Or like me, he just loves tools and gadgets in general. But, it is nice when you need a left handed hammer you can reach up on the board and grab one.I take it, you aspire to be a ase tech someday that you need alll this stuff
Reusing old spring clamps will bite you in the ass sooner, or later. I always replace them with new ones.
A litle thing called physics requires that fluids move from an area of higher pressure to one of lower pressure. So the inlet has to be higher than the outlet. How much depends on what the pressure loss across the radiator is.top ones reused on my rig are ok after almost 4 years... no leaks no seepage
but i will monitor that bottom one reused for any pink seepage at the lower radiator outlet because U got me all worry wart now
is the pressure out at the bottom more than the pressure into the radiator at the top
