where could the leak be? Has about 100,000 miles

Locate the water pump. It has a pully on it. It's not uncommon for Honda water pumps to go at 100K if nothings ever been done in 11 years.Consider having the timing belt changed if that's never been done and have the water pump replaced while it's off.Your Accords not even half done, so the repair will be worth it.

Probably the radiator. Take it to a shop and they can pressure test it to see where it sprays out. Costs maybe 20 bucks, and then youll know for sure.

Your leak could be arround the top or bottom hose or near one of the 2 top brakets that hold it in place. Honda radiators are very fragile and are prone to carck easily. I've had to replace one on 3 of the many hondas i've owned. Even cracked one installing it and its only 2 hoses, 4 bolts, and it slides down in with ease. The guy above has the right idea about the preassure test and a radiator will cost you at the most $120 unless you upgrade to an aftermarket part.

It is definitely your radiator. The water pump is located inside the timing cover and any leaks there would not show up at the bottom of the radiator. Depending on where you live, the radiator has a very limited life since any road salt, rocks, debris, and temperature differences wreak havoc on the thin metal fins that make up the bulk of the radiator. My bet is that your fins are turning to dust and are causing minor leaks resulting in pooling of coolant. Before long, and I actually mean very soon, those weeping leaks will turn into an outright failure and you will lose engine coolant. Probably somewhere you really don't want to stop at! With the loss of coolant comes the loss of engine cooling and your engine life could be seriously jeopordized.Honda radiators aren't really even bolted in... they sit on big rubber grommets on the bottom (one each side) and two more on the top. Before you even start to remove it, check out how much it moves right now. You will find it has quite a bit of freedom sitting in there! The only bolts are those attaching the fan(s) shroud(s). One if you don't have AC and two if you do. These shrouds bolt directly to the radiator. Two hose connections is all that remains to get the thing out. Actually, I think you can remove a crossmember (with the hood latch attached) and the radiator lifts out relatively easy.I just put a lifetime warranted radiator in my '90 Prelude to the tune of $180 but I waited until it blew up and was forced into a quick fix. I am finding radiators on Ebay for $100 or less.Check this out:http://cgi.ebay.com/ebaymotors/Honda...2922QQrdZ1Good luck!

may be the side split open on the radiator...or another seam at the top...my 96 Accord had the same problem last fall
