Does the cooling system allow the coolent to be drawn back into the system when it is cold, or does the overflow just retain "extra" coolent? I had it out for a good ride today after replacing the two hose clamps on the rubber part in the picture. All seems well. I dont have a way to pressure test it, but I might have a friend at a garage who might have one. Thanks forthe advice!

 

That three way fitting is plastic and with age deteriorates. First sign might seem to just be a leaky joint repaired by tightening the hose clamp. Then it starts again because the fitting has become mushy.

That happened on mine at about 70,000 miles. I suspect it's an age and heat cycle thing, both contributing factors. Hope that helps.

 

Yeah, what everybody else said. Can't be a whole lot of things, really.
+1 on not getting honda o-rings. I bought a set of "universal"AC o-rings for $3 at AutoZoneto fix a leaky injector once. Never gave me another problem. Honda is crazy sometimes.

 

okay this forum is PISSING ME OFF!

I just responded to this thread and it &*#@! up! Grrrrrrrrrr..........

 

What I wanted to say was that it was the rad cap that I believe was leaking. I did replace teh hose clamps....hard to fine canadian made clamps, all they had was "made in China" crap! Whats up with that![:@]

 

I don't know if the overflow is supposed to be drawn back into the system as my bike didn't have a pipe inside the overflow tank. I fitted one anyway. Not given me any trouble & good insurance for $2.00.

 

Good point BB. I'll have to look into that. It makes sense that it should be able to take in coolent as well as expell it.....

 

No pipe in my bottle - system doesn't allow for return as far as I know......?
