Coolant leak

Post by g1djh10 » Sat Mar 06, 2010 1:30 pm

I just noticed a puddle of antifreeze under my 2003 GL1800. It's been stored in the garage under it's cover and on the battery tender since late November. It's just a small puddle but puzzling. This is the 1st winter I've had this cycle [only 9700 miles on it] and I don't know if this is normal. Any thoughts, comments or ideas? It's still too early to get the cycle out [salt, snow and cold] but not too early to start worrying about it...

Well any fluid leaking out of your bike isn't "normal." That said, cold weather can cause seals to shrink, allowing fluids to leak. I wouldn't start really worrying about it until you take the bike out for the summer. Top up all the fluids, and keep an eye on it closely. If it continues to leak, then do something about it. If no leaks - then don't worry - at least until next winter. :)

I had a similar leak on my 2003 1800. I'd read on another forum about loose hose clamps etc. I took my bike to a reputable mechanic and they had to pull the top cover and gas tank to get to the leak. I had corrosion around the thermostat housing and several loose clamps. Not a big deal for them to fix but they popped me for 5 hours labor at $72 per hour.It hasn't leaked a drop on the ground since.
