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.
