APPLIED VEHICLES: 2004-2008 Maxima (A34) 2004-2006 Altima (L31) with VQ35 engine ONLY 2004-2009 Quest (V42) IF YOU CONFIRM: There is a high frequency buzzing / whining noise coming from the secondary timing chain system. • The noise should increase in frequency with engine speed (RPM). • If the noise does not increase with engine speed, the timing chain system may not be the cause. Refer to the appropriate section of the Electronic Service Manual (ESM) for further diagnosis. ACTION: 1. Replace both secondary timing chains and both secondary timing chain tensioner “shoes” with the ones from the PARTS INFORMATION section of this bulletin (on Page 2). 2. Change the engine oil and filter. 3. For repair procedure, refer to the SERVICE PROCEDURE section of this bulletin (starting on Page 3). SERVICE PROCEDURE Write down all radio station presets. 2. Disconnect both battery cables, negative cable first. 3. Remove the secondary timing chains. Refer to the Electronic Service Manual (ESM) if needed. NOTE: It is not necessary to remove the valve covers or intake collector. • Before removing the crankshaft pulley, set it to 0° Top Dead Center (TDC). • Use Tool J-50288 to secure the flywheel / flex plate when removing the crankshaft pulley and camshaft sprockets (no picture shown). NOTE: The camshaft sprockets’ bolts will be removed and installed while being held by all three (3) timing chains. • If the crankshaft is determined to be 360° off from 0° TDC on #1 cylinder compression stroke after removing the front timing chain case (front cover), put the crankshaft pulley back on, and then rotate the crankshaft 360° (when camshaft and crankshaft sprocket mating marks are aligned). • Use the chain tensioner pins (pin) from Tool Kit J-50246 to hold all 4. Remove the chain tensioner plungers. three (3) Secondary Timing Chain Tensioner 1 shows a pin by evenly prying Figure Shoes (shoe) used on B2 with a couple pocket screwdrivers or tensioner. suitable tool where shown in Figure 1. NOTE: The primary timing chain will be reused. If the original markings are not legible, it is recommended to NOTE: Leave the pins from Tool mark this chain tensioner sprockets J-50246 in eachto all three until the with “white-out” or suitable timing chains are installed. marking before removing. 4. Remove the Secondary Timing Chain Tensioner Shoes (shoe) by evenly prying with a couple pocket to the tensioners 5.

1. Drain coolant by removing cylinder block drain plug and opening radiator drain cock. Drain engine oil. Remove oil pan. See OIL PAN . Remove power steering pump and position it to side. Remove idler pulley and bracket as well. Set No. 1 piston at TDC on its compression stroke. CAUTION: Be careful not to tear or damage cylinder head gasket. NOTE: Engine may need to be lowered to provide clearance for chain tensioner housing of timing cover to clear frame. Engine height may need to be adjusted when removing cover. 2. Remove crankshaft pulley. Remove oil separator. Remove front cover. Remove following parts; Lower timing chain tensioner (push piston in and insert a suitable pin into hole). Chain tension arm. Lower timing chain guide. 3. Remove upper timing chain. See REMOVAL (ALTIMA) – UPPER TIMING CHAIN . Wipe off links of timing chain next to timing marks on sprockets. Apply paint marks to lower timing chain, matching them with mating marks on crankshaft sprocket and idler sprocket. See Fig. 17 . Remove lower timing chain and sprocket.

SERVICE INFORMATION A revised service procedure for the engine front cover/timing chain has been adopted for the GA16DE. It is no longer recommended to remove the cylinder head when removing the timing chain/front cover(s). Utilize the following steps when servicing the front cover, timing chain, guides or tensioner(s) PARTS INFORMATION Caution ^ After removing the timing chain, do not turn the crankshaft and camshaft separately or the valves will strike the piston heads. ^ When installing chain tensioners or other sliding parts, lubricate contacting surfaces with new engine oil. ^ Apply new engine oil to bolt threads and seat surfaces when installing the camshaft sprockets and the crankshaft pulley. ^ Do not spill engine coolant on the drive belts. ^ Please refer to the Service Manual for the correct tightening torque. Removal 1. Set # 1 piston at TDC on its compression stroke. 2. Remove the spark plug wires. 3. 4. Remove the rocker cover (see Figure 1). Remove the coolant reservoir tank with bracket and reposition it for clearance. 5. Support the engine with a suitable jack. 6. Remove cylinder head front mounting bracket. 7. Remove engine front mounting, then the engine front mounting bracket. 8. Remove cylinder head front cover. 9. Remove the upper chain tensioner (see Figure 2). 10. Wipe off the links of the upper timing chain next to the timing marks on the sprockets. Put paint marks on the timing chain, matching them with the timing marks on the cam sprockets and idler sprocket (see Figure 3) 11. Remove the four (4) front cover to cylinder head bolts. 12. Remove side and lower engine compartment splash covers. 13. Remove the accessory drive belts. 14. Remove the crankshaft pulley. 15. Drain coolant by removing the cylinder block drain plug and opening the radiator drain cock (Refer to MA section of the Service Manual). 16. Drain engine oil. 17. Remove intake manifold support of engine front side. 18. Remove power steering pump, pump bracket and tension rod. Position pump aside for clearance.

CAUTION: – Do not bend or twist timing belt. – After removing timing belt, do not turn crankshaft and camshaft separately because valves will strike piston heads. – Make sure that timing belt, camshaft sprocket, crankshaft sprocket and belt tensioner are clean and free from oil and water. – Installation should be carried out when engine is cold. Removal 1. Jack up the vehicle front and support with safety stand. 2. Remove engine under cover. 3. Remove front RH wheel and engine side cover. 4. Drain engine coolant from radiator. 5. Remove the following belts. – Compressor drive belt – Generator drive belt – Power steering pump drive belt Timing Marks 6. Set No. 1 piston at TDC of its compression stroke. 7. Loosen crankshaft pulley bolt. 8. Remove crankshaft pulley using a suitable puller. 9. 10. 11. 12. 13. Remove radiator upper hose and water inlet hose. Remove compressor drive belt idler bracket. Remove water pump pulley. Remove breather pipe from timing belt front upper cover. Remove timing belt front covers.
