Chrysler Group vehicle fluid systems do NOT require regular flushing. These systems include: engine oil, transmission oil, axle lube, brake fluid, power steering fluid, and refrigerant. The only exceptions to this requirement are published in the vehicle maintenance schedules, e.g. engine coolant.
Exceptions to this recommendation include only those instances where a malfunction has occurred and/or the system has become compromised, contaminated or overheated beyond the normal operating range.
Chrysler Group does NOT recommend aftermarket chemicals to flush the engine, transmission, brake or steering systems. Chemicals contained in these products can damage the system elastomeric components, and contaminate the component fluid, leading to loss of system/component durability and service life. When necessary, only the original approved system fluid should be used to flush these components using teamPSEŽ approved equipment.
If the engine coolant contains a considerable amount of sediment, clean and flush with Mopar Cooling System Flush, p/n 04856977, or equivalent. Follow with a thorough rinsing to remove all deposits and chemicals. Refill with a minimum of a 50% mixture of the specified coolant and distilled water.
