Any ideas on Leaking Coolant

mpgscott · Feb 14, 2010

Well went out today and ran the bike for the first time in weeks and noticed that i had coolant leaking out of one of jubilee clips on the offside feed to the radiator. Now the radiator has been swapped out and when i did this i changed from the ****** snap on clips Ape use for simple standard jubilee jobbies! Since swapping over i have covered around 1000miles and the jubilee's had never leaked before, so i am just scratching the head as to why it would suddenly fail now after sitting idle for some time..

Any ideas??

I have since checked it all and the clip is fine i have simply re-fitted and tightened and ran the bike upto temp and no more leaks. I am just wanting to find out why it would be fine for a 1K miles of running (back in Sept) then once parked up for a few months it decides to start leaking on running upto temp, anyone else experienced anything like this??

:cheers

May be talking out my arse here

MAybe in the cold the rad metal contracts more than the jubilee clip metal.

I've had the same. After a few months of sitting idle it was weeping a bit when warming up. I tightened up and had no problems running it since.

the standard clips are *****. I don't reckon reckon much to the rubber ducting either (maybe why there's a few aftermarket kits about).

I don't think it's anything to stress about mind, just keep an eye on it for a while

Not a good anti freeze mix ??? Crap stuff not doing its job. ??? Cold,,, EXTRA cold weather we've had. :dunno:dunno:dunno

Cheers guys, no its a good mix with proper Ape approved coolant and its mixed as per the manual suggests. Think its just Weeksy and Rusty suggest i will just keep an eye on it, good that others have seen the same thing.

Hopefully the bloody weather will improve so as i can get out on the bugger. Was going to go out yesterday after the footy but when i pulled off the main road and was on the back roads the amount of **** in the middle of the road its just not worth the hassle or mess on the bike.

Roll on good weather.

Again cheers for the thoughts:thumbup:thumbup:thumbup

Mine was doing the same last year so I bought proper jub' clips and it was fine after that.
I reckoned it was the blob on the side of the alloy tube thats preventing a proper seal. Could be wrong tho.

I've only got out for two short-ish runs this year and I noticed a couple of days ago that it's back. So I'll nip them up and see if that's all it was.

Suppose it's another Italian build quality quirk they call charcter!

coolant with antifreeze added is more viscous than plain water...it will seep through openings where ever there's a nano-gap, whilst water won't. it could simply be that you didn't tighten the clips enough to begin with.

you mentioned you'd swapped out the clips for some decent ones ( 8mm stainless ??) but did you remember to check the clips on the thermostat housing also...
