OIL COOLER FLUSHINGA6E571419900202
Caution
•Power flushing should be performed very carefully when removing the accumulated debris from
the fluid baffle, otherwise the debris cannot be removed or the problem becomes even worse.
Note
•The contaminated cooler line (oil pipes and hoses) and auxiliary cooler (if equipped) must be flushed
completely when ATX is overhauled or replaced.
•Performing back and reverse power flushing two times each does not work because debris or particles
flow out from the feed pipe side of ATX.
Recommended power-flushing manufacturer
Power Flushing
Repair procedure
1. Before power flushing, inspect the hoses/lines and clamps. Power flushing must begin with back flushing
followed by forward flushing to quickly dislodge the restriction. If back flushing is not performed before forward
flushing, the restriction could further reduce the ATF flow through the internal mesh type baffle of the cooler and
flushing will not be effective or possible.
Inspecting oil lines & clamps
1. Be sure to inspect the lines (hoses/pipes) for cuts, crimps (pinched), cracks or any other damage before
reusing them. If any problem exists replace it.
Caution
•Always use new clamps when replacing hoses.

Back flushing
1. Using the power flushing equipment
manufacturer's instructions, connect equipment
so the flushing fluid flows in the opposite direction
of normal fluid flow.
2. Flush oil cooler/lines until discharge fluid is clean.
Caution
•If the cooler can not be properly flushed
using recommended equipment, send the
radiator out for sublet cleaning or
replace.
Forward flushing
1. Connect power flushing equipment so the flushing
fluid flows in the direction of normal fluid flow.
2. Flush oil cooler/lines until discharge fluid is clean.

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
• The flushing must be performed after installation of the overhauled or replacing transaxle.
2. Follow the instructions in the manufacturer’s publication for flushing operation.

Oil Pipe, Hose Clamp, Oil Hose Installation Note
1. Apply compressed air to cooler-side opening, and
blow any remaining grime 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 hose onto the oil
pipe until it is fully seated as shown.
Note
•If reusing the hose, install the new hose
clamp exactly on the mark left by the
previous hose camp.Then apply force to the
hose clamp in the direction of the arrow in
order to fit the clamp in the place.
3. Install the new hose clamp onto the hose.
4. Verify that the hose clamp does not interfere with
any other components.

3. Pivot the screwdriver to pry the tab away from the
tank and repeat the procedure for each tab.
4. Remove the radiator outer 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 outer tank for warping. If it is
warped, replace radiator tank.
Radiator Outer Tank (In Tank Oil 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

Drive Plate Mounting Bolts Removal Note
1. Set the SST or equivalent against the drive plate.
2. Remove the bolts and the drive plate.
Drive Plate Installation Note
Caution
•If the bolts are reused, remove the oil sealant from the bolt threads. Tightening a bolt that has old
sealant on it can cause thread damage.
1. Remove the sealant from the bolts hole in the crankshaft and from the drive plate mounting bolts.
Note
•If all the previous sealant cannot be removed from a bolt, replace the bolts.
•Do not apply sealant if a new bolts is used.
2. Install the drive plate.
3. Install the adapter.
4. Apply sealant to the drive plate mounting bolts and install them.
5. Set the SST or equivalent against the drive plate.
Caution
•When installing sealant covered bolts, tighten them immediately. Leaving these bolts in a half
installed condition could cause them to be stuck that way, due to the natural hardening or the
sealant.
6. Tighten the drive plate mounting bolts in two or
three steps in the order shown.
