boy Mississippi, you're really testing my memory banks....all things are metric on the GL1500 ( although they were built in Ohio)...the ID (Inside Diameter) of the hose needs to be checked at the Autozone ( 8mm is close to 5/16", 6mm is close to 1/4"...many hose manufactures have switched over to metric, but a few Autozones still carry English fractional sizes...for us old guys working on old cars) ...if memory is correct ( ? ) you'll need a 6mm (ID) hose ( 1/4" is a little too big)...strongly suggest you take the carb set (or just the heat plate) to the Autozone and make sure you have the correct size....a suggestion: if it's available is to use a hose made from silicone ( its a high dollar option)...they're usually orange in color and can handle the heat that is generated down in the engine room ( I purchase my silicone hose from NAPA)...check also the clamps that you're reusing or replacing...make sure they will fit the OD ( outside diameter) of the hose you purchase...hope this helps

You have a 1990 Wing, which is similar to my 1991.

The right coolant line is a custom pre-molded hose that is still available from Mother Honda. It connects to a temp sensor under the right manifold. I suggest you get this hose from Honda. Good luck installing this one - there are (2) stays under the right manifold that you will need to open up to replace this hose, not to mention that the connection to the temp sensor.

The left coolant line is a short 1-2" piece of hose that connects to a T. You could use a aftermarket hose for this one.

The right side coolant hose looks like a pita to me. Here's a pic of what the hose and routing look like.

Spiralout, your coolant pipe image is for the 1992 and later Wings - not for the 1990 and 1991 Wings. In 1990 and 1991, no hoses went to the water pump. One did go to the right radiator, however.

You are right about one thing, though - it will be tough to replace the right side hose. I am thinking intake manifold removal.

Yep, correct. I pulled that pic from my later year FSM. I posted it mainly to show the shape of the right hose and how it goes down to the thermal valve. The shape of the left hose is different in my pic too. Later years have that curved piece that slips on a nipple on the large hose and like you said, his has the short hose that connects to a tee.

Ya know..those hoses look like they are in excellent shape to me......I have a bedroom full of "clean" parts,and a garage full of "to be cleaned" parts....Running out of space.......Thinking seriously about putting some new clamps on them,and "letting it bump"......

I am just curious - does your significant other mind that your bedroom is full of motorcycle stuff? I have some parts on my kitchen table right now and my wife is all over me. I would be sleeping at a hotel if I attempted to use my bedroom for Wing parts! :lol:

Actually she is quite the "trooper"...As long as everything is CLEAN,its ok...we have 5 bedrooms in the home,and the "Goldwing room" is the smallest...She lets me wash parts in the Laundry room sink......I have a double garage,and a single...the Honda lives in the single side...Back when we had the plane,she let me keep Cessna parts inside too!!!!!!...:-) ;)
