Oil Cooler Flushing: Notes

WARNING: This page is about a different variant/trim than selected.

NOTE:

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

Remove the two oil cooler line hoses and apply air pressure of 196 kPa {2.0 kgf/cm² , 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 will worsen.
NOTE:
- Performing back and forward power flushing two times each does not work because debris or particles flow out from the feed pipe side of the AT.
If no air blows out of the feed side, flush the oil cooler lines using the power-flushing tool. (See POWER FLUSHING .)
