Oil is the lifeblood of an engine, and in a hardworking diesel engine like the 2003-2007 Dodge RAM 5.9L Cummins, keeping that oil cool is essential to the engine's health. ---- 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.
