well put the new cooler on last friday and woke up and went to the con for a day trip. i ran from my house to loon basically to stop for gas but straight there. i will tell you no over heating was happening. Awesome right that is basic alt two hours most of it climbing. and the cooler is not as big as i thought it was i wanted a bigger one. ran all day, to little sluice and back out and all the way home...... although i was so worried about my tranny fluid that i forgot about motor oil. luckily there where some fine yota owners that helped a brother out. thanks to all for the info and knowledge.
