Expansion tank cap broken

[BarryM]

This is my first post on behalf of my son who has recently become the owner of a 2007 Ford Focus, great car and he's very happy with it but I thought I'd check the usual fluids etc before he heads back to Uni.

The coolant was about an inch below the min line so decided to top it up but the cap has unscrewed leaving what looks like the middle pressure valve bit still in the expansion tank top. I haven't tried too hard to get the middle part out yet as it seemed quite tight and after ***** the main cap back on all seems water tight.

I didn't find anything when i searched on this forum but googling it brings up a few similar results for Fords so have we just been unlucky or is this a known issue?

I believe it's an issue some people have. I have smeared a very tiny amount of silicone around the threads to prevent it "seizing" in the bottle.
