This radiator was installed on a 2006 Toyota Tundra double cab 4.7 V8. I've done the same ride in Southern Utah for the last 5 years and in front of this cooler, when I was towing a 4500 lb trailer with a flatbed truck loaded right to the limit of my GCVWR, my transmission hit 220ยฐ in minutes , as I drove past Soldier Summit UT. Highway 6. This year I rode this route again, a little harder, and the same passage, the gearbox turned 194ยฐ. This is definitely a good investment. Smooth driving onโฆ
