Thanks for the advice.. I have a spare header cap so might drill the center of it out.. rubber grommet and funnel.. and burp it.. hopefully that will sort it! Will keep you posted

Yes.. thermostat would be my next port of call.. for the sake of a few quid I'll replace it for piece of mind.. people have mentioned there is a high flow stat available which works better. Unfortunately I can't get one today as nowhere is open

Checked the hose to expansion tank.. all good there.. what's the most effective way of making sure it's got no air locks??

Hi guys.. I'm new to this forum and haven't got the foggiest idea how it all works so please excuse me.. i need to pick your brains.. ive got a 51 wrx wagon, I had a new radiator fitted a month ago as the previous had split.. everything has been fine.. until yesterday when I was driving home i noticed it starting to overheat.. I had nowhere to pull over so switched the heaters on full and it settled again.. managed to get home etc.. opened the header tank this morning it was vacuumed sealed and "popped" off with a pull.. it was half full so I've topped it up again.. run engine with cap off squeezing hoses to remove air etc.. but it feels like the time hose has minimal water through it.. any ideas?? Thanks in advance
