Guys,

Thats quite strage mate. If it went high and stayed there I would have said the water pump has failed. But correct me if I'm wrong didn't the temp drop again.
I would go with the theremostat is going faulty.

thanks for the feedback guys, yes the temps up and down like a yoyo! - not sure how to right possible air in the system, is this easy? - not sure about thermostat, a fairly cheap part to replace so I'll go with that for now - fans definitely working, most of the time in fact,

take the top rad hose off and fill the block side, then fill the rad side. then put top on back on and top up header tank. trick is to fill VERY slowley to allow it to burp.

thanks guys, I think ive got all the air out the system now, one thing I noticed the bottom (right) rad hose is cold and the top hose (left) is red hot - have I got a knackered rad?
thanks all

The thermostat is at the block end of the bottom hose. Does sound like the thermostat is knackered. Could also be worth reverse flushing the radiator when you replace the thermostat.

How old is the car/rad - did you flush the rad, often a silted up rad will reduce its ability to cool. TBH i would take out the rad and flush it with a hose for 10 or so mins and see what comes out - also change the thermostat.

Olly, if you run it up to temp, does the fan actually work? Would agree with Paul above on flushing the rad.
If you're driving it, I'd expect the temperature to drop as cold air flows through the radiator, the rise when your stationary.
Thermostat is relatively cheap, Mark at Import Car Parts - http://www.importcarparts.co.uk/part...Key=thermostat
Or give Alyn at AS Performance a ring, 0191 410 3770. Alyn will likely have a rad in stock if you need one.
