Lower Radiator Hose with Sensor, Rein - E46 M3

This Lower Radiator Hose is a stock replacement for your E46 M3's S54 cooling system. The temp sensor located in the lower hose is also included (it's a common source of coolant leaks).

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, leaving you with the potential for loss of control from coolant spilling and/or an overheating situation.

Replace your E46 M3 lower radiator hoses as a preventative measure before it fails, and save yourself from further headaches and expenses.

This is a radiator hose manufactured by Rein (CRP) Automotive - the original supplier to BMW for this part, as well as many other hoses. As the 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.
