Detailed Product Overview

Part number 3657 is a premium new A/C condenser engineered to match original equipment dimensions and function for Ram heavy-duty cooling service. The parallel flow core, aluminum tubes, and louvered fins are built to improve heat transfer, while the furnace-brazed construction adds structural integrity. This condenser is a direct service choice for 2003-2006 Dodge Ram 2500 and 2003-2006 Dodge Ram 3500 models equipped for CAC with plastic tanks.

Common Problems This Part Can Address

• Reduced A/C cooling performance from a leaking or restricted condenser
• Visible damage to condenser fins or tubes from road debris
• Loss of refrigerant pressure caused by corrosion or impact damage
• Uneven cabin cooling due to poor heat rejection at the condenser
• Fitment issues when replacing an OE-style condenser on Ram HD trucks

Installation Notes and Tips

Verify the vehicle uses block inlet and outlet fittings before installation. Confirm the application is for CAC with plastic tanks on the listed Dodge Ram 2500 or Ram 3500 model years. Inspect related A/C components, flush the system as needed, and evacuate and recharge the refrigerant system according to factory service procedures after replacement.

Quality Assurance

Each condenser is individually pressure tested before release. The design follows OE-style form and function, with aluminum construction and furnace-brazed joints selected for consistent heat dissipation and durability in HVAC service.
