Drivin' my '66 Chevy . . . and I get a coolant leak ! What the hell? A cracked hose? Nope. Where's it coming from? My water outlet was so corroded under the hose, it was spitting out. The coolant corrosion resembled trails army ants leave in wood. Nothing lasts forever. My friend Jim still had the 230cu in straight six he pulled from his Biscayne back in high school (1977) out in the grove, so he stole the outlet off it for me. It was almost perfect condition. I'll be running again soon !
