Flushing
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/cm2, 28 psi) from the return hose (pipe) side.
^
If there is no ventilation, flush the oil cooler lines using the power-flushing tool.
^
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.

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.
^
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.
