1988 1500 Goldwing Cooling System

Post by Bluezone » Sat May 08, 2010 9:46 am

What level of effort is there in replacing the radiator hoses on this model Goldwing?

The hoses are original and I have minor leak (I can smell antifreeze, but can't see any) when riding in cool weather until it warms up.

I have successfully done other work on this bike, I changed timing belts ten years ago, should do it again, but the kilometres are low, 85K, but should change belts based on age anyway, and I have a trigger wheel I should put on too. Oh, the fan sensor is also defective meaning I have had to manually turn on the fans for cooling for about 5 years now, so I should get around to changing that as well.

I could get the local shop to do all of this, but so far the only thing a shop has ever done on this bike was to replace the bank angle sensor 15 years ago and this bike has run pretty well flawlessly since I bought it new in '88, and I would rather do the work myself so there is no one else to blame for bad workmanship but me.

Any comments from others that have this bike or who have owned one like it in the past?

A leak that fixes itself when warm could be a radiator - they can develop a pinhole leak, and when it heats up and the metal expands, it closes and seals up the pinhole. You can go ahead and replace the hoses - but I'm willing to bet it won't solve your problem.

If i understand corectly , you seem to have the same problem i have , you can smell collant but can't see any leaks until it gets really warmed up ?
If this is it , mine was the top " Y " hose leaking at the bottom where it connects to the thermostat cover , and its behind the two radiators , not a big job really , i done it myself , hope this helps !!!
Good luck .

If you decide to do it yourself here's a tip.
The upper hose (the Y version) fits on at the bottom where the thermostat is... when you install it it naturally wants to sit off straight. You need to pry on the hose to get it straight and tighten the hose clamp at the same time.

I would also change the belts, even if they haven't done many miles, they are atleast 10 years old and should be changed..

Do you have a part number for the hoses? Is there a way to use a car hose, as there is for the 1100 and 1200?
I'm looking into buying an '88 and will do the belts. Might as well do the hoses as long as I'm in there.
