Right, think I've got an airlock after replacing one of the pipes 2 weeks ago.

I bled the system but only from the rad, and ran the engine with the header cap off until the fan kicked in. I then topped up, tightened the bleed screw and fitted the header cap.

Positive I've got an airlock though as when I undid the cap last night the level went upto the top! Laughing

Do I need to bleed from the back of the block as well? If so what's the best way to get to it and should I do that before the rad?

Cheers guys.

Do you mean when you undid the cap the level then rose? Was the engine still hot?

Cold engine. There was a release of pressure and the level rose. Then there was also air in the rad. :?
