Constant Coolant Top up Needed - Why?

[tkroukamp]

Thanks all for your comments. I'm adding about a pint of coolant every 100 miles or so, and that's definitely more than 3 quarts over the last six months.

I was afraid of the possibility of a piece of the impeller causing problems in the system. I'm going to look into that a bit more.

I will also try burping the system.

If I don't get anywhere, I'll just suck it up and take it to one of the mechanics in the Atlanta area that has been recommended elsewhere on this site, rather than the one down the road that don't impress me that much.

Thanks again!
Tony
