Removal and Installation

Warning:

Do not remove the radiator cap when the engine is hot. Serious burns could occur from high pressure coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by turning it all the way.

CAUTION:

Do not reuse CSC (Concentric Slave Cylinder). The CSC (Concentric Slave Cylinder) slides back to the original position every time the transaxle assembly is removed. This action may allow dust or contaminants to gather on the sliding parts and damage a seal of CSC (Concentric Slave Cylinder) causing clutch fluid leakage.

Note:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

REMOVAL

Shift the shift lever to the neutral position.

Remove the engine assembly together with transaxle assembly from the Nissan Sentra vehicle. Refer to Removal and Installation.

INSTALLATION

CAUTION:

• When replacing an engine or transaxle you must make sure any dowels are installed correctly during re-assembly

• The transaxle assembly must not interfere with the wire harnesses and clutch tube.

• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive train components.

• When installing transaxle assembly, do not bring input shaft into contact with clutch cover.

• Tapping work for tapping bolts is not applied to new transaxle case. Do not perform tapping by other than screwing tapping bolts because tapping is formed by screwing tapping bolts into transaxle case.
