⚠ Fitment Notes

The CSF #7089 was designed as a drop-in fit replacement for the BMW OE   17118482623   only. It will NOT replace the OE   17118652497   found on early F3X 340i/440i with build dates up to 07/2016. If you are unsure of which radiator you have, you can visually check (see below) or call a BMW dealership with your VIN to verify.

The CSF #7089 & OE   17118482623   have a single connection on the lower left hand tank for the auxiliary radiators. The OE   17118652497   has two connections for the auxiliary radiators. It may be possible to convert an early model vehicle that came with the OE   17118652497   using the newer coolant line setup, however this has not been verified.
