Right lads, here is the story...
Driving along the road noticed the temp gauge going past half way so stopped and then tried letting the motor cool down.
Got the car back home but had to cruise at 30 and it was still overheating.
Started the car a couple days later to try to figure out what it was. The coolant was bubbling and temp was rising, so cut the engine off.
I tried the engine again but this time I had changed the thermostat, fan switch and also tried the fan directly off the battery to make sure the fan worked. The engine overheated again with coolant boiling, no heat comes out fans in car and idles at 2000rpm... Pretty strange. Also I tried my mates radiator cap and it still does it!!!
So I then changed the head gasket, got a second cylinder head pressure tested, skimmed and valves changed. Got everything back together and still the temp gauge started increasing past half way so had to cut it out just to protect everything. The car still idles at 2000rpm and sometimes jumps up and down between 1500rpm and 2000rpm. There is no heat either out the heater still so I am stumped...
Can anyone give me any ideas??
I think I have noticed the fan doesn't seem to kick in though, I don't know if a relay is goosed but would that cause all the problems?
Cheers!
