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.

should be applied for no less than 1 min.

2. Align the marks, and slide the oil hose onto the oil
