Pressure Test hose caps For 2nd Gen (1993 to 1997) Ford Ranger/Mazda B2000 (1 7/16 or 36mm ID hose)

While I had the radiator out on my 1994 Ford Ranger Splash (Named Madison) I decided to install a block heater since the cooling system was empty. Why not kill two birds with one stone? I wanted a way to test to see if the new block heater was sealing properly before I installed the cooling system, radiator, reservoir, etc. Kits require that the radiator is installed to build pressure. So I came up with this. One goes into one radiator hose, and blocks it off. Use a hose clamp. The other one goes into the other radiator hose and has a schrader valve (Tire valve) (This is the one I used. It's a bit more forgiving. https://www.amazon.com/dp/B0921XYRC9?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 ). The radiator does not need to be installed, and you can use either a little tire pump or a compressor with a tire inflator. Bonus, you can use it the opposite way, and test the radiator for leaks. I do recommend printing it at an angle because compressing the hose clamp could cause the structure to fail if the print lines are parallel to the clamp, same with the valve if printed at 90 Degrees. Ask me how I know.
