Mishimoto | 2007-2024 Dodge Ram 5.9L / 6.7L Cummins Stock Replacement Oil Cooler

Oil is the lifeblood of an engine, and in a hardworking diesel engine like the 2007+ Dodge Ram 5.9L/6.7L Cummins, keeping that oil cool is essential to the engine's health.

The stock 2007+ Dodge Ram 5.9L/6.7L Cummins liquid-to-liquid oil cooler uses engine coolant to draw heat away from the oil and vent it through the engine radiator. It's a stout design that typically performs well for daily driven trucks. However, after up to 16 years of service, many of those stock coolers have seen better days.

A clogged or leaking oil cooler can reduce the oil's ability to transfer heat to the coolant, causing thinning and a loss of protection for critical engine components. That's why Mishimoto is proud to offer a stock-style replacement 2007+ Dodge Ram 5.9L/6.7L Cummins oil cooler. This replacement cooler, complete with new seals, will restore and improve your 5.9L or 6.7L Cummins oil cooling and protect your engine from unnecessary wear.
