2014 Cascadia Radiator Part number ???

I have a 2014 freightliner cascadia..I got a radiator part # from freightliner...its 3S0580800001..now Im trying to find the part but cant seem to..I find radiators with a different part # and under the description theres O.E and about 30 other part #s under that...the part # I need is also under there...I asked freightliner if that means its compatible with my part # but basically said probably and ask whoever I buy from..so my question to yall is does that mean that radiator is compatible with my part #? Please no negative comments just need some help...any help would be great!

 

I need the radiator

 

Yes I also saw this..but the number it has there is 0001 and I need 00001...but what your saying is...as long as my number is listed along with the other numbers under OEM then it will work?

 

Thanks for the help! Another ?...how long does it take to put in a radiator and how hard is it? I was told it was somewhat easy not that hard and took like maybe 1-3 hrs...then I heard it was a hard job and that it would take 6-8 hrs...which is true? I heard that you dont have to take the hood off...then I heard you do have to? Ive fixed almost everything else in my tractor..so just trying to see if it can be done myself or take it to shop...
