Did the water pump not fail? Did the system have enough coolant in it as well?
If the pump fails the engine will heat up very quickly, even going along at 70mph, but then gauge would probably still show cold as I think the sensor is in the top of the rad.
possibly a blockage? Some crud in the coolant system broke off and blocked an engine passage. No cool water in, but heat still coming out?Or on oil passage blockage leading to seizure?
if the fans is melted perhaps it failed altogether. could be atleast partly to blame
Thermostat might be stuck shut, not opening and letting the hot water circulate, or a blockage somewhere.
A common problem on some cars is that the impeller in the water pump is plastic pressed onto a steel shaft and comes loose. Any restriction in the cooling system is going to increase the resistance on the impeller making it start to slip. Once it starts slipping it will heat the plastic very quickly and soon the shaft is spinning but the pump is doing nothing. If that is the case, you only need to flush the cooling system and fit a new pump.If it's the same as something else of course......
If you had a blockage or clogged up waterways then the coolant would've overheated, got pushed into the expansion tank then it would boil like a kettle and get dumped on the floor if it couldn't circulate properly.Then when the bike cools down any remaining fluid would get sucked back into the main system, leaving you with a very low or empty expansion tank.I've actually watched it do this on my previous bike.That's why it's always worth the occasional quick shake of the bike on the centre stand to check the coolant level is where it should be, 'cos it's a very good indicator if the system's in good shape or not.If all is well the levels should pretty much stay the same when the bike is cold, other than a very minor top up every few months if at all needed.
why dont you just flush the entire system take out you thermostat incase that was the problem to begin with?...then try running it again just on water and see what happens ....test the thermostat seperatly in a saucepan of hot water up to boiling point and see if it opens and try to record the temp at opening use a temp probe ....my jag years ago did same thing when it overheated due to thermostat jamming shut?...and i got that burning smell like you describe!!
Did you put the coolant in yourself, or was it there from the previous owner?If there was more water than coolant then the fluid would boil like kettle water, as coolant/antifreeze raises the boiling point, as well as lowering the freezing point.
All I did was clean some of the gunk out of the header and top it up with distilled water.

I suspect a blockage, The header had some mysterious, thick red goo at the bottom of it that came out neon pink after being mixed with distilled water . I suspect the rad and pipes are similarly clogged.Seizure, I doubt, as the bike still starts cold, and has run fine up to 3/4s temperature (hotter than it ever used to, admittedly), with no funny noises.
