2009 MV Agusta Brutale 989R
Coolant change Brutale 989R
I am one of the worst “mechanic” ever but maybe you can help me. I wanna change the coolant in my Brutale 989R 2009. In photo number one I have place where I put the new coolant but I lost everything via this stub pipe. Where should I put this stub pipe?

I think that is the drain hose for the coolant expansion tank (photo 1).
It allows coolant to escape to ground when the radiator cap releases pressure (photo 1) ....most frequently from an overfilled system.

I used to be fast....now I just dream about it.

MIN is plenty 'nuff
Welcome to the MV coolant lore.
You check the level when cold.
Look for the level and notch in the plastic coolant tank on the LH side.
Pour coolant.
If 1L is missing bad news.
Fill'er up to the MIN mark
Any coolant above the MIN notch will spit out the overflow tube.
On your picture the tank is way over filled!

You must use a funnel with a narrow tip, so that the end is passed the overflow outlet.
If you haven’t done it already, there are workshop manuals available for download via Donsy’s website that explain in more detail. Use the search function.

Thank you so much. To be honest a cut the bottle and I use it as a tip. Tomorrow I will buy sth better.
Is it only one place, this tank where I should put the coolant or we have sth more? In some bikes you have two places.

If you added coolant to the expansion tank while the existing coolant was present then that added amount will exit via the drain tube. Fluid in, fluid out. Should you wish to drain the entire system, flush with distilled water and refill with new coolant. Use the coolant drain plug. If you are topping off then it looks like you did that job a little too well. I would remove some of the overfill with a siphon.

I have one more question. Becasue someone told me that I have to fill up also the radiator. I remove and put back the alloy pipe. Is is true or still I have to fill up the coolant only in this one place?
