3尧 Coolant
Special coolant is needed for some vehicles. In that case, use coolant according to the
requirement of the vehicles. For general purposes, use cooling water which meets certain
requirements.
Cooling water: it's good to be rain water, tap water or clean river water. It's not good
to use well water because there are so much minerals in the water which will form scale
deposited in the cooling system which is harmful to cooling effect and may damage the
engine. It may need to add antifreeze into the cooling system to prevent water freezing in
cold winter. The most common antifreeze is glycol water solution or alcohol.
Filling coolant and precautions:
Fill cooling water up to the mark at the filler.
Pay attention to close the drain cock after water draining from it.
Tighten filler cap.
Start the engine, run it until it reaches normal working temperature
thermostat opens and the water pipe of the major circuit apparently grows warmer.
Shut down the engine after the initial operation. Let the engine cool down and check
the water level.
Caution: Be careful of not getting burnt when you open the filler cap while the water
temperature is still high.
