Quick question re: radiator hose and aux fan assy

[Gen X5R]

Greetings Forum,

I just received my 2003 X5 4.6is from it's second round of repairs in as many months last week with the aux fan assembly being one of the repairs done. I have driven the car less than 100 miles since picking it up and on the way home yesterday noticed steam coming from the engine. Luckily I was less than a mile away and when I popped the hood, I noticed that what appears to be the upper radiator hose had come detached from the radiator housing. Is it a coincidence that this occured or would this hose have been removed as part of the auxilary fan assembly repair and then improperly reinstalled. Any quick responses are appreciated as I am ready to have the car towed in and would like to be able to speak as intelligently as possible as to what's going on. (This forum is making me a smarter X5 owner...fer sure!!)

Thanks in advance for the responses!!

That hose is shot bro, it's not supposed to separate at the band, the upper radiator hose is a unit with three hoses attached to it. Click on the link below, it's part #1 in diagram, I replaced all of the cooling hoses and expansion tank on my 2002 4.6is last month, you are advised to do the same. And no you can't replace one hose at a time on these damn cars, it will put pressure on the older hoses and they will blow on after the other, ask how me and lots of others on this site know...lol!! I see you only have two posts, so obviously your new, use the search function and do some reading, again trust me, replace all the hoses, not just one!
