Egr Cooler (W/O Glow Plug Controller) -- Removal |
- NOTICE:
- 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.
- After removing the injection pipes, clean them with a brush and compressed air.
| 1. PRECAUTION |
- NOTICE:
- After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work (HILUX_TGN26 RM000004QR1003X.html).
| 2. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL |
- NOTICE:
- When disconnecting the cable, some systems need to be initialized after the cable is reconnected (HILUX_TGN26 RM000004QR3003X.html).
| 3. DRAIN ENGINE COOLANT |
- CAUTION:
- Do not remove the radiator reservoir cap 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.
- HINT:
- Collect the coolant in a container and dispose of it according to the regulations in your area.
Drain the coolant by removing the radiator reservoir cap and, using a wrench, remove the vent plug.
