Oil Cooler Removal/Installation








1. Remove in the order shown in the figure.
2. Install in the reverse order of removal.
3. Add engine coolant.
4. Add ATF to the specified level.
5. Inspect for the coolant and ATF leakage.
6. Carry out the mechanical system test.
7. Carry out the road test.

Radiator Lower Tank (In Tank 0il Cooler) Removal Note





1. Inspect the height of the header tabs.
2. Insert the end of a medium tip screwdriver between the end of the header tab and the lower tank.

Note: Do not open more tabs than necessary for tank removal.





3. Pivot the screwdriver to pry the tab away from the tank and repeat the procedure for each tab.
4. Remove the radiator lower tank and O-ring (gasket) from the core header when all of the tabs are opened.

Note: If any header tabs are missing from the core, replace the radiator.

5. Inspect the gasket surface of the radiator core header to ensure it is clean and free of foreign material or damage.
6. Inspect the radiator lower tank for warping. If it is warped, replace radiator tank.

Radiator Lower Tank (In Tank 0il Cooler) Installation Note





1. Install a new O-ring and ensure it is not twisted.

Note: The old O-ring must be replaced.

2. Position the radiator tank in the original direction to the core using care not to scratch the tank sealing surface with the header tabs.

Note: Step 3 will set jaw opening to the correct specification.





3. With the jaws of locking-type pliers (vise grips) closed and locked, turn the adjusting screw to position the jaws against the drill bit with the diameter measured (height) in removal procedure.
1. Tighten the lock nut on the adjusting screw against the handle to lock the adjustment in place.





4. Squeeze the header tabs down in order as shown against the lip of radiator lower tank base with locking-type pliers while rotating the pliers toward the tank.





5. Verify the height of the header tabs is same as the height before removal.
6. Inspect for the leakage of radiator according to the following procedure.
1) Blind the radiator inlet and outlet.
2) Blind the ATF cooler inlet and outlet.





3) Connect a radiator tester.
4) Apply pressure of 145 kPa (1.5 kgf/m2, 21 psi) and verify that the pressure is held.





5) Put the radiator into water slowly with the radiator tester connected.
6) Inspect for air leakage.

Radiator 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. The flushing must be performed after installation of the overhauled or replaced transaxle.

On Hose Installation Note





1. Apply compressed air to cooler-side opening more than one minute, and blow any remaining grime and foreign material from the cooler pipes.





2. Align the marks, and slide the oil hose onto the oil 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 on the mark left by the previous hose clamp.
^ Verify that the hose clamp does not interfere with any other components.
