Overhaul Info
Caution:
.If the radiator cap is opened when the coolant temperature is above 100degrees(C),the pressure of coolant
temperature will go down and get boiled rapidly. The steam jet may cause danger and injury. Cover the cap
with a piece of cloth after the coolant temperature goes down and open the cap.
.Inspection of coolant should be done after the coolant is fully cooled.
.Coolant is poisonous. Do not drink or splash it to skin,eye or cloth.
