I had to reorder 3 times due to a combination of shipping damage and manufacturing defects. One from Amazon, and two directly from Mishimoto. After the third still arrived with the box obviously opened and re-sealed (according to Mishimoto; sometime after leaving the factory), I decided to go forward with the install. Although the radiator is advertised as a direct factory replacement, it had some obvious design issues. There was no bracket to secure the transmission cooler lines to the side of the radiator like the OEM radiator, so I had to cut it off the OEM, modify it to fit, and attach it to the pin bracket on the driver's side of the Mishimoto radiator. Also, several of the bolt posts that are welded onto the tanks of the Mishimoto to accommodate other coolers were too short for the factory bolts and required spacers on the bolts to prevent piercing the tank. All this was reported to Mishimoto who stated they had not heard of these issues before but would pass it on to engineering. I have not filled or run the system under pressure yet. I only hope that I addressed all the short bolt posts. Lastly, the installation instructions from Mishimoto's website appear to be generic for the year range (2003-2007) that my radiator would fit and were not totally accurate or specific to my vehicle (2004 Dodge 3500, 5.9L Cummins HO). At this point, I can't give Mishimoto my recommendations for this application due to all the above. Performance remains to be seen -?
