Classification: Reference: AT14-016d Date: NTB15-013d April 24, 2017 NISSAN; PROCEDURE TO CLEAN CVT TRANSMISSION FLUID COOLERS This bulletin has been amended. The APPLIED VEHICLES section has been revised. No other changes have been made. Please discard previous versions of this bulletin. APPLIED VEHICLES: 2013-2017 Pathfinder (R52) – V6 only 2013-2015 Altima (L33) – 4 cylinder and V6 2016-2017 Altima (L33) – V6 only 2015-2017 Murano (Z52) – V6 only 2015-2017 Quest (E52) 2016-2017 Maxima (A36) 2014-2017 Rogue (T32) 2015-2017 Juke (F15) APPLIED TRANSMISSION: CVT IMPORTANT: Metal debris and friction material may become trapped in the radiator, cooling hoses, bypass valve or external CVT fluid cooler. This debris can contaminate the newly serviced transmission, control valve or torque converter. In severe cases this debris can block or restrict flow and may cause damage to the newly serviced CVT. SERVICE INFORMATION When a CVT, control valve, or torque converter replacement is necessary for one of the Applied Vehicles, the CVT transmission fluid coolers (radiator based fluid cooler and external auxiliary cooler if present) must be flushed. NOTE: Refer to the Workflow on page 2 to determine the correct Service Procedure for the specific vehicle being serviced. 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. 1/8 SERVICE PROCEDURE Workflow: Replacement required (1) No Yes Pathfinder Bulletin does not apply Model Perform: Flushing Radiator based CVT Transmission Fluid Cooler Perform: Flushing External CVT Transmission Auxiliary Fluid Cooler Other than Pathfinder Perform only: Flushing Radiator based CVT Transmission Fluid Cooler Procedure end (1) Replacement of CVT, control valve, or torque converter. Flushing Radiator based CVT Transmission Fluid Cooler IMPORTANT: the CVT fluid cooler hoses will be flushed in both directions in the following procedure. 1. Place the vehicle on a lift. 2. Is the vehicle a Pathfinder? Yes: Remove the left front wheel and then partially remove the left front fender protector to gain access to the CVT fluid cooler and then proceed to step 3. Refer to the Electronic Service Manual (ESM), section EXT – Exterior for information. No: Proceed to step 5. 2/8 NTB15-013d 3. Place an oil drain pan under the CVT fluid cooler. 4. Unbolt and disconnect the external CVT fluid cooler bypass valve from the external CVT fluid cooler (Figure 1). Two (10 mm head) bolts attach bypass valve to the fluid cooler. The other bolt is on the opposite side of bypass valve. Figure 1 5. Place an oil drain pan under the CVT warmer. 6. Disconnect the CVT fluid cooler inlet and outlet rubber hoses from the CVT Fluid warmer (Figure 2) and discard spring clamps. NOTE: If rubber material from a cooler hose remains on the steel tube or fitting, replace the rubber hose and clean steel tube. 7. Allow any transmission fluid that remains in the CVT fluid cooler hoses to drain into the oil drain pan. All vehicles, other than Pathfinder, have both CVT fluid warmer hoses routed directly to the CVT fluid cooler in the radiator. CVT fluid warmer to CVT fluid cooler hose. (Pathfinder only) All other applied vehicles are routed from CVT fluid warmer directly to “radiator based” fluid cooler CVT fluid warmer CVT fluid warmer to radiator hose (All applied vehicles) To radiator CVT fluid cooler CVT fluid cooler (Pathfinder only) To radiator CVT fluid cooler Figure 2 3/8 NTB15-013d NOTE: The two hoses that have been removed from the CVT fluid warmer will be flushed first in one direction and then the other. CAUTION: Wear safety glasses and rubber gloves when spraying the Transmission Cooler Cleaner. Spray Cooler Cleaner only in areas with adequate ventilation. Avoid contact with eyes and skin. Do not breathe vapors or mist from spray. 8. Insert the “extension adapter hose”, from a can of Transmission Cooler Cleaner (Nissan P/N 999MP-AM006P), into one or the other of the disconnected CVT fluid cooler hoses (Figure 3). Fluid outlet Fluid inlet CVT fluid cooler bypass valve (Pathfinder only) Figure 3 9. Flush CVT fluid cooler (radiator based) and hoses: a. Hold the hose and can as high as possible. For Pathfinder, block the CVT fluid cooler bypass valve fluid passage (Figure 3) with thumb. Place thumb over this fluid passage (Pathfinder only) b. Spray Transmission Cooler Cleaner, in a continuous stream, into the CVT fluid cooler inlet hose. c. Spray fluid until it flows out of the other hose for 5 seconds. 