CAUTION / NOTICE / HINT
The necessary procedures (adjustment, calibration, initialization, or registration) that must be performed after parts are removed, installed, or replaced during the fuel supply pump assembly removal/installation are shown below.
| Replacement Part or Procedure | Necessary Procedures | Effects/Inoperative when not Performed | Link |
|---|---|---|---|
| Fuel supply pump assembly | Supply Pump Initialization | Engine startability | |
| Timing belt | Mode reset operation |
|
CAUTION:
Do not remove the radiator reservoir cap sub-assembly, vent plug, radiator drain cock plug while the engine and radiator assembly are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
To prevent injury due to contact with an operating fan and generator V-belt or cooling fan, keep your hands and clothing away from the fan and generator V-belt and cooling fans when working in the engine compartment with the engine running.
To prevent burns, do not touch the engine, exhaust manifold or other high temperature components while the engine is hot.
Note
When replacing the parts in the following chart (A), replace the No. 1 injection pipe sub-assembly, No. 2 injection pipe sub-assembly, No. 3 injection pipe sub-assembly, No. 4 injection pipe sub-assembly and/or fuel inlet pipe sub-assembly with new ones.
After removing the No. 1 injection pipe sub-assembly, No. 2 injection pipe sub-assembly, No. 3 injection pipe sub-assembly, No. 4 injection pipe sub-assembly and fuel inlet pipe sub-assembly, clean them with a brush and compressed air.
