right lads tryed geting my car started and worked left it running for a bit 15mins ish and it went rite up to half way, header tank was boiling, steam cumming from the header tank cap and the water pipes from the rad was hot !!!

so turned it off not wanting to do more damage and i could hear bubbling cumming from around the rad and when i could feel the rad top pipe leading to the theromstat it was bubbling still seems to have air in it would this be right ???

also my fan didnt kick in should it have kicked in be4 and would the fan not cummin in before half way effect the water that much it would boil ??
