Radiator (In Tank Oil Cooler) Installation Note

1.  The automatic transaxle oil cooler flushing must be performed whenever a transaxle is removed for service because the existing fluid may be contaminated, and to prevent contamination of new fluid.

Note
•  Flushing must be performed after installation of an overhauled or replaced transaxle.

2.  Follow the instructions in the manufacturer’s publication for flushing operation.


Oil Pipe, Hose Clamp, Oil Hose Installation Note

1.  Install the oil hose to the oil pipe while being careful of the following:

(1)  Align the marks on the hose and the pipe so that they are in a straight line.

(2)  The marks on the hose and the pipe are within range A shown in the figure.
(3)  Insert the hose until it contacts the edge of the spool of the pipe.
(4)  If the hose does not insert easily, use ATF as a lubricating agent.
(5)  Wipe off the ATF remaining on the hose and pipe after installing the hose.
(6)  The hose clamp is within the marked area of the hose.

(7)  The hose clamp installation direction is within range B shown in the figure.
Note
•  If the oil hose is to be re-used, install the hose clamp to the impression in the hose left by the previous installation. After installation, apply force to the hose clamp in the direction of the arrows to engage the hose clamp securely.
