We are the SS vendor who developed and sells the Paradox By Design Cooling System Upgrade kits. There are 50+ members on here with HMMWVs and CUCVs and civilian 6.2/6.5 trucks as well running our kits. The system does not reduce the overall system temperatures much at all as mentioned but you will see less temperature buildup. The overflow issues you are having are likely due to the aeration of the coolant from your water pump cavitating at higher RPMs. Then the rear of the block holding on to the air due to the lack of proper flow, causing steam pockets and localized super heating until the system 'burps' the air and you lose coolant out of the cap. Our system is constantly bleeding the system as you drive. We have even had a situation where a friend installed our kit into a truck with a blown head gasket before he knew about it, then without other good options was able to drive 500 miles home without overheating because the combustion gases were being bled off with our kit. We have a blog article on our website that goes into great detail why our kits work. Take a look.
