Proper lubrication is the cornerstone of maintaining the integrity of the 1985 Chrysler NEW YORKER. The engine specifications for this vehicle call for a 5W-30 viscosity grade, with a total capacity of 5.1 quarts when the filter is replaced. This capacity is a critical detail for any DIY maintenance session or professional service, ensuring that the oil level is correct after refilling. The vehicle’s engine operates best with SAE 5W-30 in temperatures below 38°C, though other grades like 10W-30 or 20W-40 can be used depending on the climate. By selecting a high-quality synthetic oil, you ensure that the turbocharger receives adequate lubrication even during the first few seconds of operation, reducing wear on sensitive bearing surfaces. Furthermore, synthetic oils offer superior thermal stability, which is essential for the turbocharged engine that experiences higher operating temperatures than naturally aspirated counterparts.
Essential Fluids for Transmission and Cooling
The automatic transmission in this New Yorker requires specific attention to prevent shifting issues and ensure smooth power delivery. The A413 (31TH) and A470 (31TH) transmission types are compatible with the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid and the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid. The total fill capacity for a 3-speed transmission is 8.9 quarts, with an initial fill of 4 quarts. Using a synthetic transmission fluid like AMSOIL helps resist sludge buildup and maintains fluid viscosity in extreme temperatures, which is crucial for the longevity of the torque converter and internal clutch packs. For vehicles that may have been sitting or for those looking to extend the service interval significantly, the synthetic options provide a robust barrier against oxidation and wear.
Cooling system maintenance is equally vital for a vehicle of this vintage. The 1985 NEW YORKER holds 9 quarts of Antifreeze & Coolant. AMSOIL offers two distinct options for this application: the Passenger Car & Light Truck Antifreeze & Coolant, which is a ready-to-use 50/50 pre-mix, and the Propylene Glycol Antifreeze and Engine Coolant, a concentrated formula that requires mixing with distilled water. Both options provide up to 150,000 miles of protection and are free of phosphates, nitrates, nitrites, silicates, borates, and amines, making them safe for all cooling system metals, gaskets, and hoses. The Propylene Glycol variant offers additional protection for severe applications, capable of lasting up to 1,000,000 miles or 8 years in heavy-duty scenarios, though the standard recommendation for this passenger car is sufficient for typical ownership cycles.
Brake and Power Steering System Care
Ensuring safety and ease of operation is paramount for the 1985 Chrysler NEW YORKER. The brake system relies on hydraulic fluid that must remain stable under high heat and pressure. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is the recommended choice, offering excellent responsiveness for ABS systems and maintaining viscosity over a wide temperature range. This fluid helps prevent the moisture absorption that can lead to corrosion within the brake lines and calipers, a common issue in older vehicles.
Similarly, the power steering system benefits from AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid. This fluid is formulated to reduce friction, helping seals remain soft to prevent leaks, which is a common concern as rubber components age. It resists heat degradation, ensuring long fluid life and quiet operation. By using these specialized fluids, you not only protect the specific components but also enhance the overall driving experience, ensuring that the steering feels responsive and the brakes remain reliable for years to come.
Seasonal and Fuel System Maintenance
For owners who engage in seasonal driving patterns, AMSOIL offers a Gasoline Stabilizer that keeps fuel fresh for up to 12 months. This is particularly useful for stored equipment or vehicles that are driven infrequently, as it prevents varnish and gum buildup and fights ethanol corrosion. Additionally, the P.i.® Performance Improver gasoline additive can restore up to 14% of lost horsepower and clean fuel injectors, which is beneficial for maintaining the efficiency of the 2.2L engine over time. These additives work in tandem with the high-quality lubricants to ensure the entire powertrain operates at its peak potential.
