This data collection is applicable to all vehicle with engines with sales codes: ERG, ERC, EH3 and ERF. To assist with monitoring and quality improvement of the 3.6L engine, every time a vehicle comes for any of the first 3 oil changes, please use wiTECH to record the total engine idle time and the total engine runtime. 1. Prior to perform the oil change connect wiTECH diagnostic tool. 2. Navigate to the topology screen on the action item section. 3. Once the topology screen loads, disconnect wiTECH and continue with oil change.

roller-finger followers (rocker arms) separately, as these are included in the camshaft parts kit.

Technician's observations can refer to spongy or stuck hydraulic lash adjusters. Exhaust lash adjusters found with a "spongy" condition (compressible plunger) leading to the assumption of being defective/malfunctioning. EXHAUST lash adjusters are designed to be COMPRESSIBLE by hand. Intake lash adjusters found with a stiff or stuck condition (non-compressible plunger) leading to the assumption of being defective/malfunctioning. INTAKE lash adjusters are designed to be NON COMPRESSIBLE by hand. Do Not Replace EXHAUST lash adjusters when the following condition is present: should be compressible, but they will exert a reactionary spring force during compression and return to full expansion without a compression force. Do Not Replace INTAKE lash adjusters when the following condition is present: should feel very firm and difficult to compress. Once the correct functioning of the intake and exhaust lash adjusters is validated with the procedure above, refer to the Service Manual "HYDRAULIC LIFTER(S) NOISE DIAGNOSIS" procedure. After the corresponding service procedures from the Service Manual involving the Lash Adjusters have been conducted, refer to the detailed instructions in the Service Manual to diagnose and/or service any other component.

Lamp (MIL) illumination and the vehicle may exhibit/set one or more of the following Diagnostic Trouble Codes (DTCs): P0301 - Cylinder 1 Misfire. P0302 - Cylinder 2 Misfire. P0303 - Cylinder 3 Misfire. P0304 - Cylinder 4 Misfire. P0305 - Cylinder 5 Misfire. P0306 - Cylinder 6 Misfire. Customers may comment on one or more of the following: Rough idle. Valvetrain noise. "

Refer to SOL # S2509000004. It is also important to confirm that the vehicle being repaired has the latest calibration/software update for oil pump operation mode (high pressure mode) during engine start up. RU, VF, WL & WD vehicles already include the latest oil pump mode in all 25MY and beyond. 24MY service releases are also available. JL & JT were updated as a running change in 24MY and beyond (08/15/24 & 08/19/24 respectively). 24MY service releases available. DT was updated starting 25MY and beyond. If the vehicle to be repaired is a 24MY vehicle with a service release available, please follow the released service procedures to update to the corresponding calibration/software.

These conditions may be related to worn intake camshaft high lift lobe(s), and intake rocker arm(s) high lift slider. High mileage failure (10,000-60,000 miles). 1. Remove the valve cover(s) per the released service procedures. The use of a stethoscope or DTC specific cylinder misfire codes can help to locate the condition to the left or right bank. 2. Once it has been visually confirmed that there is wear on the high lift intake lobe(s) & rocker arm(s) slider, there is a special service kit for this type of repair which should be used, instead of replacing the complete engine/long block. This kit contains the parts required for the repair (intake cam, rocker arms, sealer and gaskets). Once it is confirmed that the repair will be done using the camshaft/Rocker arms kit, it is also important to confirm that the vehicle being repaired has the latest calibration/software update for oil pump operation mode (high pressure mode) during engine start up. RU, VF, WL & WD vehicles already include the latest oil pump mode in all 25MY and beyond. 24MY service releases are also available. JL & JT were updated as a running change in 24MY and beyond (08/15/24 & 08/19/24 respectively). 24MY service releases available. DT was updated starting 25MY and beyond. If the vehicle to be repaired is a 24MY vehicle with a service release available, please follow the released service procedures to update to the corresponding calibration/software update.

Inspect & check all electrical connections to the alternator a. 2-way connector containing field control circuit & alternator sense voltage circuit. b. Unplug & plug-in the 2-way connector for field & sense circuit. Verify the connection is tight & check for any bent pins in alternator connector or damage to female terminals in connector. c. Check Alternator B+ Stud connection to be sure nut is securing positive cable terminal properly (i.e. nut is clamping terminal & connection is tight). d. Check fuse between the alternator B+ stud & PDC terminal to make sure it is not blown. e. Be sure to follow service manual sections on ALTERNATOR CONTROL CIRCUIT DIAGNOSTIC & ALTERNATOR SENSE CIRCUIT DIAGNOSTIC looking for any opens & shorts (to ground or battery voltage). 2. Check/verify all grounds in the charging system circuit a. Check tightness of mounting bolts securing alternator to engine block. Alternator is a case ground component. b. Check main ground from engine to chassis; connection must be tight. c. Check battery ground cable connections are tight. d. Potentially, loosen alternator mounting bolts, without removing alternator, and re-tighten to torque specifications in service manual. e. After all steps above are complete, re-start engine & check charging system operation. 3. Verify that the Smart Charging System is not the reason for alternator low voltage & current output (Amps). a. Alternator charging can be suspended during engine idle operation because of the Smart Charge strategy. b. Refer to service manual section ""System Operation - Smart Charging System"". c. Refer to Star Case S2008000031 Rev A for low charging voltage & Smart Charge Mode Voltage Range diagram & mode descriptions. d. The alternator has no internal regulator; thus, has no smart circuitry. All alternator control signals come from ECM. 4. If alternator is faulty, remove alternator & mounting bolts. Return alternator with bolts for analysis at QEC."

PRIOR TO PERFORMING ANY WATER PUMP REPLACEMENT, PROCEED WITH INSPECTION INSTRUCTIONS FROM THE LATEST VERSION OF STAR ONLINE PUBLICATION S2307000002. Please submit pictures of the leak area thru the DIDI process outlined in the STAR Online document. NOTE: Some coolant residue may be found at the water pump weep hole plug area which may be normal, but coolant should not be dripping from this location. If unsure about, use the Pressurized Coolant System Inspection process as found in the Dealer Connect Cooling Diagnosis and Testing Procedures."

Customer complaints may include a noise coming from under de hood described as a squeal, screech, squeak, chirp or "belt related" noise and/or noisy tensioner/pulley. Please check Service Library for any STAR Online publications that may apply. Note: If it is found that the pulleys and/or tensioners are to blame for the noise please use an stethoscope or similar tool to determine the origin of the noise and include it in the narrative.
