boiling over

[Valley boi]

Started the bike this morn (fzs 600) and left it for  a while and the fan didn't kik in and it started spewing water out. How  do you check if everything is working. The fuse is ok .........cheers

[anutz]

what do you mean it started spewing water out?

If you want to check the fan you can short a certain wire to ground.....it was posted a while back - will see if i can find it......

but whats is spewing out....and from where....its not coolant is it leaking from some where...

[Punkstig]

From the overflow pipe or somewhere else?

You have gunged up waterways, get down to Halfrauds and buy some Radflush.
Empty your coolant then add the Radflush and water and take it for a ten mile spin, but don't go nuts as you don't want the bike to overheat.
Then empty the system, flush with a hosepipe, and refill with decent coolant and all will be well for a good couple of years.

Decent coolant/antifreeze is as important as the correct oil, don't go and buy some nasty old shit down Lidl's, you wanna preferably buy motorcycle coolant.
I use this stuff which is excellent but i doubt you'll find it on the shelf on the quick.

There are two temperature sensors attached to the thermostat block under the tank. The one with the brown and blue wires is the thermal switch for the fan, short those two together (NOT to earth) and the fan should run.  If it doesn't you've a wiring or fan motor problem.
If it does then the fault is either the switch itself or the water isn't getting circulated.
