Small coolant hoses

Post by khspe2 » Sat Mar 28, 2015 2:59 pm

I have a 1991 GL1500SE and I would like to replace the small coolant hoses. I have (2) questions:

1. Does anybody have experience replacing all of these hoses? I have removed all of the Tupperware except the fairing, radiators, fans and carbs and it still seems like access is going to be tough without removing more (intake manifolds etc).

2. Mother Honda has discontinued some of these specially molded hoses. I have contemplated purchasing 5/16 premolded coolant hoses and cutting/modifying them, but it would be trial and error trying to get the right hose (assuming that even that hose is available). I could also try to modify/use a coolant hose for a newer GL1500, since the coolant hose routing changed after 1991.

Any suggestions would greatly appreciated.

I haven't...mine are still in good shape, and I'm hoping they remain that way for the forseeable future, as it's a bit of a nightmare getting to all of them.

If you do go ahead with this project, take lots of pictures for us, as I'm sure there are lots of people who would be interested in the process.

Replace all the hoses, no way, just the ones leaking.

Use bulk silicone hose for the obsoletes as it takes to curves easier.

I was in the same dilemma of how far I should go with the coolant hoses. It appears that to do all of them, it would be a major undertaking of removing the carb's, manifold, etc. I understand the o rings can be a culprit too. I think I was fortunate enough that I replaced one spring clamp that was loose that was connected to the thermostat. Had to remove the radiators though to get to it. I ended up cutting the crossover tube on top of the radiators that connect to each other since it was next to impossible to remove. I found that the 5/16" hose worked perfectly. They do have a much large OD as compared to the stock, but no issues. Good Luck
