Radiator (In Tank Oil Cooler) Installation Note
1. The automatic transaxle oil cooler flushing must be performed whenever a transaxle is removed for service to remove existing fluid, which may be contaminated to prevent contamination of new fluid. The flushing must be performed after installation of the overhauled or replacement transaxle.
2. Follow the instruction in the manufacturer's publication for flushing operation.

0il Pipe Installation Note

Caution: In order to prevent ATF leakage, replace the hose when any damages are found inside or outside of the hose, especially on areas contacting with pipes.





1. Apply compressed air to cooler-side opening, and blow any remaining dust and foreign material from the cooler pipes. Compressed air should be applied for no less than one minute.





2. Align the marks, and slide the oil cooler hose onto the oil cooler pipe until it is fully seated as shown.

4. Verify that the hose clamp does not interfere with any other parts.
