Nicely done. Kudos!

[@MurrayEstes]

why?

[@bubbarainman9796]

isnt coolant poisonous?

[@zero187420]

+Bubba Rainman the water never touches the coolant. those lines are sealed from the rest of the radiator, and were ment to cool down AT fluid.

how's it working out? I'm curious if it got hot enough

[@adamdrakemichon]

+why Brass???

[@zero187420]

it gets as hot as the radiator as long as i let it cycle a few minutes. i found out that the tank only supplies enough water to fill the hose so at some point i will put a larger tank somewhere, but thats just hot water, so if you mix it you get more time. Brass doesnt really oxidize and it takes hot temperatures better (honestly no real reason why)
