Removal
Note. Use fender covers to avoid damaging painted surfaces. To avoid damage, unplug the wiring connectors carefully while holding the connector portion. To release the fuel system pressure before removing the engine assembly, start the engine with the fuel pump relay removed. And then turn off the ignition switch after engine stops.
Information

Installation
Installation is in the reverse order of removal.
Add all the necessary fluids and check for leaks. Connect GDS. Check for codes, note, and clear. Recheck.
Note. Adjust the shift cable. Refill engine with engine oil. Refill the transaxle with fluid. Refill the engine radiator and a reservoir tank with coolant. Refill the inverter radiator and a reservoir tank with coolant. Clean battery posts and cable terminals and assemble. Inspect for fuel leakage. After assemble the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and fuel line pressurizes. Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line. Bleed air from the hybrid motor cooling system. (Refer to " COOLANT ") Bleed air from the engine cooling system. Start engine and let it run until it warms up. (until the radiator fan operates 3 or 4 times.) Turn Off the engine. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed from the cooling system. Put radiator cap on tightly, then run the engine again and check for leaks.
Note. The HCU need to learn the mesh point for the engine clutch to reduce shock while engine power is connected to the transaxle. Perform the Clutch Pressure Sensor Calibration after installing the CPS, HCU, engine or hybrid drive motor (Refer to " CLUTCH PRESSURE SENSOR CALIBRATION ").
