Original BMW Radiator-to-Engine Coolant Hose for BMW 2 Series Gran Coupe and X2 (2018–2024)

Coolant travels between the radiator and the engine through this Original BMW radiator hose on the BMW 2 Series Gran Coupe and X2 from 2018–2024. BMW calls it the radiator-to-engine hose. Radiator hoses carry coolant to and from the cooling system components, so a failed hose leaves the engine short of coolant. This one is made in the Czech Republic and sold as a single hose.

A 24-month parts warranty covers Original BMW Parts like this hose.

BMW put this number into production in July 2017 and shows no earlier part number that it replaces. The same hose is used across two chassis and two engine families in this fitment, the F44 2 Series Gran Coupe and the F39 X2, with the B46 engine in the 228i Gran Coupe models and the B48 in the M235i xDrive Gran Coupe. On the X2, BMW's data matches it to the B46-powered X2 28i and 28i xDrive and the B48-powered X2 M35i.

Common Questions

What are the signs this hose needs replacing?
Cracking, leaking, swelling, and general deterioration are the common failure signs. With age the rubber can also turn dry, hard, or brittle, which warrants a new hose.

Should the coolant be changed when this hose is replaced?
Yes. A coolant flush and fresh coolant at the time of replacement clears out any sludge that has formed in the system over time.
