When my 2001 r6 gets up to temp, the fuse pops for the fan, i changed the fan and still does it. i tested the thermo switch and thats good. any ideas???

you changed the thermo switch and relays and it didnt fix it
did you test the fan motor itself

the fuse box cover should have a fuse layout diagram
engine cooling fan

look for a 30 amp fuse

they usually near the fan relays

is the air con cooling fan working with air con on
and engine running

Check the relay for your thermo fan, should be in the main fuse box under the bonnet. Often when they heat up the fault presents itself. Other than that your thermo fan might be faulty.

CHECK TO SEE IF POWER GOING TO COOLANT FAN AND COOLANT FAN THERMO SWITCH.THERMO SWITCH LOCATED BOTTOM OF RADIATOR ON THE LEFT HAND SIDE.IF POWER GOING TO THERMO SWITCH THEN SWITCH IS FAULTY.IF NO POWER GOING TO THERMO SWITCH OR COOLING FAN.CHECK LARGE FAN FUSE IN THE ENGINE COMPARTMENT AND YOU HAVE FUSE 16 IN FUSE HOLDER.IF FUSES GOOD YOU HAVE SHORT IN THE FAN WIRE OR FAULTY FAN CONTROL MODULE.SHAKE FAN WIRES IF FAN WORKS PROBLEM IN THE FAN WIRES YOU HAVE A SHORT IN THE WIRES..

if your cooling fan is not switching on then i would check fuses then if all fuses are good check for 12V at you cooling fan when temp gets between half and 3/4 way to hot . if you have no voltage it could be a temp sensor or relay . if you have voltage there your fan motor has gone bad and needs to be replaced . another thing to check is the hoses running to the radiator . let the bike idle and warm up and check the temp of the radiator hoses . if one is much cooler than it should be then you might have a bad thermostat on your bike and its not opening enough to let coolant flow at idle. water pump could be going bad as well. if the bike warms up and fan does not kick on untill you rev it up a bit i would check the thermostat and waterpump

change thermostat? does it run thermo fans ? make sure they are connected, if it has thermo fans change the temp. sensor

replace coolant sensor connector?if so can u get a thermo lazer gun to check the block temp? this will tell u if the gauge is incorect,,,go ahead a bleed all the air out of cooling system and see if that does the trick

it could be a few different things, first thing i would check is the fuse, if the fuse is ok, unplug the fan and jump it stright from the battary to make sure your fan is still ok. if the fan dont turn stright from the battary then replace the fan. if it does turn ok then you have a thermo switch that sences heat and tells the fan to kick on, what you need to do to check this switch is, unplug the switch, take a peice of wire maybe about 4 to 6 inches long, strip both ends and connect them to the leads inside the plug.. kinda like direct connect, turn on the ignition and see if the fan turns.. if not, replace the thermo switch. the only other possibility is in the cooling system wireing witch i dont know much about.. i just went threw the same thing with my 2001 yamaha r6 and i changed the fan and it was still popping fuses when the fan was supposed to come on. After 2 days of checking and trying i made the descovery that a wire harness was hitting the fan blade causing it not to turn.. i hope this helps you out and good luck..

Check your ground wires, that can cause a fuse to blow..Make sure the replacement fuse is same amperage as the original....the fan on this is only supposed to run at low traffic speeds right? you shouldn't need it at highway speeds.. Good luck to you friend....Tim
