While filling up my coolant from the engine head and engine expansion tank, I realized the radiator expansion tank fills up and overflooded on the ground.
I scratched my head and it made sense, cuz the top of my VR6 engine is about 6" above the radiator.
I have an expansion tank close to the engine, it uses the highest head hose and tees it from the top into the top nipple of the expansion tank. No fluid will go there by gravity.
Do I really need the radiator expansion tank? If not, what do I do with the rad fill cap, I simply block the nipple and if there's too much pressure it will push all the way to the top hose of the head and into the engine expansion tank? Or I need to route a hose from the fill cap nipple and tee it to my engine expansion tank?
If I do need the tank, uh, how on earth can I design that setup...
Did you use the rad expansion tank and if yes for what purpose? How is your coolant system setup compares to mine I just described?
