Additional Notes
- The cooling system capacity for the Chrysler Fifth Avenue (USA) is 15.6 liters, which represents a full system fill volume encompassing the radiator, engine block passages, heater core, and associated hoses.
- A 15.6-liter cooling system capacity is on the larger end for passenger cars of the late 1980s, reflecting the engine displacement and thermal management demands of the platform.
- The specified change interval under normal use conditions is 48,000 miles or 36 months, whichever comes first, meaning the coolant is expected to remain serviceable for up to three years before degradation of corrosion inhibitors and pH balance warrants replacement.
- The 36-month time limit on the normal-use interval acknowledges that coolant chemistry degrades over time regardless of mileage accumulation, making calendar age an independent trigger for service.
- The specifications cover the 1988-1989 model years as a single unified entry, indicating no variation in cooling system capacity or change interval between those two years for the USA-market Fifth Avenue.
