A/T Fluid Cooler Cleaning
Whenever an A/T is repaired, overhauled, or replaced, the A/T fluid cooler mounted in the radiator must be inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can contaminate the newly serviced A/T or, in
severe cases, can block or restrict the flow of A/T fluid. In either case, malfunction of the newly serviced A/T may result.
Debris, if present, may build up as A/T fluid enters the cooler inlet. It will be necessary to back flush the cooler through the cooler outlet in order to
flush out any built up debris.
A/T FLUID COOLER CLEANING PROCEDURE
1. Position a drain pan under the A/T inlet and outlet fluid cooler tube to cooler hose connection.
2. Put a different color matching mark on each cooler tube to cooler hose connection to aid in assembly.
CAUTION:
Use paint to make the matching mark. Do not damage the tubes or hose.
3. Disconnect the fluid cooler inlet and outlet rubber hoses from the steel cooler tubes.
NOTE:
Replace the cooler hoses if rubber material from the hose remains on the tube fitting.
4. Drain any A/T fluid from the cooler hose.
5. Insert the extension adapter hose of a can of Transmission Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler outlet hose.
CAUTION:
-
Wear safety glasses and rubber gloves when spraying the Transmission Cooler Cleaner.
-
Spray cooler cleaner only with adequate ventilation.
-
Avoid contact with eyes and skin.
-
Do not breath vapors or spray mist.
6. Hold the hose and can as high as possible and spray Transmission Cooler Cleaner in a continuous stream into the cooler outlet hose until fluid
flows out of the cooler inlet hose for 5 seconds.
