• Replacement for damaged or leaking radiators in Ram 2500 and 3500 trucks
• Resolves overheating issues caused by inefficient or clogged cooling systems
• Addresses coolant leaks from cracked or corroded radiator tanks
• Improves engine temperature control during heavy towing or hauling
• Suitable for restoring OEM cooling performance in older or high-mileage vehicles

Installation Notes and Tips

Ensure compatibility with your Ram 2500 or 3500 model before installation. The radiator does not include a cap, so reuse the existing cap or purchase separately if needed. Properly flush the cooling system prior to installation to prevent contamination. Verify inlet and outlet hose sizes (1 3/8 inches) match your vehicle’s hoses for a secure fit. Follow manufacturer torque specifications when securing the radiator to avoid damage.
