OIL COOLER FLUSHING
| 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. |
Note. The contaminated cooler line (oil pipes and hoses) and auxiliary cooler (if equipped) must be flushed completely when ATX is overhauled or replaced. 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.
Scheme 247
Back Flushing
- Using the power flushing equipment manufacturer's instructions, connect equipment so the flushing fluid flows in the opposite direction of normal fluid flow.
- Flush oil cooler/lines until discharge fluid is clean.
Scheme 248
- Connect power flushing equipment so the flushing fluid flows in the direction of normal fluid flow.
- Flush oil cooler/lines until discharge fluid is clean.
Scheme 249
- Disconnect the negative battery cable.
- Drain the coolant into a container. (See ENGINE COOLANT REPLACEMENT .)
- Drain the ATF into a container. (See «AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT»(ref-178052-S24716482602005061000000) .)
