Mishimoto 07-20 Dodge RAM 5.9L/6.7L Cummins Stock Replacement Oil Cooler

If you're working on a 2007-2024 Ram truck with a 5.9L or 6.7L Cummins engine, keeping the oil cool is a big part of keeping that engine healthy. The stock liquid-to-liquid oil cooler uses your engine's coolant to pull heat away from the oil, and it usually does a solid job for daily driving. But after years of service, these coolers can get clogged or start to leak, which means your oil can't shed heat properly. That leads to thinner oil and less protection for your engine's vital parts.

That's where this Mishimoto stock-style replacement oil cooler comes in. It's built to meet OEM quality standards, so it'll restore your Cummins' oil cooling performance. This cooler comes with new seals and everything you need for installation, making it a straightforward swap to get your engine protected again. It's a well-built part that provides all the cooling a daily-driven Cummins needs.

This cooler is designed as a direct fit for your truck. Mishimoto backs this part with their Lifetime Warranty, so you can drive with confidence knowing it's built to last.
