CVT FLUID COOLER SYSTEM
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.

If one or more pieces of debris are found that are over 1 mm
(0.040 in) in size and/or peeled clutch facing material is found in
the coffee filter, the fluid cooler is not serviceable. The radiator/
fluid cooler must be replaced and the inspection procedure is
ended.

INSPECTION
1.
Inspect the amount of engine oil. Replenish the engine oil if necessary.
2.
Drive for about 10 minutes to warm up the vehicle so that the
CVT fluid temperature is 50 to 80
°
C (122 to 176
°
F). Inspect the
amount of CVT fluid. Replenish if necessary.
3.
Securely engage parking brake so that the tires do not turn.
4.
Install a tachometer where it can be seen by driver during test.
NOTE:
It is good practice to mark the point of specified engine rpm on
indicator.
5.
Start engine, apply foot brake, and move selector lever to “D”
position.
6.
Gradually press down accelerator pedal while holding down the
foot brake.
7.
Quickly read off the stall speed, and then quickly remove your
foot from accelerator pedal.
CAUTION:
Never hold down accelerator pedal for more than 5 seconds
during this test.
8.
Move selector lever to “N” position.
9.
Cool down the CVT fluid.
CAUTION:
Run the engine at idle for at least 1 minute.
10. Repeat steps 6 through 9 with selector lever in “R” position.
