As above my car has some sort of problem with the coolant.
I opened the bonnet a couple of days ago, only to find there was no coolant at all in the bottle.
I filled up, and started it, and noticed that the pipe that returns water to the bottle was just spitting out water, instead of a constant flow (if that makes sense)
I drove to work etc the next day, got home, opened the bonnet and the water was half way down the bottle! Me and my mate had a look properly and he reckoned there could be a slight leak somewhere or an air lock. So i put some Radweld in and ran the engine.
My mate then suggested running it with the top off while he squeezed the pipes.
This has sorted the flow problem.
Now today i have opened the bonnet to have a look, and the water was down again. I opened the lid and there was shit loads of pressure and the water filled up way over the max line!
I really dont know what is wrong, the temp is normal and never goes over 90 degrees on the gauge.
(Sorry for the essay lol)
