Coolant leak at block by lower radiator hose

[RckyMtnRider]

I'm just wondering if anyone has experienced this, and what the resolution was. My 99 I/S has a coolant leak on the right side, lower radiator hose, at the pipe connecting to the engine block. Link below has a picture.

I'd appreciate any and all advice.

Thank,

Usually this is the coolant hose.
Over time the hose compresses and loses compression/flex ability.

Snug the clamp and see if that fixes it.

If it is the pipe, I have not seen that before.

Same here.   I'd do what Pete suggests and try tightening the hose clamp and monitoring it.  There's a good chance that may solve it.

That metal pipe is pressed into the block with an O ring inserted first. I's not common but I've heard of the O rings needing to  be replaced. There are 2 of those metal pipes.

I fixed a friend's bike.  Had the same leak. It was the O ring.  Not hard to change, pull the water pipe after draining the coolant. Not bad at all

Thanks for the reply's. Tighting the clamp did not work. I've ordered the pipe. I'll send an update once I get it installed.

Thanks,

You don't need a pipe. Just a new oring. And it's not an ordinary oring it has a special lip molded into it.

So this is interesting. Went on a short ride about 12 miles. The bike has stopped leaking. Just wondering if the pipe may have popped back into place and sealed up. I've ordered the parts, now I'm not sure if I should take all apart. Anybody have any thoughts?

Thanks,

Just to clarify for future reference, are we talking about #11 here: http://www.partzilla.com/parts/search/Honda/Motorcycle/1998/GL1500CT+A/WATER+PUMP/parts.html?

[Chrisj CMA]

Yes #11

I would put the parts on the shelf and wait to see what happens.  These girls spot from time to time. 

Has your bike been parked in the cold and then warmed?  Or vis versa? 

Just keep the coolant level up.

Hook#3287,

The bike is actually new to me. I just purchased it about six weeks ago. I knew the bike was going to need some work. The previous owner laid it down, on the right side, same side as the leak. So I've spent a number hours going through the bike to get it back on the road. This last week I replaced all the coolant and the leak started. It wasn't leaking before. I put about 120 miles on the bike before replacing the coolant.

Thanks,

Jeff

. Congratulations, Valkyries are great bikes.

Seeing you live in Colorado, I thought you're bike might be subject to temperature swings.

It's been noticed that will cause some  seeping, but usually around the pump, at least on mine.

I hate when you do maintenance and it causes issues 

Almost makes you think you should have just left the old coolant in her

I agree with replacing the o-rings.  I also replaced the crossover hose while I was at it.

Can't do it, my computer illiteracy is showing

Old shade tree cure; add 1/2 tsp ground black pepper.

[RckyMtnRider]

I finally received the new pipe and o-ring. Took about an hour to replace. No more leak.

I new about the idea of using pepper to stop a coolant leak. However, I'll wait until I'm on a road trip  to use that solution, should I need it.

Thanks for all the responses,
