I did a cooling system flush etc over the winter , so I know that its clean and coolant mix is correct... I had a zzr that lived on the fan and my gsx1400 was oil cooled with a HEL oil cooler and other upgrades and the fan for the oil cooler would kick in on hot days.just didn't want the fazer boiling up as I had not heard it.cheers for putting my mind at ease.. no doubt somebody will pop along all doom and gloom..
Even on hot days at a standstill in London it doesn't come on, the fzs600 is renowned for having one of the best cooling systems ever!
Never heard mine in 14 years, changed the cooent last year and let is sit running with some flush in and got bored waiting for the fan to come on -- it never did, everything was getting hot making ticking noises as parts started to expand- smelt hot too, I wonder if it even works
Mine started once when I did the carbs sync. It was an hour running at idle and low rpms.
Manual section 8-53, shows connecting the 12V direct to see if it turns......i.e. if it even works - shall see what mine does.... 8-54 also shows them testing the thermo switch by heating it in a bath of coolant....not sure i want to try that!
i can't stop thinking about it now!
So many people saying nope never heard it. Now Im thinking if your fan DOES come on then you have a problem with your engine over heating !
That's what it's there for!
If you're that bothered or paranoid about it, then Radflush your system.
wired mine into a switch so i hear mine quite a lot i will put mine on if im on the track or hooning around in low gears....rather be safe than sorry.
