Upper Radiator Hose, Rein - E39 525i/528i/530i

This part is listed by BMW as BMW part number 11531705223 (11-53-1-705-223) and is described as the Upper Radiator Hose for E39 525i 528i 530i models.

Rubber hoses are ideal when new, as they allow some movement and flexibility during driving. The only problem is that they begin to degrade as they age and can eventually fail. The plastic clips and metal retaining clamps on hoses are stronger than before but they are only really good for one-time use. Once removed they never seem to seal as well, leading to a leak soon after. A new hose is recommended any time the old one is disconnected (unless it's only a couple of years old). We highly recommend that you replace your radiator hoses as a preventative measure before they fail in order to save you from further headaches and expenses.

This is an OEM E39 radiator hose manufactured by Rein Automotive (CRP) - an original supplier to BMW for many components and systems. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
