Well it was a hot day however the gauge went up the fan cut in the gauge went down, all good, a few miles later the gauge went off the scale and the red light was going bonkers, pulled in to a service station to cool down ( got a puncture in the process) lots of steam from the tank at the back but once it had cooled off there was no loss of water from said tank. A couple of miles more same thing happened.No heat from heaters (headgasket?) Got a tow home from a mate. the engine would run on tickover without any obvious problems at the temp gauge but as soon as any load or revs applied up went the needle again. Left it for a couple of days went to start it, now it wont fire up and i have white smoke coming from the vents (crewcab by the way)
This sounds expensive doesnt it

I know nothing about science so i hope someone here can suggest what the problem may be .
Thanks
