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.
