Question The coolant liquid...

was half a cm above the max.
Today i saw that the level of the liquid is up 3-4cm.
I also saw some spots on the gas tank (maybe the liquid was to hot and came out from the pot.
The strange is that i don't have any problem with the temperature (it goes up to 5 level).
Someone can figure something about that?

Try looking at your radiator cap . They seem to get a build up of silver
stuff on the rubber seal that seems to upset the coolant flowing back
into the radiator when the coolant cools.

Coolant

Radiator cap, air in system - also trying removing restrictive el crappo plastic OEM rad guard - drops temps by about 1 bar or level in any given circumstance - particlulary in slow traffic on warm weather.

Probably nothing serious, just will take a little time and guess work to diagnose, If bike just serviced, dealer might have over-filled or allowed air into system. Gunk on rad cap (I think from anit-corrosion additives) would be easy to check.

Also check specific gravity of coolant - too much coolant vs. water actually makes overheating worse. Water has much, much better heat transfer capability than does coolant. Just has a bad habit of freezing/boiling over. Dang.

Check for black gunk in overflow bottle - if there check with dealer re: water pump. Some earlier 950s had the black plastic pump impeller run against the pump housing - contaminating the coolant and leading sub-par pump operation.

Let us know what you find - others can benefit when they incounter same problem.

If you have a leak between the pump cover and the case, that is an O-ring seal, that tends to go flat after a while, almost looks like it gets enough movement to chage, but either way it flattens out and gets a tad thin. Make sure you get the two o-rings for the pipe that comes off the front of the pump cover, they tend to build up grime, chafe, and distort pretty badly as well. (04 10.5k miles)

Mine needed replacing at about 4500mi. I didn't notice any coolant level change in the radiator or compensation tank though, it just weeped a drop every hour or two.

Guys
I just found this thread. I made a similar post"where does my oil and coolant go"........Anyway I had the exact same problem !! I first tried to add a little silicone to the seal...Still leaked. I then disassembled again and noticed that the housing was poorly made and had some raised areas near the bolt holes.Some filing and sanding later I re-assembled using a liquid gasket compound as well.While seaching this excellent web site I read about elevating the front wheel 50cm or 20 inchs while filling the rad.(oh now thats a handy thing to know,also easy to do ?!) I just parked the 950 on a steep hill which was close enough. Now....no leaks but still using some fluid ?? I'll keep a close eye on it in the next few weeks and post more if anyone is interested.Hope this helps!

My pump has started leaking at 7200 miles. Like you, no increased concumption, just slow dripping. The leak appears to be at the connection to the pipe leading to the radiator, not the pump cover itself, but I may replace both O-rings anyway.

I must confess that a failure like this at such low mileage doesn't give me great confidence. I know it's just an O-ring and they're cheap and easy to replace, but still...it's not like I've been thrashing the bike.

I wouldn't worry too much about it. I've got 9000 miles on my bike now and the ONLY issue it's had was needing that O-ring replaced 6 months ago. My 2002 FZ1 had quite a few more problems in it's 8000 mile stay with me. I really trust my 950.
