🔧 Maintenance

Recommended Oil Change Interval:

Typically every 3,000-7,500 miles or 6 months for gasoline engines, depending on driving conditions and oil type. Diesel engines may have different intervals, often based on mileage or operating hours.

Spark Plug Replacement Interval:

Varies by engine: 3.7L/4.7L V8 (standard copper plugs) ~30,000 miles; 5.7L HEMI (Double Platinum) ~100,000 miles. Diesel engines have glow plugs and do not use spark plugs in the same manner.

Air Filter Replacement Interval:

Typically every 15,000-30,000 miles or as needed based on operating conditions and inspection.

Fuel Filter Replacement Interval:

Varies by engine. For gasoline: often in the 30,000-60,000 mile range or as specified. Diesel fuel filter replacement is critical for the high-pressure fuel system and typically follows manufacturer recommendations based on mileage or time.

Coolant Flush Interval:

Typically every 30,000-60,000 miles or 2-5 years, depending on coolant type and manufacturer recommendation.

Engine Oil Specification:

Gasoline engines typically require 5W-30 or 10W-30 synthetic blend or full synthetic oil meeting Chrysler MS-6395. Cummins diesel engines typically require API CJ-4 or CK-4 rated 15W-40 or 5W-40 synthetic diesel engine oil.

Transmission Fluid Specification:

Gasoline Automatic: ATF+4 (MS-9602). Diesel Automatic (48RE): ATF+4 (MS-9602). Manual Transmissions: Gear oil (API GL-5) with appropriate viscosity (e.g., 75W-90, 75W-140). Transfer Case: ATF+4 (NV244), Mopar fluid or equivalent for NV271/273.

Brake Fluid Specification:

Power Steering Fluid Specification:

ATF+4 or Mopar Power Steering Fluid.

Differential Fluid Specification:

API GL-5, viscosity varies by temperature (e.g., 75W-90, 80W-90, 75W-140). Limited-slip differentials may require friction modifier.

Common Issues:

Early models of this generation could experience issues such as front suspension wear (ball joints, tie rods), brake component wear, EGR valve issues (diesel), and occasional electrical gremlins. The 4.7L V8 had a known issue with cylinder head casting porosity in some earlier production runs, though most 2005 models were less affected. Lifter tick in HEMI engines can occur with age and mileage.

Specific Diesel Issues:

For the 5.9L Cummins: Injector failures, CP3 injection pump issues, EGR valve problems, turbocharger wear, potential for cracked cylinder heads in high-mileage or modified engines.
