I just got around to dumping my coolant in my sprint st, the stuff that came out was this god awful brown stuff, has anyone else experienced this? Also I went to take out the bleed screw at the top but it seemed to click click click almost as if it was stripping in the plastic so I didn't keep turning it . Is this absolutely necessary? . I'll flush it all out next weekend and go from there...

Sounds like oil in the coolant...Does it have kinda a brown milky look to it. If so, this is not a good thing.

Lets not talk him into something here. My coolant is also brown bu the bike has been recently service by a Triumph dealer. Could well depend on the colour of the antifreeze.

I didn't know that coolants came in colours other than green!

Fluorescent purple would be nice, along with transparent engine covers to see it flowing and glowing :-D

I would suspect rust is the culprit. If the bleed screw is indeed striped, this could be the source of air entering your cooling system accelerating the rust.

Its been a while since Ive looked at the bleed screw arrangement, but if I remember correctly you have a threaded brass insert in the plastic. I have sucessfully repaired these in the past with a little epoxy and patience.

Good luck.

I too had this problem with my coolant. It was quite bad, and it took the mechanic quite awhile to get clear running water through the system.

I have heard the 955 uses wet steel liners and they form part of the waterjacket. So, if the coolant is too diluted or mostly water, then rust will form, and voila, brown coolant.

***** messy stuff. Good luck getting yours sorted out.

I think it's the first time it's been changed, I only got it last year, I'll do a good flush this weekend coming, has anyone used rad flush I'm worried about it being too corrosive maybe I'll stick with straight water. There isn't a skim of oil on the top of the coolant I took out so I think it is just rust. Not sure how I'll repair the bleeder screw maybe some epoxy if I can get it out. I'll check and see what the stealer wants for a new piece........After seeing my coolant my advice to anyone is change it religiously every 2 years!
