Well finally have the thermostat cover and gasket!
So now got to dig out my insulated coveralls and start crawling around.
Plan to change out the parts then run it up to temp for a while to dry off the motor then let it sit for a week and examine the situation,, will update.

I'm not comfortable saying I resolved my issue yet, but it's been over a week now and no more drips. The white rag under the bike is spot free. I took a driver to all the accessible hose clamp. There were quite a few that were at lease two turns loose. I never actually saw coolant dripping or any visible markings where it might have dripped. The bike is still all over the garage. I had it down to the carbs, but not out. Waiting for the new E4 tires to arrive. I've been wrenching down all nuts, bolts and screws I can find. The header bolts were quite loose. I wonder if tightening them will change things?

New 90amp alternator
New Gel Cell battery
new cruise and sub filters
new speakers
changed almost all dash and radio lights to LED
new descant in the air pump
rebuilt the air shock (seal & oil)
put a USB powerport in the left cubby
new Honda driving lights
repainted the lower under-panels and front cowl with rock guard
rebuilt the forks w/progressive springs & new seals
new front wheel bearings

I been busy. It keeps me from pining about the cold and snow keeping me from riding.

Well the drops of coolant are back. This is getting frustrating. I think I'm going to have to put fluorescent die in the coolant to find this weeping coolant. After a few weeks there were two drops on an old t-shirt I put under the bike. They're very small drops but they are happening, and from somewhere I can't see. I have a sickening feeling it's up under the carbs.

Has anyone here used dye with our Goldwing? I don't want to put any fluids into the bike and cause another issue. I see Amazon has GM branded dye and there's a lot of other dye's from several companies. I know we can't put certain coolants into our Goldwing, so I use Honda brand coolant. This is my concern with the dye. I don't want to damage the system, so I'm hoping someone has history using a certain brand with success.

Hey that sucks Mark.
Once I received the parts the weather has turned too cold to work in the space that I have so I still don't know if I have my problem solved either.
I hope someone has used the dye as that may be my next step too.

My '81 GS 850 Suzi has never given me any cooling system problems in the 20 plus years I've been riding it! ,,,,,,

I picked up a cheap Chinese borescope to have a look into the guts of the problem. I found quite a number of drippers under the thermostat housing so I removed the plastic, AGAIN!

I intend to remove the fans and radiators to replace the thermostat and its seal. I picked up a couple of o-rings for the front pipes. I'll check the o-rings on the large pipes that go into the t'stat-housing but I don't think I need them. When viewed with the borescope it looks dry around the large pipes. I'm optimistic. It does look very cruddy under the t'stat housing though, like it's been leaking coolant and drying up for a while. I had to clean crud off the scope lens a few times while poking around under it.

I have a new upper radiator/fill hose. The lower looks good. I may just remove it for inspection and go from there as it doesn't leak. I will replace the upper equalizer hose, too.

I've looked at dozens of forum posts regarding coolant leaks on this and other boards. Some have said this is a normal occurrence when wings get really cold but I've never had any vehicle drip coolant that wasn't a problem, so I've got to try and solve this coolant dilemma. Whether it's hot or cold out, I want it dry.

More to come...

So today I started after the thermostat cover. Got the right side rad mostly out, still one hose top inside attached.
Removed the stat cover clamp,,, the clamp was barely contacting the hose,,, took a pic and went in the house!

I ended up cutting the crossover hose to get the rad's out. It was crispy anyway. Man are things tight in mine. What did you do to overcome the rubber heat shield in yours? I don't see it. Mine is totally in the way to the point I'm not sure I can work around it. At least I believe the stat housing seal isn't the problem. I do believe it's an o-ring issue. I have no desire to remove the carbs and it seems like that's the only way to get at them.




At best it appears the plug wires will have to be moved and that 3/4" hose behind the stat housing is inhibiting me from removing the bolt. I did move it enough to verify I could loosen all three housing bolts, so they aren't frozen as I feared. This also let me know the t-stat seal isn't compromised. That's what leads me to think it's an o-ring somewhere. I cleaned it all up with brake cleaner so I flushed all evidence of leakage tracks away (doh...) but I'm certain it's on the left side as the right side was dry and free from crud.

