COMMON FAULT AREAS ON THE OEM

The Ford 6.4L/6.7L Powerstroke engine is a great workhorse that puts out impressive power numbers and has proven to respond well to modifi cations. Despite the numerous positive attributes surrounding this truck, many owners have found themselves dealing with aggravating and often repeated radiator problems.

TESTIMONIALS

“Got the replacement radiator and installed into truck. Great-looking and performing piece so far. Couldn’t be happier.”

Jim Patterson, Powerstroke.org

“Mishimoto, I have your radiator and I have been extremely satisfied with it. No problems thus far. Please keep us posted on what you find and keep up the good work.“

04hdfatboy, Powerstroke.org

“Love my radiator, and no problems so far.“

CountryAggie, Powerstroke.org

“Mine [OEM] cracked a little over a month ago. Went with an all-aluminum Mishimoto. Can’t beat the price in my opinion. Was only $150 more than a factory Ford radiator, and [the Mishimoto] comes with a lifetime warranty.“

Bigaustin57, Powerstroke.org

“I just installed my new Mishimoto this weekend. Took a good part of the day doing it myself, but it is a super nice unit. Lifetime warranty even if you mess it up in a crash. I kept my stock rad just in case I need to remove the Mish, since the stocker only had a small leak. If you look on xdp.com, they have the Mish rads for a pretty good price and cheaper than a stock one at the dealer.“

Denny diesel, Powerstroke.org

“I ordered my Mishimoto radiator from PTP, and I got it on the exact date that PTP told me I would receive it. To this date I have not had any problems and I love the radiator. The welds are beautiful.“

04hdfatboy, Powerstroke.org

“On average, my coolant temp with the Mishimoto unit is 4–6 degrees COOLER over the stock radiator. In addition to that, the trans runs cooler by roughly 2–3 degrees.“

Buck Russell, Powerstrokearmy.com

“With the Mishimoto unit, my oil stays right around 200–201. In the extreme heat it does get a little warmer, but not by much.

The other thing I noticed, which to me is really important, is how fast the truck cools off after high power pulls. The Mishimoto unit dissipates the heat much better than the stock unit, and thus you can do back-to-back runs or pulls without any cause for concern.

With the stock unit, I noticed that it takes much longer for the temps to be in that comfortable region. Again, another selling point for me, as sometimes I like to give the local Cummins owners a little taste of the good stuff.“

Buck Russell, Powerstrokearmy.com

“I did tow the trailer this weekend and coolant temps were down from the last time I pulled these particular hills. Overall coolant temps were down at least 10 degrees. I will report back when we have a chance to go on a longer trip. This one was pretty short.“

Johnboy3, Powerstrokearmy.com

“I have the mishimoto rad and love it. Very well made piece and performs fl awlessly!“

Buck Russell, Powerstrokearmy.com

“Installed a mishimoto in mine a couple weeks ago no more worrying about the radiator.“

sctreeguy, Powerstrokenation.com

“The Mishi is a well-built unit with very high-quality fit and finish. All the mounting brackets fit “on the money” and it just looks cool. Too bad it is covered up by all the other junk up front.“
