If nothing shows up, run the engine and allow it to get fully up to temp, to see whether heat expels anything. (Cooling engines can actually suck in through leaks .)
Will do. I'll put a cardboard sheet on the plastic under the engine and drive it like that for a few days if it doesn't rain. I think that's the safest bet
Thanks for that info!
I don't have a pressure tester. My mechanic has one, but he's booked for a week so I'll keep trying to find the fault myself. He did say he would take me in if it's necessary, but I don't think it is.

Use toilet roll to check, it finds the smallest of weeps. Just done the rad and condenser on my 407 and there was half a hedge stuck between them, and some feathers. The fitting of AC stops you seeing the front of the rad..If the rad could be the problem, you could remove top and bottom hoses, block them up then use the header tank breather to pressure test in situ, not sure what pressure, but a bike pump with an old tyre valve should do the trick
I'll take that into consideration. That's actually a pretty good idea for testing
