Check if your fan switch has croaked???

The fan seam to be working OK.

thermostate is knackered i'd say.

If the fan is working and making hot air, chances are the rad was too full to begin with. It need expansion room at the top, coolant level just over the coils, or they will expell any excess.

Hope that helps!

The rad was not too full and when i check when i got back to the van there was very little water in. i took the screw out on the side of the barrel and nothing came out.

sounds like no circulation, check the water pump

cheers

hey,

did you ride in map 2?

i know a gasgas will boill over when used hard in the wet weather setting so mayby a sherco does this also?

my 4t (2007) gets verry hot to fan continuesly running than stops for a verry short while (seconds) and that runs again is thins normal?

my cota 4 rt didn' t do this mayby the interval in whith the thermostate switches on/off is to small?

regards bob

Short the fan switch and try it?, see if it overheats then??

Reports?

Take it back to the dealer and get him to sort it he did the pdi.

i tock it back to the dealer he had it for a week, i have now got it back he said he but a new ignition on it, i am not well at moment so i will not get out on it this weekend but one thing that the ignition helped is it was very hard to start when cold but it now starts second or third kick. i have tryed it every day from i got it back and it starts all the time now
