Understanding the specific fluid capacities and service intervals for this classic Dodge is essential for a successful maintenance routine. For the 2.2L 4-cylinder engine, the oil capacity is 4 quarts when including a filter change. The drain plug should be torqued to 20 ft/lbs to ensure a secure seal without risking thread damage. When filling the cooling system, the capacity is approximately 9 quarts, making it vital to use a high-quality AMSOIL Passenger Car & Light Truck Antifreeze & Coolant that prevents rust and boiling. The automatic transmission, specifically the A413 (31TH) model, requires an initial fill of 4 quarts and a total fill of 8.9 quarts. Manual transmissions vary by gear count, with capacities generally falling between 3.8 and 4.4 pints. By adhering to these specifications and utilizing full-synthetic fluids, you ensure that the vehicle’s original engineering is preserved and enhanced.
Comprehensive Lubrication and Protection
While AMSOIL OE Motor Oil is the lifeblood of the engine, a complete lubrication regimen for the 1987 Dodge 600 involves several critical areas that often go overlooked. The brake system, for instance, relies on hydraulic fluid that must resist moisture absorption and boiling to maintain safety. Using AMSOIL DOT 3 and DOT 4 synthetic brake fluid ensures that the braking system remains responsive, providing excellent traction-control performance even under stress. Similarly, the power steering system benefits from a synthetic fluid that resists heat degradation and keeps seals pliable, preventing the leaks and whining noises that often accompany older steering racks.
For those looking to add performance to their restoration or daily driver, fuel system maintenance is equally important. The AMSOIL P.i. Performance Improver gasoline additive can restore up to 14% horsepower and rejuvenate fuel injectors, which is particularly beneficial for an engine of this vintage that may have accumulated carbon deposits. Furthermore, during storage periods, the use of AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against the varnish and gum buildup that can foul carburetors and injectors. For long-term storage, an engine fogging oil can be used to coat internal components, preventing rust and corrosion while the vehicle sits idle.
About the Vehicle
The 1987 Dodge 600 represents a significant era for Chrysler’s lineup, serving as a budget-friendly alternative to the larger and more expensive Chrysler LeBaron and New Yorker models. Part of the compact A-body platform, the Dodge 600 was designed to offer reliable transportation at an accessible price point. It typically arrived as a sedan, competing in a crowded segment dominated by American-made compacts from Ford and General Motors. The 2.2L engine, known for its compact design and efficient performance, became a staple of the 1980s Chrysler engine family. This powerplant was celebrated for its balance of fuel economy and decent torque, making it a popular choice for commuters and budget-conscious families alike.
Despite its practical reputation, the 1987 Dodge 600 is not without its maintenance quirks, many of which can be effectively mitigated with the use of high-quality synthetic lubricants. One common issue associated with the 2.2L engine is the tendency for oil to degrade faster in higher-mileage vehicles, leading to sludge buildup that can clog oil passages and strain the pump. Switching to a full-synthetic oil with a robust detergent package helps combat this aging process, keeping the engine internals cleaner for longer periods. Another challenge often faced by owners of this model is AMSOIL Propylene Glycol Antifreeze and Engine Coolant system corrosion over time. The original cooling systems can be prone to rust and scale formation, which restricts flow and causes overheating. Using a premium antifreeze with advanced corrosion inhibitors protects the radiator, water pump, and engine block from these degradation effects.
Seal and gasket deterioration is a third concern for this vintage vehicle. As rubber components age, they can harden and shrink, leading to oil leaks around the valve covers or the oil pan. Synthetic oils and high-mileage formulations contain additives designed to swell and condition seals, helping to restore their flexibility and stop minor leaks without the need for immediate mechanical intervention. Finally, transmission wear in automatic models can result in rough shifting or hesitation. The use of a dedicated synthetic transmission fluid helps maintain proper friction characteristics, ensuring that the transmission shifts smoothly and resists the sludge that often leads to premature wear in older automatic units.
The legacy of the Dodge 600 is one of practicality and durability. Owners who prioritize regular maintenance with premium fluids find that these vehicles can continue to perform reliably well beyond their original design life. Whether it is a daily commuter or a weekend restoration project, applying the best available lubrication technology ensures that the mechanical integrity of this classic compact remains intact. By focusing on the specific needs of the 2.2L engine and its accompanying systems, you can enjoy the driving experience of a vehicle that combines straightforward engineering with the modern advantages of synthetic protection.
