Coolant issues

Ok so I have a 18 plate f3 800rc, I have only ridden it a handful of times with no issues so far.

Today I rode around 27 miles to work in good traffic conditions and good weather conditions, when I got to my work place, the bike had leaked quite a bit of coolant, have been told it could be the garage overfilling the reservoir and the bike just getting rid of the excess.

The temp gauge was not indicating and issue either so I went with this explanation, on returning home from work the same thing happened only this time I could actually hear what sounded very much like boiling liquid coming from a small reservoir tucked into the fairing...

That can't be normal, can it!!? Please help any thoughts on this welcome.

I believe that the coolant level should only touch the bottom of the LOW LEVEL indicator on the header tank, when cold. If it is above that level, I believe it will do as you descibed.

As XPARAUK said, dont overfill the coolant reservoir.
Place it directly onto the MIN level line and not any higher. (Left side it is shown)

When the bike gets to operating temperature and you get to a stand still in traffic it rises to about 3/4th of the reservoir.
Fill it any higher than MIN level and it will spill coolant.

Not sure if your dealer has filled it all the way to the top. They should know better!
Or if you yourself "topped" it off.

Now you know though

On another note, aside from the good advice above, there could be a problem with your pressure cap. If you are hearing the sound of boiling, then the system is not staying at a sufficient pressure to stop that vaporization. Boiling cannot occur below 212*F or 100*C as a norm unless one is significantly above sea level.

Your coolant system will have temperatures above that in normal conditions which is why a pressure cap is used.

Pull your pressure cap, clean and inspect the contact surfaces and then reinstall the cap. If your dealer recently serviced your bike as indicated, then the cap could be loose, dirty, or corroded.

Once that is verified, we can move on to more obtuse possibilities.

Did your dealer do a coolant change, or just top it off?

Ahh thanks very much for the advice, I didn't buy it from a MV dealership, it was a bike showroom, they may have gave it a service and thought it was low so topped it up. I will also inspect the pressure cap thank you all so much for your advice.

So would you say the bike is ok to keep riding and it will get rid of the excess coolant over time on it own. Confused as to why it hasn't done this from day from day one but I guess it's been pretty warm here lately.

F3 RC800 Love the red wheels Very sharp looking bike AND a very capable bike. Many people make the mistake of thinking MV AGUSTA motorcycles are all style and no substance . I have shocked many R1, GSXR, CBR1000RR and ZX10RR owner/riders with my F4RR/ F4RC spec MV AGUSTA racing them on twisty roads. FYI my riding skills have gone to shit. My lower spine is shot to hell so its the bikes superior handling not my skills as a rider .

BTW .I upgraded the OEM water pump to the racing water pump and IMHO its well worth the 400$ Also installed the silicon hoses but I do not think it improves in engine cooling Silicon hoses just look cool.lol

Unless your hearing boiling sounds, it would appear it's the normal MV cooling system ooeratiin., So should be safe to ride.

Where are you based? General form is to add your bikes and location either in the signature and profile.

Depends on the bike! The F3 waterpump is integrated with the oil pump and the common advice from the F4 forums to replace/ upgrade the water pump doesn't apply here.

I live in Hampshire in the UK, and I have been hearing a boiling sound from a plastic reservoir by the handle bars. Think I will book her in for a service and get it checked out.

Thank you all.
