2013 PATHFINDER; CVT FLUID LEAK AT COOLER HOSE
APPLIED VEHICLE: 2013 Pathfinder (R52)
IF YOU CONFIRM:
CVT fluid is leaking from the transmission to radiator cooler hose:
•
At the connection of the hose to line fitting on the radiator.
•
Or the hose has become detached while the vehicle was driving.
NOTE: If CVT fluid is leaking from any other location, this bulletin does not apply.
Refer to the Electronic Service Manual (ESM) for further Diagnosis.
ACTION:
If CVT fluid is leaking, please refer to the flow chart on page 3 to determine the correct
ACTION.
IMPORTANT: The purpose of "ACTION" (above) is to give you a quick idea of the work
you will be performing. You MUST closely follow the entire Service Procedure as it contains
information that is essential to successfully completing this repair.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

1. If the “CVT to radiator” transmission cooler hose was detached from the radiator while
the vehicle was being driven:
•
•
Replace the CVT and then proceed to step 2.
If the “CVT to radiator” transmission cooler hose was not detached while driving,
do not replace the CVT and proceed to step 2.
NOTE: Refer to:
• The appropriate section of the ESM for the procedure to remove and reinstall the
CVT.
• Additional services for CVT replacement. “D: TRANSMISSION & DRIVELINE /
TM-Transaxle & Transmission / CVT: RE0F10E / BASIC INSPECTION /
ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY”.
2. Replace the radiator.
NOTE: Refer to the appropriate section
of the ESM for the procedure to remove
and reinstall the radiator.
3. Re-attach the engine coolant hoses to
the new radiator, and only the “auxiliary
cooler to radiator hose” (CVT Fluid
Cooler Hose C).
•
Leave the “transmission to radiator
cooler hose” loose at this time (CVT
Fluid Cooler Hose A/B Assembly,
Figure 1).
4. On the CVT, slide the “transmission to
radiator cooler hose” spring clamp back
onto the hose, away from the fitting, and
then remove the hose from the fitting
(Figure 2).
•
Disconnect the two hose support
clips to radiator fan shroud.
•
Discard this hose and related
clamps. They will be replaced with
the parts from the PARTS
INFORMATION table.
Leave this hose loose.
It will be replaced.

5. Slide two clamps onto the radiator side (Figure 3), and then one spring clamp onto the
CVT side (Figure 4) cooler line fittings.
•
On the radiator side a double wire clamp is installed first, followed by a spring clamp.

6. Clean the outer surfaces of both the radiator and the CVT fittings with an alcohol wipe
from the Squeak and Rattle Kit (or Nissan brake cleaner 999MP-A3042P).
7. Install the new hose from the PARTS INFORMATION table onto the CVT and radiator
fittings and re-attach the two hose support clips to radiator fan shroud.
NOTE: Refer to “D: TRANSMISSION & DRIVELINE / TM-Transaxle & Transmission /
CVT: RE0F10E / REMOVAL AND INSTALLATION / CVT FLUID COOLER SYSTEM”
for correct positioning of cooler hoses onto fittings.
8. Position the spring clamps at the CVT and radiator cooler (Figures 5 and 6) as close to
the fitting bulge as possible, and then release them.
NOTE: Confirm that the clamps are not on top of the fitting bulge or on an angle.
