Original BMW Radiator Coolant Hose for BMW 228i xDrive, 328i, 328i GT xDrive, and 428i (2012–2016)

Coolant moves to and from the cooling system components of the N20 and N26 engines through this Original BMW radiator coolant hose, built for the BMW 228i xDrive, 328i, 328i GT xDrive, and 428i (2012–2016). BMW names it simply a coolant hose and sells it by the piece, at 545 g (1.2 lb). Production started in July 2012, and BMW's parts data shows no end date for this number. Over time a radiator hose can turn dry, hard, or brittle, or begin to leak, and any of those conditions is the point to fit a new one. Every radiator hose is one link in a sealed coolant circuit, so a single weak hose puts the whole system at risk of losing coolant.

Original BMW Parts carry a 24-month parts warranty.

BMW applies this hose to five chassis, beginning with the F22 2 Series, where it fits the 228i xDrive. In the 3 Series it covers the F30 and the facelifted F30 along with the F34 Gran Turismo, and in the 4 Series it covers the F32 and the F36 Gran Coupe. Across the 3 Series and 4 Series, rear-wheel-drive and xDrive versions share the same number, so drivetrain does not change the part. Shops often call it a radiator hose, while BMW's own description is coolant hose, and either term leads to this same part.
