I installed this along with a lower temperature Mishimoto Thermostat. I tow a 19 foot travel trailer, and have had the engine run hot while climbing to my favorite camping spot. After an afternoon of wrenching, and following the install video from Mishimoto, I had the radiator in. After the install I went back to the camping spot with the same setup. Rather than running 240 degrees I run about 220 in the hardest part of the climb. The transmission runs about 15 degrees cooler (all-around).
