Mishimoto MMOC-RAM-03 Replacement Oil Cooler for 2003-2007 Dodge Ram 2500/3500 (5.9L)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2003-2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins engine.
Maintaining stable oil temperatures is essential for the longevity of the high-torque 5.9L Cummins diesel engine. Over time, factory oil coolers can become clogged with debris or develop internal leaks, significantly reducing the system's ability to transfer heat to the coolant. This results in oil thinning and a loss of protection for critical internal engine components. The Mishimoto MMOC-RAM-03 is a direct-fit, stock-style replacement designed to restore your engine's thermal efficiency and reliability.
Engineered to meet OEM quality standards, this oil cooler provides the necessary heat dissipation for daily driving and heavy-duty towing. The kit includes all required gaskets and seals to ensure a leak-free installation into the factory mounting location.
- Direct-fit for 2003-2007 Dodge Ram 2500/3500 with 5.9L Cummins engine
- Replaces clogged or leaking factory units to prevent oil thinning and engine wear
- Includes all necessary gaskets and seals for a complete installation