10. Slide a piece of 5/8 inch hose (16 mm) over the end of the CVT fluid cooler hose (Figure 4) that was used as the flush inlet. 5/8 inch hose 11. Insert the tip of an air gun into the end of 5/8 inch (16 mm) hose (Figure 4). For Pathfinder block the CVT fluid cooler bypass valve fluid passage (Figure 3) with thumb. 12. Blow compressed air, regulated to 5-9 kg/cm2 (70 – 130 PSI), through the CVT fluid cooler hose for 10 seconds to force out any remaining fluid. Figure 4 13. Repeat steps 8 through 12 one additional time and then proceed to step 14. 4/8 NTB15-013d 14. Now reverse the direction that the hoses are being flushed (Figure 3) and repeat steps 8 through 12 twice. When complete proceed to step 15. 15. Reassemble the CVT fluid cooler hoses to the CVT warmer with new spring clamps from PARTS INFORMATION in the reverse order of disassembly. Refer to the Electronic Service Manual (ESM), section TM – Transaxle & Transmission for correct hose assembly and alignment. 16. If the vehicle is a Pathfinder proceed to Flushing External auxiliary oil cooler. Flushing External CVT Transmission Auxiliary Fluid Cooler (Pathfinder only) 1. Remove the CVT fluid cooler (auxiliary fluid cooler) from vehicle. CVT fluid cooler Refer to the Electronic Service Manual (ESM), section TM – Transaxle & Transmission for information. Figure 5 2. Remove O-rings from auxiliary fluid cooler and discard. Outlet 3. Install a 4 inch long hose with an inside diameter of 5/8 inch (16 mm) onto the inlet side of the auxiliary fluid cooler. 4. Install a 6 inch long hose with inside diameter of 5/8 inch (16 mm) onto outlet of the auxiliary fluid cooler and place the opposite end into a suitable container to catch used fluid. Inlet Figure 6 5/8 NTB15-013d Inlet 5. Insert the “extension adapter hose” from a can of Transmission Cooler Cleaner (Nissan P/N 999MP-AM006P) into the auxiliary fluid cooler inlet (Figure 7). 6. Spray one full can of Transmission Cooler Cleaner through inlet of auxiliary fluid cooler letting cleaner drain through the outlet and into a container. 7. Allow the remaining fluid in the auxiliary fluid cooler to drain out. Figure 7 8. Insert the tip of an air gun into the end of the auxiliary fluid cooler inlet (Figure 8). 9. Wrap a shop rag around the air gun tip and end of the cooler inlet (Figure 8) to reduce blowback. 10. Blow compressed air, regulated to 5-9 kg/cm2 (70 – 130 PSI), through the inlet side of the auxiliary fluid cooler for 10 seconds to force out any remaining fluid. Figure 8 Suction gun 11. While holding the hoses securely to the auxiliary fluid cooler (Figure 9), flush 2 full quarts of NS-3 (or equivalent) with a 1 pint suction gun. Inlet Flush from the inlet side of the auxiliary fluid cooler through to the outlet (Figure 9). 12. Allow the remaining fluid in the auxiliary fluid cooler to drain out. Figure 9 6/8 NTB15-013d 13. To complete the flush, insert the tip of an air gun again into the end of the auxiliary fluid cooler inlet (Figure 8). 14. Wrap a shop rag around the air gun tip and end of the cooler inlet (Figure 8). 15. Blow compressed air, regulated to 5-9 kg/cm2 (70 – 130 PSI), through the inlet of the auxiliary fluid cooler for 10 seconds to force out any remaining NS-3 fluid. 16. Reassemble the auxiliary fluid cooler and CVT fluid cooler bypass valve in the reverse order of disassembly with new O-rings from PARTS INFORMATION. Refer to the Electronic Service Manual (ESM), section TM – Transaxle & Transmission for correct hose assembly and alignment 7/8 NTB15-013d PARTS INFORMATION DESCRIPTION Hose spring clamp External CVT Cooler O-Rings (Pathfinder only) Transmission Cooler Cleaner NS-3 CVT Fluid PART # 16439-7S01D 22180-9NB0A 999MP-AM006P (1) 999MP-NS300P (1) (2) QUANTITY 2 2 As needed As needed (1) Order this item through the Nissan Maintenance Advantage program: Phone: 877-NISNMA1 (877-647-6621).
