Review on Mishimoto MMRAD-WRA-87 Performance Aluminum Radiator for Jeep Wrangler YJ/TJ 1997-2006: Enhance Cooling Efficiency and Performance by Carlos Reyes

I bought this radiator to replace my stock radiator which has served my 2004 Jeep Wrangler faithfully since it was factory installed. I was very excited at the prospect of this TIG welded all aluminum heatsink with rubber insulators. When it arrived, everything screamed quality, right down to the perfect welds. After only a few months of sporadic use, a small leak started above the passenger side drain plug where the air foil meets the lower reservoir. A large constant flow of coolant flowed from the site throughout the week. I'm going to try to get it replaced under warranty now, but it looks like my heatsink came without the serial number plate attached. Overall I was very impressed at first but after only a few months I'm very concerned about the quality control of this product. In anticipation of a replacement I will update my review. Updated February 2021: Working with the warranty department was quick and easy. However, the replacement radiator started leaking again in the same place a few months later. I will contact the warranty department again but I may end up buying a replacement MOPAR. The first radiator served from 2004 to 2020.
