Have you had this problem?
 

Has anyone else had a problem with their radiator overflow bottle? The hose on the bottom of mine seems to come off or loose at least once a month. Nothing in particular to cause it but it does drip on my floor from time to time to warn me. Is there any easy fix I can do to prevent this from happening?

No I've never had the problem but can you put a clamp on it. truthfully I've never really had to look at it.

I think I am just going to deal with sliding it back on occasionally until I need to replace the CCTs then while I have everything off I will hose clamp the pesky little bugger. I know this is kind of off topic but how long do the CCTs last and how will I know when they need to be replaced?

There will be a distinct rattling noise coming from either (or both) side of you. I'm not sure how long the OEM ones last, but some owners take the initiative to replace the OEM ones with manual verions as preventive maintenance.
