Intermittent coolant leak

[PeteB]

Well, I'm definitely in the "work the bugs out" phase of the build. I went to a car show tonight and when I pulled one of the coolant lines was leaking just behind the right front tire. I couldn't see exactly where it was coming from with out jacking the car up, so I let it cool down, enjoyed the show, and called my wife to bring some water and follow me home. Got home, pulled into the garage, and no leak. Not even a drop. WTH? :shrug:

Obviously I need to take a few long drives before the 4.5 hour trek to Kentucky in Sep for LS Fest.

Are you sure it was coolant and not water that had collected somewhere in the bodywork?

No, it was green and smelled like antifreeze.

Coolant leaks usually are more common as a hot engine cools down. Try pressure testing the system after warmed up to locate the leak. It may need to cool down quite a bit until you see something. Also there are ultraviolet dyes you can add and trace with a black light if it's difficult to pinpoint in a hard to see area.

Are you using silicone hoses Pete? If so....constant tension hose clamps work best.

Ken, my hoses are rubber.

I put tighten the clamps on the holes I think was leaking. I guess I'll just watch it and see if it happens again.
