1. Remove the two oil cooler line hoses and apply

air pressure of 196 kPa {2.0 kgf/cm

, 28 psi}

from the return hose (pipe) side.

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.

2. If there is no air blown out the feed side, flush the

oil cooler lines using the power-flushing tool. (See

K–38 Power Flushing

)

Recommended power-flushing manufacturer

3. If there is ventilation, carry out the following steps.

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

element from the front filter.

(2) If the element is covered with too much debris

or particles and cannot be seen, replace the
oil cooler. (See

K–39 OIL COOLER

REMOVAL/INSTALLATION

.) (See

K–41 OIL

COOLER DISASSEMBLY/ASSEMBLY

(3) If the element can be seen, flush the oil cooler

lines using the power-flushing tool.

• 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.

AUTOMATIC TRANSAXLE

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 and 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 lines and clamps.

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.
