Right, after putting my engine back in, my rad fan dosnt seem to be working, after i had just been running the engine for a while, realised it wasnt working when the needle went into the red, i left the engine running opened the bonnet, having a look at the electrical connection between the fan and the wires, fine looked up and
PISHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
something of the header tank came off and i got absalutly soaked in boiling dirty engine water, now i am completly soaked, have a burnt face and have a broken fan 
what else could cause it to do that, i do notice i have a spare connecter coming off my starter motor loom bit, i will take a pic once my car and me have cooled down!!!

there is a plug on the fan but thats the main feed.
there is a temp controlled switch in the bottom left hand corner of the rad which cuts the fan in at a certain temp

I'm havin same prob with mine atm. Get the end of the connector that goes into the switch on the rad, put a piece of wire across the two metal contacts inside it, then turn your ignition on. If the fan fires up, it's the switch that fucked. If the fan doesn't come on, then its either the motor or the wiring loom thats up the spout.

best to do it with it off so air can escape. there is no actuall way of bleeding them really. make sure you have the heater to hot.

whenever I've drained my rad, ive given the pipes a good squeezing, you'll see water gushing back into header tank when you do it... that should in theory force any air out of the system.
Works for me.

best way to bleed system is leaving it ticking over with heaters on full and hot and the header cap off
