Bleeding 1. Loosen the bleeding screw on the overflow valve of injection pump. 2. Operate the priming pump until the fuel with foam flows out of the bleeding screw. 3. Tighten the bleeding screw. 4. Repeatedly operate the priming pump and verify there is no fuel leak. 1.4.4 Cooling system Coolant level Check the coolant level. If necessary, fill in the radiator reservoir. If the coolant level falls under carefully check whether there is a leakage in the cooling system. And then, fill in the coolant until it reaches Reservoir Note: Never make a reservoir overflow. The radiator filler cap should be opened only if it is very necessary.
Coolant level check can only be performed when the engine is cold. For mixing ratio between the cooling water and anti-freezer, please refer to the left figure. Long life coolant Freezing point ( C) Mixing ratio (%) Cooling System Check Place an American tester for radiator filler on the radiator. Apply test pressure on the cooling system and check the leakage. The test pressure shall not exceed the specified pressure. Test pressure: 196kPa 30
