guys thanks for the help the fan worked a treat! i may put in another relay just to hold the temp as you guys seem to be doing this.
but the major issue and it has pi**ed me off royally is that i think i have broke my 335i?
so i was on the way to the leeds festival doing a high revving 70mph when i noticed the water temp go up steadily
major panic and an attempt to get off the motorway asap
i think the needle may have got into the red (? maybe not ?) before i switched the engine off and drove down the exit slip road and tried to stop.
major fear and i opened the bonnet
water pissing out one of the hoses on the thermo

big crack

very hot water spraying out the split
i dont know if i saved it or not but i couldnt bleed it? i had 8 litres of water in the car as i needed it for the festival - incase the beer ran out.
the beer didnt run out so i didnt mind using the water.
so i tried to patch up the rad hose with some electricians tape and then set about bleeding the system ( i hate doing it as i never know if its done right?)
but after a while the water just started shotting out the header tank.
i think there was a air block or something?
so drove I it to a garage that i found and let him take a look.
he tried to bleed it lots but to no avail
i had a 1 hour drive on A and B roads stopping when the temp got up slightly and filling the car with more water.
dont know if the head gasket has gone? i couldnt bleed the thing?
any ideas?
this is the pipe and my fix it job.
notice the tension in my finger
guys will it be the gasket as the reason why i cant bleed it?
oh there is no thermo ion the thermo housing.
