Fill the engine cooling system with sodium carbonate detergent.
Note: Each 23 L of water should be mixed with 0.5 kg sodium
carbonate.
△Caution: Do not install the filler cap during cleaning the
cooling system and run the diesel engine without the cap
on the radiator.
△Caution: Air must be discharged from the cooling system
chamber when filling clean agent. First open the air
bleeding valve (if applicable) in the intercooler, and slowly
fill the detergent to avoid air block. Wait for 2 to 3 minutes
to allow air to be exhausted fully. The detergent must be
filled until it reaches the bottom of the coolant filler port or
the inspection port.
Start the engine and run it for 5 minutes after the coolant
temperature goes higher than 80C. Stop the engine and
discharge all detergent.
