Coolant leak

I just purchased a 2001 GL1800 that has been sitting for a 1 1/2 years. The PO claims it was fine when he parked it but when we started it and it ran a bit a decent stream of coolant was coming out in the middle of the bike just behind the kickstand. Any ideas? What all do I need to remove to find the leak? Bought it at a decent price but it may not have been the deal I thought it was!

If you can't see where it's coming from by looking around under the bike and around the alternator, then you will have to remove the shelter, seat, and gas tank to get to the top rear of the engine where the water pump is. There's also hoses and clamped fittings that could be the source on the top, rear of the engine. There is a weep hole in the water pump, but you will need to drop the recovery tank down to see it. It's tough to get a good look at it, but is doable.

I haven't looked under it. I'll get it jacked up and take a peek.

Do you think that I can get a better look if I remove the alternator? The leak is not a drip but more like a small stream. It starts leaking after the bike runs for about a minute. Hoping it is a hose clamp or something easy.

Yes, you can see the water pump, but you won't be able to see the hoses and their clamps.

How many miles on the bike ? Most likely it needs some hose clamps tightening, but it could also be the water pump leaking, either way you might as well remove the gas tank to check it out, the first time removing the tank seems like a pretty big job but once you have done it it's not really that difficult. If your going to do your own work I recommend getting a set of Fred Harmon's videos.

Thanks. I'm pretty handy. I have a Handylift and a place to work on it. I'll tear into it!

Hopefully the rodents have not chewed the pipes while stored.

That's a thought, especially on the top of the engine, quiet, dark, and a tasty treat just inside a little rubber.
