Minor coolant leak

Postby n5926g » Tue Sep 15, 2015 11:53 am



Afternoon guy,s,
Took the Goldwing for a shakedown run Sunday,and it went fine,parked her in the garage,and looked for any signs of a leak....Yesterday,I got home from work around 5 to find about a teaspoon of coolant under the lh side,pretty much under the shifter...Dried it up,and nothing on the ground this morning when I left...She didnt leak a drop on the drive,or hours after......any idea,s...I had planned to put her clothes on this weekend,but unless I know where this is coming from,I dont want to.....

From what I have read since mine ocasional does the samething is this is normal. It seems like it only happens when there is a big swing in the tempiture from hot to cold. Not freezing just a big change like you get this time of year.

Leaking is not normal. I have owned 3 1500's and the only time I had a leak is when the water pump on my 92 went out. Unless the coolant was just changed and there was some that dripped on the lower cowl you have a problem. Look under the bike, the water is on the left of the oil filter, see if you see any coolant around it.

Have to agree....The bike sat up for about 10 years(at least),and I had drained the original coolant to do the carb swap....I have a suspicion that the water pump may be the culprit,but won,t be able to confirm that till the weekend...I have a borescope with a flexible 3 foot line,so I should be able to actually SEE where its coming from without a lot of dis-mantling....

Had a similar problem on mine, last year. Take a close look at the main hoses that connect to the radiators. There is a known issue where a manufacturing label was left attached to the radiator stubs, that the hoses then attach to and cover. The labels allow the hoses to slip back on the stub, causing a potential leak. I found that very problem on mine. The correct fix is to remove the hoses and remove the labels, then reattaching the hoses to the stubs. I had recently changed my coolant, and took the lazy way out, not wanting to dump the new coolant. I just slipped them back onto the stubs, and tightened the clamps. Haven't had a problem since. It was an intermittent issue, during cooler weather, but the signs of leakage were easy to spot near the point of the leak.

Mine was where the lower hose connects to the radiators.

My such leak turned out to be the water pump went bad and the antifreeze was dripping out the weep hole on the bottom of the water pump. Had to replace and all was well after that. :D :D

ALL good suggestions...Im sure the water pump is original.The ole girl only has 75,000 miles and some change on her,but 25 years old....When I pulled the original carbs,I obviously had to drain the coolant...but it sat dry for about 4 months....never noticed any leaks prior to the carb swap...Got home last night,and 2 drips....Cleaned it up,and nothing this morning....

The plastic sleeves on the radiator pipes were installed on every 1500 from '88 to 2000 to aid in removal of radiator hoses. Radiator hoses can literally weld themselves onto outlets which when trying to remove can damage the fragile radiator or requires cutting of the hose.

The sleeves were designed to be there as an aid to mechanical servicing of the machine although it did not stand the test of time and can cause leakage. Good idea when the bike was on the drawing board in '86 or so.
This is what I do

If that's the case, I'm glad I didn't remove the sleeves from my radiators. It makes sense. I've dealt with radiator hose issues as has been described. In my case, re-positioning the hoses, and re-tightening the hose clamps seems to have done the trick. It's understandable after 15-20 years, that the hose rubber would loose some of its elasticity, causing an 'apparent' looseness.
