The engine lubrication system for the 2001 Grand AM’s 2.4L engine requires 4.0 quarts of fluid when performing a standard oil change including the filter. SAE 5W-30 is the preferred viscosity for all temperatures, though 10W-30 is an acceptable alternative when ambient temperatures remain above -18°C. When refilling, ensure the oil level is checked carefully after the refill is complete. The oil drain plug should be torqued to 19 ft/lbs to ensure a secure seal. Choosing a synthetic oil like AMSOIL Signature Series allows for extended drain intervals, reducing the frequency of maintenance while providing superior protection against the horsepower loss and wear that older engines often experience. For those with higher mileage, the AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil is specifically designed for vehicles with over 75,000 miles.
Transmission and Coolant Requirements
Proper transmission maintenance is critical for the smooth operation of the Grand AM. Depending on whether the vehicle is equipped with a 4T45-E or 4T40-E automatic transmission, the total fluid capacity can be significantly high, with a total fill requirement of 12.9 quarts for a complete flush. An initial fill typically requires 6.9 quarts. Note that specifications have been updated from Dexron II or III to Dexron VI, so a fluid meeting the newer standard is required. AMSOIL Signature Series Fuel-Efficient Synthetic ATF is engineered to withstand the rigors of heavy towing and elevated temperatures, ensuring the transmission remains fluid even in sub-zero conditions. For those preferring a fluid that meets OEM requirements exactly, the OE Fuel-Efficient Synthetic ATF provides excellent protection against wear while promoting shudder-free shifts. When performing a service, the AMSOIL WIX Transmission Filter offers premium media to protect the system from contaminants. Additionally, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is available for reliable protection.
The cooling system is equally vital, holding a capacity of 11.1 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid formulation that protects all cooling system metals, gaskets, and hoses. It is a 50/50 pre-mix, making it easy to use, and is phosphate, nitrate, nitrite, silicate, borate, and amine-free to ensure compatibility with the vehicle’s materials. For those who prefer a concentrated option, AMSOIL Propylene Glycol Antifreeze offers exceptional corrosion protection and a service life of up to 150,000 miles. Alternatively, the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid can be used for versatile protection.
Additional Fluid Maintenance
Brake fluid safety cannot be overlooked. The Grand AM utilizes hydraulic brake fluid meeting DOT 3 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers superior performance with excellent responsiveness for ABS and traction control systems. It maintains stable viscosity across a wide temperature range, ensuring consistent braking performance in both winter and summer conditions. For the power steering system, AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is recommended. It reduces friction, prevents leaks by keeping seals soft, and provides strong anti-wear protection even under high-temperature operation. Another option for transmission care is the AMSOIL Torque-Drive® 100% Synthetic Automatic Transmission Fluid.
Fuel system maintenance is another area where synthetic technology shines. The AMSOIL P.i.® Performance Improver Gasoline Additive is highly effective, capable of restoring up to 14% horsepower and cleaning GDI fuel injectors back to 100% flow rate after just one tank of fuel. It helps prevent carbon buildup and controls pre-ignition knock, ensuring the engine runs smoothly and efficiently. For seasonal storage, AMSOIL Gasoline Stabilizer helps keep fuel fresh, while Engine Fogging Oil protects internal components. Additionally, the WIX Fuel Filters offer improvements over original equipment standards. To maintain optimal fuel system performance, the AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor lubricates the fuel system.
