Nissan Rogue Service Manual: CVT fluid cooler system
Cleaning
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
- Position an oil pan under the transaxle's inlet and outlet cooler
hoses.
- Identify the inlet and outlet fluid cooler hoses.
- 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.
- Allow any CVT fluid that remains in the cooler hoses to drain into
the oil pan.
- 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 Transmission Cooler Cleaner only with adequate
ventilation.
- Avoid contact with eyes and skin.
- Never breath vapors or spray mist.
- Hold the hose and can as high as possible and spray Transmission
Cooler Cleaner in a continuous stream into the cooler outlet
hose until CVT fluid flows out of the cooler inlet hose for 5 seconds.
- Insert the tip of an air gun into the end of the cooler outlet
hose.
- Wrap a shop rag around the air gun tip and end of the cooler
outlet hose.
- Blow compressed air regulated to 5 to 9 kg/cm2 (70 to 130 psi)
through the cooler outlet hose for 10 seconds to force out any
remaining CVT fluid.
- Repeat steps 5 through 9 three additional times.
- Position an oil pan under the banjo bolts that connect the CVT
fluid cooler steel lines to the transaxle.
- Remove the banjo bolts.
- Flush each steel line from the cooler side back toward the
transaxle
by spraying Transmission Cooler Cleaner in a continuous stream for 5
seconds.
- Blow compressed air regulated to 5 to 9 kg/cm2 (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.
- Ensure all debris is removed from the steel cooler lines.
- Ensure all debris is removed from the banjo bolts and fittings.
- 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.
- Position an oil pan under the transaxle's inlet and outlet cooler
hoses.
- Clean the exterior and tip of the cooler inlet hose.
- 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 Transmission Cooler Cleaner only with adequate
ventilation.
- Avoid contact with eyes and skin.
- Never breath vapors or spray mist.
- Hold the hose and can as high as possible and spray Transmission
Cooler Cleaner in a continuous stream into the cooler outlet
hose until CVT fluid flows out of the cooler inlet hose for 5 seconds.
- Tie a common white, basket-type coffee filter to the end of the
cooler inlet hose.
- Insert the tip of an air gun into the end of the cooler outlet hose.
- Wrap a shop rag around the air gun tip and end of cooler outlet
hose.
- Blow compressed air regulated to 5 to 9 kg/cm2 (70 to 130 psi)
through the cooler outlet hose to force any remaining CVT fluid
into the coffee filter.
- Remove the coffee filter from the end of the cooler inlet hose.
- Perform “CVT FLUID COOLER INSPECTION PROCEDURE”.
CVT FLUID COOLER INSPECTION PROCEDURE
- Inspect the coffee filter for debris.
- 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.
CVT FLUID COOLER FINAL INSPECTION
After performing all procedures, ensure that all remaining oil is cleaned
from all components.
