Pushing Coolant, Checked the usual suspects

[nismo521]

On the way home from work this morning, I saw some steam coming out from behind my right headlight housing. I limped it home (2 blocks) and popped the hood and it was pushing coolant out of the overflow. Checked the rad cap, it was fine. No oil in the coolant and no coolant in the oil. Any ideas?

Air in the system? Try using the bleeder screw to get any air out. I remember my KA being tough to get all of the air out.

Well, I found it. Hairline crack in the pass. side of the top tank, right next to the top hose. So, w/ the replacement I'm wanting to go all-aluminum, any one know anything about the CSF radiators?
