OIL COOLER FLUSHING

A3U051719900W01

Note

•

The contaminated cooler line (oil pipes and hoses) and auxiliary cooler (if equipped) must be flushed 
completely when ATX is overhauled or replaced.

1. Remove the two oil cooler line hoses and apply 

air pressure of 200 kPa {2.0 kgf/cm

2

, 28 psi} 

from the return hose (pipe) side.

•

If there is no ventilation, flush the oil cooler 
lines using the power-flushing tool. (See 05–
17–40 Power Flushing)

•

If there is ventilation, go to next step.

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.

Recommended Power-flushing Manufacturer

2. Carry out the followings steps.

(1) Remove the oil pan and inspect the fluid filter 

element from the front filter.

•

If the element is covered with too much 
debris or particles and cannot be seen, 
replace the oil cooler. (See 05–17–41 OIL 
COOLER REMOVAL/INSTALLATION.)

•

If the element can be seen, flush the oil 
cooler lines using the power-flushing tool.

Note

•

Performing back and reverse power flushing 
2 times each does not work because debris 
or particles flow out from the feed pipe side 
of ATX.

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 problems exist, replace hoses and/or pipes.

Caution

••••

Always use new clamps when replacing hoses.
