Right so those of you who've ventured to the cooling systems thread will have worked out the rather hilarious yet sad situation I found myself in over the past 2 weeks.
I bought a $20 temp sensor off eBay to replace the stock one. Bled the car like 7 or 8 times all resulting in overheat on the guage. Turns out sensor was ****ed as the second I put the stock one back in we were smooth sailing again. It did cause mass frustration and I did purchase a neat bleeding set up for my aftermarket radiator:



Got the idea off Robk and now its spill free. Before I had to unscrew plug then screw it back in with coolant going everywhere. Now I have a 70cm coolant hose thats permanently attached to radiator and hides under garnish. When bleeding I take hose, take cap off, attach inspection hose and when coolant is at the right level I bring hose down to that level take inspection hose off and cap it off. It's a brilliant system.
While I was waiting for coolant to settle I put some stickers on:
Got all my coolant together for a laugh:
And found some toblerones:
