Oil is the lifeblood of an engine, and in a hardworking diesel engine like the 2008–2010 6. 4L Powerstroke, keeping that oil cool is essential to the engine's health and running. The stock 2008–2010 Powerstroke 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 over 10 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 replacement 2008–2010 Ford 6. 4L Powerstroke oil cooler. This replacement cooler, complete with new seals and O-rings will restore your 6. 4L Powerstroke’s oil cooling and protect your engine from unnecessary wear. This cooler is compatible with and provides all the cooling a daily driven 6. 4L needs at an affordable price point. Like all Mishimoto 6. 4L Powerstroke products, this stock replacement oil cooler is backed by our Mishimoto Lifetime for a lifetime of worry-free driving.
