Proper lubrication begins with the heart of the vehicle: the engine oil. For the 1.6L 4-cylinder engine, the recommended oil capacity is 4.2 quarts when including a filter change. After the refill, it is crucial to check the oil level to ensure proper operation. The oil drain plug should be torqued to between 44 and 57 ft/lbs to prevent leaks or damage. AMSOIL offers a range of 10W-30 synthetic options to suit different driving needs and vehicle mileages. The Signature Series provides maximum protection against wear, while the High-Mileage formula is ideal for older engines that may need extra detergents and seal conditioners. Each of these oils is designed to outlast conventional oils, ensuring your engine stays clean and protected for extended periods.
Once the oil is changed, attention should turn to the filtration system. A high-quality oil filter is essential to trap contaminants and keep the new oil clean. The WIX Oil Filter included in the recommendations offers media that exceeds original equipment standards, ensuring maximum flow and filtration efficiency. This combination of premium oil and an effective filter creates a robust defense against the buildup of sludge and metal particles that can degrade engine performance over time.
Beyond the engine, the cooling system plays a vital role in maintaining the vehicle’s reliability. The 1984 Dodge COLT requires a capacity of 4.8 quarts of antifreeze. AMSOIL provides two excellent choices for coolant. The Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix that protects against corrosion and is compatible with all other coolant colors. For those who prefer to mix their own, the Propylene Glycol Antifreeze offers concentrated protection that can last up to 150,000 miles or five years. Both formulations are free from harmful phosphates and silicates, ensuring the longevity of the radiator, hoses, and gaskets within the cooling system.
Transmission health is equally important for the smooth operation of the vehicle. For the automatic transmission, the total fill capacity is 6 quarts, with an initial fill of 4.2 quarts. The recommended fluid is the Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid, which is engineered to handle the rigors of heavy towing and high temperatures. Alternatively, the OE Multi-Vehicle fluid offers a cost-effective synthetic option that resists sludge and promotes shudder-free shifts. If your COLT is equipped with a manual transmission, the 75W-90 Manual Transmission & Transaxle Gear Lube is the ideal choice. With a capacity of 4.9 pints, this fluid protects brass synchronizers and provides excellent seal compatibility, ensuring smooth gear changes in all weather conditions. The drain and fill plugs should be torqued to between 22 and 25 ft/lbs.
The safety systems of the vehicle also require maintenance. The hydraulic brake fluid should be a high-quality synthetic DOT 3 and DOT 4 fluid. This specific brake fluid provides stable viscosity across a wide temperature range, ensuring responsive braking even under heavy use. Using the correct fluid prevents brake fade and maintains the integrity of the ABS and traction-control systems. For power steering, which operates on automatic transmission fluid in this model, the recommended Signature Series or OE Multi-Vehicle transmission fluid serves a dual purpose, ensuring the system remains lubricated and protected from leaks.
For vehicle owners who put their cars through storage or infrequent use, AMSOIL offers specialized additives. The Gasoline Stabilizer helps keep fuel fresh for up to 12 months, fighting varnish and gum buildup caused by ethanol corrosion. Additionally, the Engine Fogging Oil provides a protective coating on internal components to prevent rust during long periods of inactivity. These products ensure that when you do start the engine again, it is protected from the corrosion that often plagues vehicles left sitting for extended periods.
