Alright, I hauled gravel for 4 hours this weekend. Something I forgot earlier, I am only hauling about 1/2 mile through the fields to our road, so only using 1st and 2nd and letting it idle while loading. I yanked the stat, I was wrong it was a 160 and i had drilled a burp hole. With it out the truck didn't heat up as bad but each load I still had to spray the botton of the rad down and add 1/2 gallon of water. The temp gauge never got above 190 doing this and upon the cool down would go down to 100 until I got to the river.
Once finished I tried to reflush the motor, water comes out clear as can be. The petcock shot out some brown and then went straight to clear. I left the top hose off and cranked the truck and it about pumped the rad dry before I could jump back out the truck, so I have flow. I think I am gonna make a fan shroud next.
