Engine Oil Specifications and Capacities
For the 2001 Mitsubishi Galant 2.4L engine, the recommended viscosity is 10W-30 for temperatures above -18°C, though SAE 5W-30 is generally preferred for optimal protection across a wider temperature range. The engine requires 4.5 quarts of oil for a standard change, which includes the filter replacement. When performing the oil change, it is crucial to torque the oil drain plug to between 26 and 32 ft/lbs. Always check the oil level after refilling to ensure the correct amount is present.
Selecting the right oil type depends on the condition of your vehicle. If your Galant has accumulated significant mileage, specifically over 75,000 miles, the High-Mileage formula is an excellent choice to help seal leaks and reduce oil consumption. For newer or well-maintained engines, the Signature Series or Extended-Life formulas provide maximum cleaning power and wear protection. The AMSOIL Oil Filter is the recommended pairing for the synthetic motor oils, while WIX XP or standard WIX oil filters serve as excellent alternatives that meet the vehicle’s filtration needs.
Transmission and Cooling System Fluids
The automatic transmission fluid for the 2001 Galant is a critical component for smooth operation. The transmission capacity varies based on the fill method and specific model. For an initial fill, the system requires 3.7 quarts. However, a total fill, such as during a complete flush or after a transmission rebuild, will require significantly more fluid. The 4-speed F4A42-2 transmission requires a total of 8.1 quarts, while the F4A51-2 variant requires 8.9 quarts. Using a high-quality synthetic transmission fluid like the AMSOIL Signature Series ensures the transmission withstands heat and heavy loads without losing shifting quality.
Cooling system maintenance is equally vital for the longevity of the Mitsubishi 4G64 engine. The cooling system capacity is 7.4 quarts. AMSOIL offers two primary antifreeze options for this vehicle. The Passenger Car & Light Truck Antifreeze & Coolant is a convenient pre-mixed solution that protects for up to 150,000 miles. For those who prefer a concentrated fluid, the Propylene Glycol Antifreeze can be mixed with water to achieve a highly stable cooling solution that guards against corrosion and erosion for extended periods. Both formulations are designed to be compatible with the metals and gaskets used in this vehicle’s cooling system.
Brake, Power Steering, and Fuel Additives
The braking system on the Galant utilizes a hydraulic Brake Fluid. For this application, a DOT 3 or DOT 4 fluid is recommended. AMSOIL’s 100% Synthetic Brake Fluid ensures excellent responsiveness for ABS systems and maintains consistent viscosity even under extreme braking heat. This helps prevent brake fade and ensures safe stopping power.
Similarly, the power steering system benefits from a synthetic fluid. AMSOIL’s Multi-Vehicle Power Steering Fluid is formulated to keep seals soft, preventing leaks that are common in older vehicles. It offers strong anti-wear protection and high-temperature stability. Finally, to keep the fuel system clean and efficient, AMSOIL P.i. Performance Improver is a powerful additive that cleans carbon deposits from fuel injectors and combustion chambers, restoring lost horsepower and improving overall fuel economy.
