Complete Lubrication Guide for Your Dodge RAM 3500
Beyond the engine, your RAM 3500 requires attention to several other fluid systems to maintain its heavy-duty capabilities. Whether you are navigating steep grades, hauling heavy loads, or driving through extreme temperatures, using the correct synthetic fluids is essential for protecting your investment.
Transmission Fluid for Towing and Hauling
The transmission in your 2009 RAM 3500 is a critical component that handles significant torque. Depending on your specific configuration, you may have a 6-speed AS68RC or a 5-speed 545RFE. For RWD models, the total fill capacity for the AS68RC is 13.7 quarts, with an initial fill of 7.2 quarts. The 5-speed 545RFE RWD requires 16.9 quarts total, with 5.5 quarts initial. For 4WD models equipped with the 5-speed 545RFE, the total fill is 16.9 quarts with an initial fill of 6.6 quarts.
To ensure smooth shifts and protect against sludge, AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is the preferred choice. It is designed to withstand the rigors of heavy towing and elevated temperatures while remaining fluid in sub-zero conditions. For those seeking OEM-matching performance at a competitive value, AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid offers excellent cold-weather performance and resistance to harmful sludge. Additionally, the WIX Transmission Filter helps remove contaminants to extend the life of your transmission fluid and components.
Antifreeze and Coolant Systems
The cooling system in your Dodge RAM 3500 holds approximately 18.7 quarts of fluid. Maintaining the correct coolant mixture is vital to prevent overheating and corrosion. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid (OAT) formulation that allows for use in a wide variety of vehicles. It provides protection up to 150,000 miles or 5 years and is compatible with all other antifreeze colors. For those who prefer a concentrated product, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers extended protection up to 150,000 miles and greatly surpasses standards for metallic corrosion.
Differential and Transfer Case Lubricants
The front and rear differentials, as well as the transfer case, require high-performance gear lubricants to handle the torque and friction of a heavy-duty truck. For front limited slip differentials and standard differentials, the AMSOIL catalog recommends AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube. This product contains friction modifiers for limited-slip applications and helps control thermal runaway. If you require a thicker viscosity for specific axle setups, AMSOIL SEVERE GEAR 75W-110 provides advanced protection. For heavier applications or specific rear differential needs, AMSOIL SEVERE GEAR 75W-140 and AMSOIL SEVERE GEAR 80W-90 are available to ensure your gears are fully protected against rust, corrosion, and excessive wear.
Brake Fluid and Maintenance
Safety is paramount, and your brake system relies on high-quality fluid for responsive stopping power. The 2009 RAM 3500 utilizes hydraulic brake fluid that meets DOT 3 and DOT 4 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers excellent ABS and traction-control responsiveness with a stable viscosity over a wide temperature range, ensuring consistent pedal feel even during heavy braking.
Seasonal Storage and Vehicle Care
When the truck is not in use, protecting it from moisture and fuel degradation is essential. AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog injectors. For long-term engine protection during storage, AMSOIL Engine Fogging Oil is highly effective at preventing rust on internal components. Keep the vehicle’s appearance and performance in top condition with specialized care products. Use AMSOIL Miracle Wash Waterless Wash and Wax Spray for a fast, soap-free cleaning that protects against UV rays. For tough grime on the engine bay, AMSOIL Engine Degreaser provides a professional-strength formula. Clean glass streak-free with AMSOIL Glass Cleaner. For heavy-duty cleaning and waxing, the AMSOIL High-Foam Car Shampoo is hard on dirt but gentle on coatings. Finish with a durable shine using the AMSOIL Exterior Ceramic Spray. Interior surfaces can be cleaned with AMSOIL Interior Detailer – Light Lemon or the Scent Free version. Keep metal parts protected against rust with AMSOIL Heavy-Duty Metal Protector or AMSOIL MP Metal Protector. For general use, AMSOIL Silicone Spray offers a dry lubricating film, while AMSOIL Heavy-Duty Degreaser dissolves tough oil and tar.
