| REMOVAL SERVICE POINTS
| <<A>> CRANK ANGLE SENSOR CONNECTOR REMOVAL
| CAUTION Do not remove the tape securing the crank angle sensor connector and control wiring harness, since the control wiring harness may contact the power steering oil pump pulley.
| <<B>> DRIVE BELT REMOVAL The following operations will be needed due to the introduction of the serpentine drive system with the drive belt auto-tensioner.
| Securely insert the spindle handle or ratchet handle with a 12.7 mm insertion angle into the jig hole of the auto-tensioner. Rotate the auto-tensioner anti-clockwise and align hole A with hole B. CAUTION To reuse the drive belt, draw an arrow indicating the rotating direction (clockwise) on the back of the belt using chalk, etc.
| Insert an L-shaped hexagon wrench, etc. into the hole to fix and then remove the drive belt.
| <<C>> A/C COMPRESSOR AND CLUTCH ASSEMBLY/POWER STEERING OIL PUMP ASSEMBLY REMOVAL With the hose installed, remove the A/C compressor and clutch assembly, and power steering oil pump assembly from the bracket. NOTE: Secure the removed A/C compressor and clutch assembly, and power steering oil pump assembly with cord or rope at a position where they will not interfere with the removal of the engine assembly.
| <<D>> TRANSMISSION ASSEMBLY REMOVAL
| Pre-tighten the 2 bolts on the car to assemble the radiator support upper insulator to set the special tools engine hanger MB991895 or engine hanger MB991928. Remove the transmission assembly [Refer to GROUP 23A, Transmission Assembly <4G63> , Refer to GROUP 23A, Transmission Assembly <4G64> .]
| <<E>> ENGINE MOUNTING INSULATOR REMOVAL Support the engine with a garage jack. Remove the following special tool.
| <Special tool engine hanger (MB991895) is used> Remove special tool MB991895.
| <Special tool engine hanger (MB991928) is used> Remove special tool MB991928.
| Hold the engine assembly with a chain block, etc. Place a garage jack against the engine oil pan with a piece of wood in between so that the weight of the engine assembly is no longer being applied to the engine mounting insulator. Loosen the engine mounting insulator mounting nuts and bolt, and remove the engine mounting insulator.
| <<F>> ENGINE ASSEMBLY REMOVAL After checking that all cables, hoses and wiring harness connectors and so on are disconnected from the engine, lift the chain block slowly to remove the engine assembly upward from the engine compartment.
| INSTALLATION SERVICE POINTS
| >>A<< ENGINE ASSEMBLY INSTALLATION
| Install the engine assembly, being careful not to pinch the cables, hoses or wiring harness connectors.
| >>B<< ENGINE MOUNTING INSULATOR INSTALLATION Place a garage jack against the engine oil pan with a piece of wood in between, and install the engine mounting insulator while adjusting the position of the engine. Support the engine assembly with a garage jack. Remove the chain block. Use the following special tool as during removal to support the engine.
| <Special tool engine hanger (MB991895) is used> Set special tool MB991895. [Refer to GROUP 23A, Transmission Assembly <4G63> , Refer to GROUP 23A, Transmission Assembly <4G64> .]
| <Special tool engine hanger (MB991928) is used> Set special tool MB991928. [Refer to GROUP 23A, Transmission Assembly <4G63> , Refer to GROUP 23A, Transmission Assembly <4G64> .]
| >>C<< SELF-LOCKING NUTS INSTALLATION CAUTION Do not tighten the self-locking nuts while the engine is hot. Tighten the self-locking nuts to the specified torque while the engine is cold. Tightening torque: 45 ± 5 N·m
| >>D<< TRANSMISSION ASSEMBLY INSTALLATION Install the transmission assembly [Refer to GROUP 23A, Transmission Assembly <4G63> , Refer to GROUP 23A, Transmission Assembly <4G64> .]
| Remove from the car the 2 bolts, to assemble the radiator support upper insulator.
| >>E<< O-RING/FUEL HIGH-PRESSURE HOSE INSTALLATION CAUTION Do not let any engine oil get into the delivery pipe. Apply a small amount of new engine oil to the O-ring. Turning the fuel high-pressure hose to the right and left, install it to the delivery pipe, while being careful not to damage the O-ring. After installing, check that the hose turns smoothly. If the hose does not turn smoothly, the O-ring is probably being clamped. Disconnect the fuel high-pressure hose and check the O-ring for damage. After this, re-insert it to the delivery pipe and check that the hose turns smoothly. Tighten the fuel high pressure hose mounting bolts to the specified torque. Tightening torque: 5.0 ± 1.0 N·m
