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.

DESCRIPTION Some vehicles may experience a body vibration when driving approximately 55mph. This symptom is due to the characteristics of the No. 3 & No. 4 engine mounts. Modified No. 3 & No. 4 engine mounts have been established for service only. Customers having this concern should have their vehicle repaired using the following repair procedure. REPAIR PROCEDURE IMPORTANT NOTE: • This repair should only be performed if all tires and rims are confirmed to be in balance and all suspension components are in proper working condition. • Notify customers that use of the modified mounts will reduce vibration at cruising speed but may increase vibration at idle. NOTE: Because idle vibration may increase, it is highly recommended to continue using mass production mounts for all other service concerns. 1. Verify concern. 2. Replace the No. 3 & 4 engine mounts with service parts according to the appropriate Workshop Manual section 01-10 ENGINE REMOVAL/INSTALLATION. 3. Center the new engine mounts as outlined in ENGINE MOUNT CENTERING PROCEDURE. 4. Verify repair. ENGINE MOUNT CENTERING PROCEDURE No. 1, No. 3 and No. 4 Engine Mount Adjustment 1. Warm up the engine. 2. Raise and support vehicle on a hoist. 3. Remove engine under cover. 4. Lower the vehicle until the front tires lightly touch the ground. 5. Secure the engine and transaxle using an engine jack and attachment as instructed in No.3 Engine Mount And No.4 Engine Mount Rubber Installation Note in appropriate Workshop Manual, section 01-10 MECHANICAL. 6. Remove two bolts from No. 3 engine mount bracket. REMOVE THE BOLTS 7. Lift engine using jack until No.3 engine mount is lifted slightly from vehicle body. NOTE: • Do not raise engine too much or A/C pipe damage may occur. 8. Move the engine mount rubber or engine until installation hole on the vehicle body aligns with hole in the engine mount bracket. ENGINE MOUNT BRACKET 1532c SHOWN BEFORE ALIGNING THE HOLES SHOWN AFTER ALIGNING THE HOLES 9. Lower the jack and tighten bolts on No. 3 engine mount bracket. Tightening torque: 55.0-77.3 ft-lbf (74.5-04.9 N.m) NOTE: 10. With engine supported as described in STEP 5, remove four (4) nuts and two (2) bolts from No. 4 engine mount top plate. Remove top plate. NOTE: 11. Lift engine again using jack until No.4 engine mount is lifted slightly from vehicle body. NOTE: 12. With top plate of No. 4 engine mount removed, move engine mount bottom plate or engine until all four (4) installation studs on the vehicle align with the engine mount holes. • Do not allow the engine mount bracket to be misaligned. • To access the mount, remove battery box. • Do not raise engine too much or A/C pipe damage may occur. ALIGN THE 4 STUDS IN THE PLATE HOLES 13. Place top plate back on and tighten No. 4 engine mount bracket nuts and bolts to torque indicated. Tightening torque: A.32.5-45.0 ft-lbf (44.0-61.0 N.m) B.61.1-86.7 in-lbf (6.9-9.8 N.m) TIGHTEN BOLTS IN SEQUENCE SHOWN 1532e 14.

Introduction IMPORTANT It is mandatory that the VVT-i gear actuator bolts, actuator center section alignment, and actuator body be inspected BEFORE performing this TSB. If no concerns are noted with these parts, this TSB does NOT apply. Some 2005 – 2009 model year vehicles with 2GR-FE engines may exhibit a ticking/clicking type noise from the cylinder head cover area which may be accompanied by a MIL “ON” and one or more VVT-i related Diagnostic Trouble Codes (DTCs). Please use the following repair procedure to address customer concerns. Inspection Procedure 1. Start the engine and listen for any ticking/clicking type noises coming from the VVT-i gear area of the engine. NOTE This condition may or may not be accompanied by one or more of the following DTCs stored in the Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM): • P0014: Camshaft Position “B” – Timing Advanced or System Performance (Bank 1) • P0015: Camshaft Position “B” Timing Over Retarded (Bank 1) • P0017: Crankshaft Position Camshaft Position Correlation (Bank 1 Sensor B) • P0018: Crankshaft Position Camshaft Position Correlation (Bank 2 Sensor A) • P0024: Camshaft Position “B” – Timing Over-Advanced or System Performance (Bank 2) • P0025: Camshaft Position “B” – Timing Over-Retarded (Bank 2) 2. Remove the cylinder head cover and inspect the exhaust VVT-i gear assembly on the affected cylinder bank. NOTE If NO concerns are found with the VVT-i gear actuator bolts, the actuator center section alignment, or actuator body, this TSB does NOT apply. Refer to Repair Manual procedures for further diagnosis. Repair Procedure 1. If any concerns are noted with the exhaust VVT-i gear bolts or actuator follow the four steps below: A. Replace the camshaft housing sub-assembly, exhaust camshaft, and exhaust VVT-i gear assembly on the affected bank. B. Inspect the intake VVT-i gear assembly and bolts on the affected bank. Replace the intake VVT-i gear assembly if necessary. C. Inspect the opposite bank exhaust VVT-i gear actuator and bolts. If any concerns are noted replace the opposite bank camshaft housing sub-assembly, exhaust camshaft, and exhaust VVT-i gear assembly. D. Inspect the opposite bank intake gear actuator assembly and bolts. Replace the intake VVT-i gear assembly if necessary. For complete disassembly procedures refer to the Technical Information System (TIS), applicable model and model year Repair Manual: • 2005 Avalon: Engine/Hybrid System – Engine Mechanical – “Engine Mechanical: Camshaft (LH Bank) / (RH Bank) (2GR-FE): Replacement” • 2006 / 2007 / 2008 / 2009 Avalon: Engine/Hybrid System – Engine Mechanical – “2GR-FE Engine Mechanical: Engine Unit: Disassembly” • 2007 / 2008 / 2009 Camry: Engine/Hybrid System – Engine Mechanical – “2GR-FE Engine Mechanical: Engine Unit: Disassembly” • 2008 / 2009 Highlander: Engine/Hybrid System – Engine Mechanical – “2GR-FE Engine Mechanical: Engine Unit: Disassembly” • 2006 / 2007 / 2008 / 2009 RAV4: Engine/Hybrid System – Engine Mechanical – “2GR-FE Engine Mechanical: Engine Unit: Disassembly”
