CVT FLUID COOLER SYSTEM
Cleaning
INFOID:0000000007576456
Whenever an automatic transaxle is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the
radiator must be inspected and cleaned.
Metal debris and friction material, if present, can be trapped or be deposited in the CVT fluid cooler. This
debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid.
In either case, malfunction of the newly serviced CVT may occur.
Debris, if present, may deposit as CVT 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.
CVT FLUID COOLER CLEANING PROCEDURE
1.
Position an oil pan under the transaxle's inlet and outlet cooler hoses.
2.
Identify the inlet and outlet fluid cooler hoses.
3.
Disconnect the fluid cooler inlet and outlet rubber hoses from the
steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.
4.
Allow any CVT fluid that remains in the cooler hoses to drain into
the oil pan.
5.
Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.
CAUTION:
• Wear safety glasses and rubber gloves when spraying the
Transmission Cooler Cleaner.
• Spray Transmission Cooler Cleaner only with adequate
ventilation.
• Avoid contact with eyes and skin.
• Never breath vapors or spray mist.
6.
Hold the hose and can as high as possible and spray Transmis-
sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until CVT fluid flows out of the cooler inlet hose for 5 seconds.
7.
Insert the tip of an air gun into the end of the cooler outlet hose.
8.
Wrap a shop rag around the air gun tip and end of the cooler
outlet hose.
9.
Blow compressed air regulated to 5 to 9 kg/cm
2
(70 to 130 psi)
through the cooler outlet hose for 10 seconds to force out any
remaining CVT fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connect the CVT
fluid cooler steel lines to the transaxle.
12. Remove the banjo bolts.
13. Flush each steel line from the cooler side back toward the tran-
saxle by spraying Transmission Cooler Cleaner in a continuous stream for 5 seconds.
14. Blow compressed air regulated to 5 to 9 kg/cm
2
(70 to 130 psi) through each steel line from the cooler
side back toward the transaxle for 10 seconds to force out any remaining CVT fluid.
15. Ensure all debris is removed from the steel cooler lines.
16. Ensure all debris is removed from the banjo bolts and fittings.

17. Perform “CVT FLUID COOLER DIAGNOSIS PROCEDURE”.
CVT FLUID COOLER DIAGNOSIS PROCEDURE
NOTE:
Insufficient cleaning of the cooler inlet hose exterior may lead to inaccurate debris identification.
1.
Position an oil pan under the transaxle's inlet and outlet cooler hoses.
2.
Clean the exterior and tip of the cooler inlet hose.
3.
Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.
CAUTION:
• Wear safety glasses and rubber gloves when spraying the
Transmission Cooler Cleaner.
• Spray Transmission Cooler Cleaner only with adequate
ventilation.
• Avoid contact with eyes and skin.
• Never breath vapors or spray mist.
4.
Hold the hose and can as high as possible and spray Transmis-
sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until CVT fluid flows out of the cooler inlet hose for 5 seconds.
5.
Tie a common white, basket-type coffee filter to the end of the
cooler inlet hose.
6.
Insert the tip of an air gun into the end of the cooler outlet hose.
7.
Wrap a shop rag around the air gun tip and end of cooler outlet
hose.
8.
Blow compressed air regulated to 5 to 9 kg/cm
2
(70 to 130 psi)
through the cooler outlet hose to force any remaining CVT fluid
into the coffee filter.
9.
Remove the coffee filter from the end of the cooler inlet hose.
10. Perform “CVT FLUID COOLER INSPECTION PROCEDURE”.
CVT FLUID COOLER INSPECTION PROCEDURE
1.
Inspect the coffee filter for debris.
a.
If small metal debris less than 1 mm (0.040 in) in size or metal
powder is found in the coffee filter, this is normal. If normal
debris is found, the CVT fluid cooler/radiator can be reused and
the procedure is ended.

Move the selector lever and check for excessive effort, sticking, noise or rattle.
4.
Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check that the actual position of the selector lever matches the position shown by the shift
position indicator and the manual lever on the transaxle.
5.
The method of operating the selector lever to individual posi-
tions correctly should be as shown.
6.
When selector button is pressed in “P”, “R” or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.

Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
