My Metro has developed a small coolant leak. It has never lost a drop of coolant since I bought it in 2001, but I took it in for a rebuild a few months ago and since then I've lost a couple cups worth of coolant. Dollars to donuts that they didn't quite put on the new head gasket properly. No puddles on the ground or noticeable white smoke. I don't relish the thought of trying to convince the dealer they messed up, so I'd like to fix it myself if possible.
I bought some Bars stop leak, but I also noticed there was sodium silicate "liquid glass" at the store too. Heard a lot of good about Bars, but the other one is a mystery to me. Did a search and couldn't find much. The silicate one is more expensive and requires flushing out the old coolant and letting the silicate sit 12 hours before driving. Fine with me if it'll do a better job than Bars, but that's the question, will it? I use traditional green coolant so you'd think there'd be plenty of silicate floating in there already, though it may not be the same stuff, not too sure on that.
