Hello everyone, I'm iin the middle of changing the water pump on a 2002 X5 4.4 that I purchase for $1500 the other day.

I have the water pump off, so now I'm ordering the parts that i need to replace.

The smaller lower hose that goes from the water pump and connects to a black platic box on the lower passenger side of the radiator needs to be changed but i don't know what part number or the name of this hose.

I tried doing a seach on Ebay but it's hard to tell from the pictures.

Does anyone on here know?

Thank you in advanced.