My wife came out to see what I was doing and she suggested I listen to everyone who said it's a cold weather thing. She may be on to something as I stand back and ponder my next move. At 65 my dexterity and stamina isn't what it use to be. Suffice to say, I slept well last night after crawling around on the floor all afternoon into the evening to get to this point. This is a BIG and dirty job. You just can't get all the coolant out of the system until you start to tear into it. Even after studying all the schematics I wasn't prepared for all the hoses I found inside and how tight they're placed together. Doing the timing belt was a cake walk compared to this task. Even taking the upper fairing apart to change to LED's in the dash did nothing to prepare me for this.

Sounds like your having second thoughts about the importance of a few drips of antifreeze on the ground that only happens in colder weather and disappears after warm up. I went through the same scenario. I ended up with both radiators out and the carbs off. I ended up replacing the thermostat and gasket, a couple o rings, hoses, clamps and the rubber mat. The mat was an even bigger pain than the thermostat. No leaks now but I am still wondering if it was all worth it. Be prepared to be there a while. :(

There's a small puddle of antifreeze under my bike right now. But as long as that only happens in cold weather when bike isn't running I'm going to continue to call that "Not a Problem", and just top off the reservoir when "regular riding season" begins. There's enough warm days here in Winter I don't "Winterize" 'cause I might be out riding on one of those 65* January days...

But if I start seeing drips or steam AFTER one of those January rides or find myself adding coolant in the Summertime I'm likely to change my mind and declare it a "problem". :shock: Long may it stay Wintertime Drips ONLY. :lol: :lol:

Yup. You are correct. But what I absolutely can not stand is the acrid smell of evaporating antifreeze and the steam rising up the fork tunnel, settling on the windshield and gage cover. If this doesn't go away when it warms up I'm likely to take it to someone to get fixed.

I have the o-rings for the two front pipes, but those back pipes that connect to the housing/heads I'm not too sure of and they may be "the ones". Definitely not pulling the carbs. The bike runs like a champ so I'm not breaking what isn't broken.

By what I see on my bike, you must have pulled your carbs? Or is there some trick I haven't discovered yet. I preordered the thermostat and seal, so if there's another way to get that back bolt off and the housing up far enough to get the seal and t-stat in I MIGHT try. My bike is a 1994 Aspincade. Not sure if mine has more hoses and pipes than some of the pictures I've seen of other bikes, but it sure looks like it does.

How important is that mat/heat shield, anyway? If I remove it there's no way I could replace it without removing the carbs.

Otherwise I think I'm changing the two front o-rings, the upper crossover hose, cleaning up and sealing the radiator hose connections and calling it a day. Twenty years ago I wouldn't have given it a second thought, but these days arthritis has the best of me. My brain is more than willing. In my mind I'm in my 30's, but the body has limits. Ah, such is life.

I should've explained a little better in my last post. I was a little upset that the stat housing clamp had such poor contact with the hose because I think it was bad enough to leak. So, do I reassemble and test?
Mark, yes the cover is still there just pushed back.

This aft I went back out to reexamine the hose and its clamped location. I concluded that I needed to reinstall it properly along with the other undone connections, refill the system and heat cycle the motor which I will do tomorrow.
I need to know to what extent it may have been the problem or part of.

Concerning the rubber mat/heat shield,it’s pretty necessary. It gets very hot in that area and the mat keeps excessive heat away from the ignition wiring, among other things. There are discussions on this forum explaining it better than I could.

I presumed so. If it's there it has a purpose. During a brief moment of desperation I considered removing it but I know I wouldn't be able to get it back in place. :mrgreen:

The mat also helps keep fuel from boiling inside the Carbs on hot days... Very important. :D :D

As suggested I did a search on the topic. Lots of info on the subject.

Suffice to say, It needs to be there.

Mine(the mat) came out in pieces. It’s next to impossible to replace it without removing the carbs. And even then it’s a bear. They aren’t cheap either. Over $60 when I bought mine a few years ago for a piece of what looks and feels like rubber roofing.
