REMOVAL

WARNING:

Do not remove the radiator cap when the engine is hot. Serious burns could occur from high pressure
engine 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:

Perform when the engine is cold.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-
ing.

INSTALLATION

Note the followings and installation is in the reverse order of removal.
NOTE:
Write down the serial number of the new transaxle assembly.

CAUTION:

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

re-assembly

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

train components.

• Do not reuse O-rings or copper sealing washers.
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure

to confirm the tightening torque of the crankshaft pulley bolt. Refer to 

EM-67, "Exploded View"

(MR20DD), 

EM-210, "Exploded View"

 (QR25DE).

• After converter is installed to drive plate, rotate crankshaft several turns to check that CVT rotates

freely without binding.

• When installing the CVT to the engine, align the matching mark on the drive plate with the matching

mark on the torque converter.

• When installing the drive plate to torque converter nuts, tighten them temporarily. then tighten the nuts to the

specified torque.

• Install the transaxle assembly and engine assembly mounting bolts according to the following standards.
