Note: GM does not provide timing chain timing marks, or information to perform timing chain service without the special tools shown in this procedure. Tools Required: – - J 36800 Camshaft Sprocket Timing Alignment Pin J 39579 Camshaft Sprocket Wrench Important: ^ ^ Before remove the timing chain, read the entire procedure. The timing chain on the engine is not to be replaced with the timing chain from any other model year. The timing sprockets are different on the engine and the shape of the links matches the sprockets. Engine damage may result if the wrong timing chain is used. The timing chain and the crankshaft sprocket must be marked in order to insure reassembly with the same side facing out at the time of reassembly. ^ Caution: Refer to Battery Disconnect Caution in Service Precautions. 1. Disconnect the negative battery cable. 2. Remove the engine front cover. Refer to Engine Front Cover Replacement. 3. Rotate the crankshaft clockwise (as viewed from the front of the engine, normal rotation) until the camshaft sprocket timing dowel pin holes line up with the holes in the timing chain housing. 4. The crankshaft sprocket keyway should point upwards and line up with the centerline of the cylinder bores. This is the Timed position. 5. Remove the timing chain guides. 6. Raise and support the vehicle. Refer to Vehicle Lifting. 7. Ensure that all of the slack in the timing chain is above the tensioner assembly. 8. Remove the timing chain tensioner. 9. The timing chain must be disengaged from any wear grooves in the tensioner shoe in order to remove the shoe. Slide a screwdriver blade under the timing chain while pulling the shoe outward. Notice: Do NOT attempt to pry the sprocket off the camshaft or damage to the sprocket or chain housing could occur. 10. If difficulty is encountered in removing the timing chain tensioner shoe, use the following procedure in order to remove the intake camshaft sprocket: 10.1. 10.2. 10.3. 10.4. Lower the vehicle. Hold the intake camshaft sprocket with the J 39579 and remove the sprocket bolt and washer. Remove the washer from the bolt and rethread the bolt back into the camshaft by hand (the bolt provides a surface to push against). Remove the intake camshaft sprocket. Use a three-jaw puller in the three relief holes in the sprocket.

ENGINE WILL NOT START NVIS/NATS SYSTEM DESCRIPTION/KEY REGISTRATION This version of NTB03-031 amends the Applied Vehicles. Please discard all paper copies of the earlier versions. APPLIED VEHICLES: 2005 and later Altima (L31), Pathfinder (R51), Frontier (D40), Xterra (N50), 350Z (Z33) 2004 and later Maxima (A34), Quest (V42), Armada (TA60), Titan (A60), Murano (Z50) 2004 350Z (Z33) built after the following:NOTE: ^ For 2003 Murano, and 2003-2004 350Z built before the above Date and VIN’s, see NTB02-071 ^ This bulletin does NOT cover 2002-2004 Altima. SERVICE INFORMATION ^ This bulletin covers the latest version of the Nissan Vehicle Immobilizer System/Nissan Anti-Theft System (NVIS/NATS). This system, referred to as “NATS”, is standard equipment on the Applied Vehicles listed above. ^ This version of NATS uses advanced anti-theft functions which are “password protected”. This helps prevent “unauthorized access” into the NATS registration procedure. ^ To obtain the password from ASIST, first use CONSULT-II to get the “BCM-specific” 5-digit number (PIN) code from the vehicle. ^ Unlike earlier NATS systems, this NATS system DOES NOT need to be Re-Initialized if the Electronic Control Unit (ECM) is replaced. NOTE: The ECM and Body Control Module (BCM) do work together, but the BCM in this system controls the information necessary to “tell” the ECM to start the vehicle. IMPORTANT: The NATS Procedure in this bulletin is for the Applied Vehicles only. Do not use this procedure on other NATS-equipped vehicles.

1. Remove the engine front cover; refer to the procedure in this section. 2. Remove the (A) crankshaft sensor ring from the (B)crankshaft (6303). 3. On WEP engines, use the (A) Camshaft Positioning Tool to position the (B) camshaft. 4. on REP engines, rotate the crankshaft until both camshaft keyways are 90° from the cam cover surface. On REP and WEP engines, make sure the copper links line up with the dots on the camshaft sprockets. 5. On REP equipped engines, install the (A) Cam Positioning Tool and the Camshaft Positioning Tool Adapters on the (B) camshaft. 6. On WEP engines, install the (A) Camshaft Holding Tool on the (B) camshaft. 7. Remove the (A) LH timing chain tensioner bolts and the (B) LH timing chain tensioner. 8. Remove the (A) RH timing chain tensioner bolts and the (B) RH timing chain tensioner. 9. Remove the LH and RH timing chain tensioner guides from the dowel pins. 10. CAUTION: At no time, when the timing chains are removed and the cylinder heads are installed may the crankshaft or camshaft be rotated. Severe piston and valve damage will occur. Remove the RH and LH timing chains and crankshaft sprockets. 1. Lift RH timing chain off of the camshaft sprocket and slide the timing chain and crankshaft sprocket off of the crankshaft. 2. Lift the LH timing chain off the camshaft sprocket and slide the timing chain and the crankshaft sprocket off of the crankshaft. 11. On REP engines, remove the chain guides. 1. Remove the LH timing chain guide bolts. 2. Remove the LH timing chain guide. 3. Remove the RH timing chain guide bolts. 4. Remove the RH timing chain guide.
