That just left a couple of minor issues to address. The first is that the radiator is actually just a bit lower than the thermostat housing. To solve the filling problem that creates I’ll be using an in hose fill neck in the upper radiator hose. The other problem is that it’s almost impossible to remove the radiator cap on the radiator without loosening the radiator supports, and I really don’t want to cut a section completely out of the upper support. I decided to put a 16 pound lever cap on the radiator and I’ll use the nipple on that radiator neck for the overflow bottle. The lever will let me relieve pressure on the cooling system if I need to. I’ll use a 20 pound cap on the in-line filler and plug the overflow port which will basically just limit that cap to being a fill for the cooling system.
