The hose is designed around the original routing and connection points used on the transmission oil cooler to heat exchanger line, helping preserve factory-style fitment on BMW 230i, 330i, 430i, and 530i applications. Rein’s OE replacement approach focuses on matching the original hose geometry and connector style rather than adapting a universal design.\u003c\/p\u003e\u003cp\u003eThis part cross-references BMW 17127640287 for the same application. If you are replacing a leaking or deteriorated hose on a BMW 230i, 330i, 430i, or 530i, CHE0848 provides a direct-fit service part for the cooling circuit connection.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCoolant seepage at the transmission oil cooler to heat exchanger hose\u003c\/li\u003e\n\u003cli\u003eCracking or hardening of the original BMW hose\u003c\/li\u003e\n\u003cli\u003eLoss of proper hose sealing at the connection points\u003c\/li\u003e\n\u003cli\u003eCooling system service needs on high-mileage BMW vehicles\u003c\/li\u003e\n\u003cli\u003eFitment issues caused by using an incorrect replacement hose\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify the hose end diameters and routing before installation.
