Arrows on OEM upper radiator hose

Changed out my OEM radiator for a Koyo OEM replacement and installed new Subaru OEM upper and lower hoses and OEM spring clamps....took 2 hours taking my time. Anyway just realized today that I put the new upper hose on with the arrow pointing towards the block instead of having that end on the radiator. Fits fine. So are the arrows basically to show the direction of flow of coolant? I assume it can install either way?

I'd have to cut it off to remove it as it is really on there, and then get a another one if these are only supposed to go on one way. Obviously I dont mind if I have to. The bottom hose installs with the arrow pointing to the thermostat housing. that one was easy since I left it attached at the radiator end when I removed the radiator. LOL

Edit*

I am somewhat obsessed with keeping things looking as original as possible, I even transfered the rubber seal at the bottom of the original radiator to the Koyo, and I will probably use a heat gun to remove the yellow and silver decals from the original top tank to the Koyo top tank. So even if its OK to install that top hose either way, it will bug me a bit that the arrow on the hose is not on the radiator inlet since it is visible. LOL

So I simply got another one, I didnt want to force off the one I intially installed because these OE hoses fit REALLY tight and it risks damage since they have to be stretched like a basT$##RD to get off.


Also the end of the hose with the arrow pointing to the radiator inlet has a different angle to the bend than the end that goes on the block, so if the hose is installed with the arrow pointing to the block it actually places the hose slightly closer to the power steering pulley. So I DO think that the factory intended the arrow to indicate the flow of coolant as well as a correct position of the hose.
