6. Have appropriate fluid disposal containers ready

Procedure

1. 1

   Raise and support vehicle
   Raise vehicle using floor jack at manufacturer-specified jacking points. Support vehicle securely on four jack stands at frame rails. Verify stability before working underneath. Remove all four wheels for brake and suspension inspection.
2. 2

   Drain engine oil
   Position drain pan under engine oil pan. Locate and remove the engine oil drain plug on the bottom of the oil pan. Allow oil to drain completely (approximately 15 minutes due to large capacity). Inspect drain plug threads and replace crush washer. Reinstall drain plug and torque to specification.
3. 3

   Replace engine oil filter and refill oil
   Locate oil filter on driver side of engine block. Use oil filter wrench to remove old filter. Clean filter mounting surface on engine block. Apply thin film of new oil to new filter gasket. Install new filter hand-tight, then turn an additional 3/4 turn. Refill engine with 11.0 quarts of 0W-40 full synthetic oil through oil filler cap. Start engine and check for leaks. Shut off and verify oil level on dipstick after 2 minutes.
4. 4

   Drain and refill coolant system
   Place large drain pan under radiator. Open radiator drain petcock at bottom of radiator. Remove radiator cap to allow complete drainage. Once fully drained, close petcock and inspect all coolant hoses for cracks, softness, or swelling. Refill system slowly with 19.0 quarts of Mopar HOAT 50/50 coolant through radiator filler neck and overflow reservoir. Start engine with radiator cap off and allow to reach operating temperature while adding coolant as level drops. Once thermostat opens and coolant circulates, top off and install radiator cap. Check overflow reservoir level and adjust to FULL COLD mark.
5. 5

   Replace engine air filter
   Open hood and locate air filter housing on driver side of engine compartment. Release the housing clamps (typically 4 spring clips or fasteners). Separate housing halves and remove old air filter. Inspect housing for debris and clean if necessary. Install new air filter ensuring proper orientation and seating. Reassemble housing and secure all clamps.
6. 6

   Replace spark plugs
   Remove engine cover by releasing fasteners. Locate all 10 spark plug coil packs (5 per cylinder bank). Disconnect electrical connectors from each coil pack. Remove coil pack hold-down bolts and pull coil packs straight out. Use compressed air to clean debris from spark plug wells. Using 14mm spark plug socket with extension, remove all 10 spark plugs. Inspect old plugs for abnormal wear patterns. Gap new spark plugs to OEM specification (verify per service manual) and install without anti-seize unless specified by the plug manufacturer. Install new plugs hand-tight, then torque to specification. Reinstall coil packs and reconnect electrical connectors. Reinstall engine cover.
7. 7

   Service manual transmission
   Locate transmission fill plug on driver side of transmission case and drain plug on bottom. Remove fill plug first (always remove fill plug before drain plug to avoid being unable to refill). Remove drain plug and allow fluid to drain completely into drain pan. Inspect drain plug magnet for excessive metallic debris. Clean magnet and replace drain plug crush washer. Reinstall drain plug and torque to specification. Using fluid pump, refill transmission through fill hole with the OEM-specified quantity of the manufacturer-specified manual transmission fluid until fluid begins to seep from fill hole. Reinstall fill plug and torque to specification.
8. 8

   Service rear differential
   Locate rear differential fill plug on front face of differential housing and drain plug on bottom of housing. Remove fill plug first. Remove drain plug and drain fluid completely. Inspect drain plug magnet for excessive debris. Clean magnet and replace drain plug crush washer. Reinstall drain plug and torque to specification. Using gear oil pump, refill differential through fill hole with 2.75 quarts of 75W-90 synthetic gear oil until fluid reaches bottom of fill hole threads. Reinstall fill plug and torque to specification.
9. 9

   Inspect and service brake system
   With wheels removed, thoroughly inspect brake pads for remaining thickness (minimum 3mm). Inspect brake rotors for scoring, heat checking, or excessive wear. Measure rotor thickness with micrometer and compare to minimum specification stamped on rotor. Inspect brake lines and hoses for cracking, chafing, or leakage. Check brake fluid level in master cylinder reservoir. If fluid is dark or contaminated, perform complete brake fluid flush by bleeding all four corners starting with right rear, then left rear, right front, and left front. Top off reservoir with fresh DOT 4 brake fluid to MAX line.
10. 10

    Inspect suspension and steering components
    Inspect all suspension bushings for cracking, tearing, or deterioration. Check ball joint boots for tears or grease leakage. Inspect tie rod ends and boots for wear or damage. Check shock absorbers for fluid leakage. Inspect sway bar end links and bushings. With wheels off ground, check for excessive play in wheel bearings by grasping tire at 12 and 6 o'clock positions and attempting to rock wheel. Check power steering fluid level in reservoir and top off with Mopar ATF+4 if needed. Inspect power steering hoses for leakage or damage.
11. 11

    Inspect exhaust system and underbody
    Visually inspect entire exhaust system from headers to tailpipes for leaks, damage, or loose components. Check exhaust hangers for deterioration. Inspect fuel lines and connections for leakage or damage. Check driveshaft boots for tears or grease leakage. Inspect chassis and underbody for damage, corrosion, or fluid leaks.
12. 12

    Inspect belts and hoses
    Inspect serpentine belt for cracking, fraying, glazing, or contamination. Check belt tensioner operation and condition. Inspect all coolant hoses, heater hoses, and connections for softness, cracking, or swelling. Check clamps for tightness. Inspect any vacuum hoses for cracking or deterioration.
13. 13

    Reinstall wheels and lower vehicle
    Reinstall all four wheels, starting lug nuts by hand. Torque lug nuts in star pattern to manufacturer specification. Lower vehicle from jack stands carefully and remove stands. Lower vehicle completely to ground. Perform final torque check on all lug nuts with vehicle on ground. Remove wheel chocks.
14. 14

    Check and adjust tire pressures
    Check tire pressure in all four tires with accurate gauge. Refer to door jamb placard for correct pressure specifications and set to the placard values. Adjust pressures as needed. Inspect tires for uneven wear, cuts, bulges, or foreign objects.
15. 15

    Final inspection and test drive
    Check all fluid levels one final time (engine oil, coolant, brake fluid, power steering fluid). Verify all fasteners, caps, and plugs have been reinstalled. Start engine and allow to idle for 5 minutes, checking for any leaks or unusual noises. Perform test drive, checking operation of all systems. Monitor temperature gauge and check for smooth shifting. After test drive, recheck for any leaks and verify proper operation.

Reassembly

1. Torque all drain plugs to manufacturer specifications using new crush washers
2. All coil packs must be fully seated with electrical connectors firmly clicked into place
3. Ensure radiator cap is properly installed after coolant system is bled
4. Verify all fill plugs (transmission and differential) are reinstalled before lowering vehicle
5. All wheels must be torqued in star pattern with vehicle on ground for final check

Verification

• Start engine and verify oil pressure light extinguishes immediately
• Check for any fluid leaks under vehicle after running engine to operating temperature
• Verify coolant system is properly bled with no air pockets (heater blows hot air)
• Confirm smooth engine idle with no misfires after spark plug replacement
• Test drive vehicle and verify smooth transmission shifting and proper brake operation
• Verify all warning lights are off on instrument cluster
• Recheck all fluid levels after test drive and top off as necessary
