The green slime doesn't look good. Others may correct me here, but I don't think that's normal. I had that exact slime on a set of used NW's intake manifolds that I purchased from another SRT6 owner. Turns out he had an intercooler leak; a known problem with our aging OEM intercoolers. I'm hoping the coolant color you have on your opened up pump is normal. But if it's oily, it may be an issue; hoping I'm wrong.
