OIL COOLER FLUSHINGA6E571419900202
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.
Recommended power-flushing manufacturer
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 & clamps
1. Be sure to inspect the lines (hoses/pipes) for cuts, crimps (pinched), cracks or any other damage before
reusing them. If any problem exists replace it.
Caution
•Always use new clamps when replacing hoses.

4. Remove in the order indicated in the table.
5. Install in the reverse order of removal.
6. Add ATF to the specified level. (See K2–80 AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT.)
7. Connect the negative battery cable.
8. Inspect for oil leakage from the oil pipes and oil hoses.
9. Inspect for coolant from the hoses.
10. Inspect the ATF level and condition. (See K2–78 AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION.)
11. Carry out the line pressure test. (See K2–72 MECHANICAL SYSTEM TEST.)
12. Carry out the road test. (See K2–75 ROAD TEST.)
.
Radiator (In Tank Oil Cooler) Installation Note
1. The automatic transaxle oil cooler flushing must be performed whenever a transaxle is removed for service
because the existing fluid may be contaminated, and to prevent contamination of new fluid.
Note
• The flushing must be performed after installation of the overhauled or replacing transaxle.
2. Follow the instructions in the manufacturer’s publication for flushing operation.

PRECAUTION (BRAKES)A6E691001020201Wheels and Tires Removal/Installation
1. The removal and installation procedures for the wheels and tires are not mentioned in this section. When a
wheel is removed, tighten it to 88—118 N·m {9.0—12.0 kgf·m, 65.0—87.0 ft·lbf}.
Brake Lines Disconnection/Connection
Caution
•Brake fluid will damage painted surfaces. If brake fluid does get on a painted surface, wipe it off
immediately.
1. Tighten the brake pipe flare nut using the SST (49 0259 770B). Be sure to modify the brake pipe flare nut
tightening torque to allow for use of a torque wrench-SST combination.
•If any brake line has been disconnected anytime during the procedure, add brake fluid, bleed the brakes,
and inspect for leakage after the procedure has been completed.
Connectors Disconnection
1. Disconnect the negative battery cable before doing any work that requires handling of connectors. Reconnect
the negative battery cable only after the work is completed.
ABS, ABS/TCS, or DSC Components Operations
1. Make sure that there are no DTCs in the ABS, ABS/TCS, or DSC memory after working on ABS, ABS/TCS or
DSC components.
•If there are any DTCs in the memory, clear them.
