Proper lubrication is the foundation of a healthy engine. For the 2014 Ram ProMaster 3500, the choice between AMSOIL Signature Series, Extended-Life, OE, or High-Mileage motor oils depends largely on the vehicle’s mileage and the driver’s maintenance schedule. All recommended oils meet the 5W-20 viscosity requirement for all temperatures. The engine holds 5.9 quarts of oil when the AMSOIL Oil Filter is changed. Adhering to the correct torque specifications of 20 ft/lbs for the oil drain plug ensures a secure seal, while using the recommended fuel additives can further enhance performance if the vehicle runs on E85 or M85 fuels.
Transmission and Cooling Systems
The transmission and cooling systems are equally critical for the longevity of the ProMaster. The 6-speed automatic transmission (62TE) requires specific attention. A total fill requires 9 quarts, while an initial fill after a drain uses 5.5 quarts. AMSOIL offers two primary choices: the Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid for severe service conditions like heavy towing, and the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid for standard operation. Both are 100% synthetic and formulated to resist sludge and ensure smooth shifting.
For the cooling system, the vehicle requires 10.6 quarts of AMSOIL Propylene Glycol Antifreeze and Engine Coolant. Owners can choose between the Passenger Car & Light Truck Antifreeze & Coolant, which is pre-mixed for immediate use, or the Propylene Glycol version for those who prefer a concentrated solution. Both products are phosphate, nitrate, nitrite, silicate, borate, and amine-free, ensuring compatibility with all cooling system metals and hoses while providing protection for up to 150,000 miles or 5 years.
Fluid Maintenance and Vehicle Care
Beyond engine and transmission care, maintaining the brake and power steering systems ensures safe and quiet operation. The brake system requires MOPAR DOT 4 fluid, which is perfectly matched by the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid. This fluid maintains stable viscosity, ensuring reliable braking performance in extreme temperatures. Similarly, the power steering system benefits from the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid, which is designed to remain fluid in extreme cold and resist thermal breakdown under heat.
For vehicles that are driven in dusty environments or subjected to frequent washes, AMSOIL offers a comprehensive range of cleaning and protection products. From the AMSOIL Heavy-Duty Degreaser that removes tough grime to the AMSOIL Mudslinger Mud and Dirt Repellent that keeps the exterior clean, these products help maintain the vehicle’s appearance and condition. Additionally, fuel system maintenance can be improved with the AMSOIL P.i. Performance Improver, which restores horsepower and cleans GDI fuel injectors.
About the 2014 Ram ProMaster 3500
The 2014 Ram ProMaster 3500 represents a significant milestone for the Ram brand and the commercial van segment. Introduced to the North American market in 2014 as part of the Fiat Ducato platform, the ProMaster was designed from the ground up to compete with other high-volume cargo and passenger vans. Unlike the traditional body-on-frame trucks of the past, the ProMaster utilizes a unibody construction that offers a lower load floor, making loading and unloading easier and improving the center of gravity for better handling.
Under the hood, the 3.6-liter Pentastar V-6 engine, identified by engine code G ERB, provides a robust balance of power and efficiency. This engine is known for its durability and has been a staple in Chrysler Group vehicles for years. The ProMaster 3500 is the heavy-duty variant of the lineup, featuring a Gross Vehicle Weight Rating (GVWR) that allows it to carry significant payloads. Its front-wheel-drive configuration contributes to interior space efficiency, offering up to 472 cubic feet of cargo volume depending on the roof height and wheelbase configuration. This combination of a versatile unibody chassis, a reliable V-6 powerplant, and a spacious interior makes the ProMaster 3500 a preferred choice for tradespeople, delivery services, and fleet operators who require a dependable work vehicle capable of handling demanding daily routes.
