How to drain the cooling system
Attention:
Do not drain the coolant while the engine is still hot and the system is under pressure because dangerous
coolant can be discharged.
1. Ensure that the machine is on level ground.
2. Remove the filter cap of the cooling system.
3. Remove the drain plug from the side of the cylinder block (A or B) in order to drain the engine. Ensure that the
drain hole is not restricted.
4. Open the tap or remove the drain plug at the bottom on the radiator in order to drain the radiator. If the radiator
does not have a tap or drain plug, disconnect the hose at the bottom of the radiator.
5. If the lubricating oil cooler (C) is installed the cover of the filter but on the cylinder body, it must be drained and
flushed. For this, disconnect the hoses (C1, C2) on the top of the cooler and flush it by connecting to a tap (C1)
until clean water flow out of the inlet (C2).
Attention
： ： ： ：
If the cooling system will not be instilled after flushing, then draining the lubricant oil cooler and instill
165ml (1/3 pints) antifreeze. When the vehicle moving, if water flowing out then this method can prevent freezing.
6. If necessary, flush the system with clean water
7. Install the hose onto the top of the cooler and fasten the clamp.
8. Fit the drain plugs and the filler cap. Close the radiator tap or connect the radiator hose.
9. As for some engine types for agriculture use, one of the cylinder plugs on the cylinder sides are modified into a
switch controlling water release, so as to empty coolant and be suitable for specific agricultural environment.
