It calls for the removal of both the intercooler and the upper radiator support, along with disconnecting the transmission cooler bolts, transmission cooler lines and A/C condenser from the radiator. Pulling the radiator on an ’08-’10 6.4L Power Stroke is very straightforward, but it is a bit involved. Follow along as we pinpoint the spot where the factory radiators fail and prove why the Mishimoto radiator outperforms and outlasts the factory piece. We recently installed one of Mishimoto’s aluminum radiators on a ’10 F-250, a process that took roughly three hours. It’s the cure for one of the 6.4L’s most common problems-and they sell like hot cakes. Throw in its added coolant capacity, stronger top and bottom core support plates and OEM-style, quick-disconnect connection points, and you’ve got a direct, drop-in radiator that solves a multitude of issues and provides long-term durability. Not only are the end tanks TIG-welded to the core (instead of plastic units crimped onto an aluminum core), but the rubber-fitted mounting pegs relieve the stress that’s placed on the end tanks themselves. With a reputation for offering products that solve both large scale and pesky, common problems on diesel trucks, Mishimoto Automotive designed an all-aluminum replacement radiator for the 6.4L engine. Nearly nine out of every 10 don’t make it past 100,000 miles. If you own a 6.4L Power Stroke and haven’t had to replace the radiator, consider yourself lucky. Be it from chassis flex or poor build quality (there are theories which support both), failed radiators run rampant in these trucks. Case in point, while the 6.4L Power Stroke’s revised head bolt and EGR system ruled out a lot of the blown head gasket issues associated with its predecessor, the infamous 6.0L, the compound turbo’d diesel mill in ’08-’10 Super Dutys quickly became notorious for something else: leaking radiators.
Sometimes even when a “new-and-improved” successor model solves prior issues, it brings with it a new breed of problems. Virtually every vehicle produced comes with its own unique list of quirks, weak links, or catastrophic failure points. Product Spotlight: Mishimoto’s 6.4L Power Stroke Radiator
