Note
When replacing the injectors (including shuffling the injectors between the cylinders), common rail or cylinder head, it is necessary to replace the injection pipes with new ones.
When replacing the fuel supply pump, common rail, cylinder block, cylinder head, cylinder head gasket or timing gear case, it is necessary to replace the fuel inlet pipe with a new one.
DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM (w/ Air Conditioning System)
Start up the engine.
Turn the A/C switch on.
Operate the cooler compressor at an engine rpm of approximately 1,000 for 5 to 6 minutes to circulate the refrigerant and collect compressor oil remaining in each component into the cooler compressor as much as possible.
Stop the engine.
Using SST, let the refrigerant gas out.
DRAIN ENGINE COOLANT
CAUTION:
Do not remove the radiator reservoir cap sub-assembly while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Loosen the radiator drain cock plug.
| *1 | Bleeder Plug | *2 | Radiator Reservoir Cap Sub-assembly |
| *3 | Radiator Reservoir Assembly | *4 | Cylinder Block Drain Cock Plug |
| *5 | Radiator Drain Cock Plug | - | - |
Remove the radiator reservoir cap sub-assembly.
Loosen the cylinder block drain cock plug (on the engine oil cooler cover), and drain the engine coolant.
Tighten the radiator drain cock plug.
Tighten the cylinder block drain cock plug (on the engine oil cooler cover).
DRAIN ENGINE OIL
Remove the oil filler cap.
Remove the oil pan drain plug and gasket, and then drain the engine oil into a container.
Wipe the oil pan and oil pan drain plug.
Install a new gasket and the oil pan drain plug.
