The engine oil for this Grand AM is critical for maintaining the health of the 2.2L L61 F engine. The recommended oil grade is SAE 5W-30, which is preferred for all temperature conditions. The system holds 5.0 quarts when the AMSOIL Oil Filter is included. After refilling, it is important to check the oil level to ensure the correct amount is present. The oil drain plug should be torqued to 18 ft/lbs to prevent leaks or damage. Using a synthetic motor oil like the Signature Series, Extended-Life, or OE varieties ensures that your engine receives 75% more protection against horsepower loss and wear compared to conventional oils. These formulations also help prevent Low-Speed Pre-Ignition (LSPI), a condition that can cause significant engine damage, particularly in modern turbocharged engines though protection is vital for any engine longevity.
Transmission and Cooling System Maintenance
The 2004 Pontiac Grand AM with the 2.2L engine typically utilizes a 4T40-E automatic transmission. This transmission requires fluid that meets the updated Dexron VI specification, as noted by manufacturer Technical Service Bulletins. A total fill for the 4-speed transmission requires 12.9 quarts, while an initial fill calls for 6.9 quarts. AMSOIL synthetic transmission fluids are engineered to withstand the rigors of heavy towing and elevated operating temperatures while remaining fluid in sub-zero conditions. They provide a reserve of protection during heavy use and abuse, reducing the risk of sludge and ensuring smooth, shudder-free shifts. Whether you choose the Signature Series Fuel-Efficient, OE Fuel-Efficient, Signature Series Multi-Vehicle, or OE Multi-Vehicle fluids, you are selecting a lubricant that resists harmful deposits and protects against wear.
Cooling system maintenance is equally vital for the longevity of the Grand AM. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant capacity for this vehicle is 8.7 quarts. For this application, this is recommended as a 50/50 pre-mix. This unique poly-organic acid (OAT) formulation allows for use in a wide variety of vehicles and protects all cooling system metals, gaskets, and hoses. It is free of phosphates, nitrates, nitrites, silicates, borates, and amines, which can sometimes cause corrosion in older systems. This coolant offers protection for up to 150,000 miles or five years. Alternatively, the concentrated AMSOIL Propylene Glycol Antifreeze and Engine Coolant requires mixing with distilled water and offers extended protection up to 150,000 miles for passenger cars and light trucks.
Other Essential Fluids and Filters
Beyond oil and transmission fluid, the braking and steering systems of the Grand AM require attention to safety and handling. The recommended AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid for this vehicle is a hydraulic brake fluid meeting DOT 3 specifications (P/N 12345347, spec. 9985642). This synthetic fluid provides excellent responsiveness for ABS and traction-control systems. It maintains a stable viscosity over a wide temperature range, ensuring reliable braking performance in all weather conditions. For power steering, the vehicle uses a system designated as PS004. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is the ideal choice, as it reduces friction, resists heat for long fluid life, and helps seals remain soft to prevent leaks. This fluid is formulated for quiet operation and provides strong anti-wear protection.
Vehicle Background
Released in the late 1990s and continuing into the 2000s, the Pontiac Grand AM was a staple in the mid-size sedan market.
