Coolant line splice

Post by Zman457 »



Hey all,
I'm changing timing belts on my 96 GL1500. Bike has 24k miles. Original owner said nothing has been done to the bike. Well, someone has replaced both lower sections of the small coolant lines that run in front of the timing cover. The replaced line is braided and a tad bit thicker. They used plastic hose barbs, and yes the plastic was brittle. Is it ok to use a barb made of another material? I'm thinking brass would be a better choice than the plastic.

Thanks, Eric

Brass would be better.
However, better still is to just replace those lines so there are no splices in them. Any splice will be a restriction and a place for gunk to collect, possibly blocking flow.

I'll have to take a look and see where they go.
That would definitely be a better option as long as they aren't a huge hassle to get to.
Thanks

It's a GoldWing, pretty much everything is a huge hassle to get to. Comes with the territory. :D

There's almost as much stuff packed under the tupperware of these bikes as you'd find under the hood of a Honda Car. Gonna be tight!

A really good fitting for splicing is 1" pex brass fittings - you can get them at Menards. I use these on all my conversions as the fit perfect and lock in nicely. I have a hose expander which helps with the install but normally a little grease will help ease them on. about $5 each

Never thought about pex fittings. I didn't feel ambitious enough to remove the entire line. They were spliced together where they were because the previous repair person didn't want to dig them out either :lol:
Thanks
