Cooling System Woes

[Dual-500]

What engine is in it? I have one I could probably be talked out of for a "D" series.

I would guess the o-ring at the pump intake is the problem. Most likely somewhere in the tube - could be a small coolant line to intake FITV or EACV/IACV depending upon what's on your engine.

If it's been a while, and you have the free labor, replacing pump and timing belt is a dandy idea - do the idler pulley too.

Don't get under it when hot.

pretty sure he has an ls b18b in there

Yup. B18B. It needs a little TLC right now, but I've personally put over 120k on it. ~188k total. A few bucks to keep it running well over 200k is worth it.
