equipped with a warm-up switch, turn the switch on to
warm up the engine. If the vehicle is not equipped with a warm-up switch,
maintain the engine speed approximately 2,000 r/min to warm up the engine. After
the needle of the coolant temperature gauge reaches the center, increase the
engine speed to approximately 2,000 r/min, and maintain this speed for 5
minutes. If the vehicle is equipped with an air conditioner, turn the A/C switch off
to facilitate warming. If the vehicle is equipped with a heater, turn off the fan to
facilitate warming. Check if the thermostat is open or not by checking whether the
upper hose and lower hose are hot. If the vehicle is equipped with a heater, turn
the temperature control to the maximum setting and make sure that hot air comes
out.
10. Let the engine idle for 5 minutes and then stop the engine.
11. After checking that the engine has sufficiently cooled down, remove the radiator
cap and check the engine coolant level. If the engine coolant level has decreased,
replenish with engine coolant up to the radiator filler opening from the radiator cap
section. If the engine coolant level has abnormally decreased, check for engine
coolant leaks.
12. Repeat steps 9 through 11 until the engine coolant level in the radiator filler opening
stops declining.
13. Firmly close the radiator cap.
14. Replenish the engine coolant in the reserve tank up to the "MAX" line, and then
close the reserve tank cap.
15. Check the engine coolant level of the reserve tank the next morning. If the engine
coolant level has decreased, refill with engine coolant to the "MAX" line.
Cleaning the Radiator Core and Intercooler Core
Cooling performance is compromised if the radiator core and intercooler core become
dusty or dirty. This can also cause corrosion of these cores. Periodically wash the
radiator core with tap water.
Be sure to stop the engine before cleaning cores. If the engine is running,
you can get entangled in the rotating components, resulting in an injury.
Do not clean cores until the engine,radiator, intercooler, and other parts
have cooled. Otherwise, you could get burned.
