Radiator (In Tank Oil Cooler) Installation Note

2. Follow the instruction in the manufacturers publication for flushing operation.

Oil Hose Installation Note

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

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





3. Install the hose clamp onto the hose. If reusing the hose, install the new hose clamp exactly onto the mark left by the previous hose clamp.
4. Verify that the hose clamp does not interfere with any other parts.
