I took off my lines from my 95 2wd s10, and I can't figure out which one is in/out. The oil cooler doesn't seem to be marked, but the block is. I replaced the hose like in the sticky so now they can be twisted at the hose clamp and the lines will change where they end up. I have been working on this for hours and nothing seems to fit right, my lines don't have as much flexible hose like the ones in the sticky so its hard to compare. So, anyone know which is IN and OUT , top or bottom on the cooler?
