• Fitment issues on BMW lower coolant hose applications without quick-connect fittings

Installation Notes and Tips

Verify hose routing, end diameters, and the absence of quick-connect fittings before installation. Compare the molded shape to the original hose to confirm correct orientation on the BMW 320i, 325i, 325xi, 330i, and related lower hose applications. Inspect adjoining clamps, necks, and coolant passages for wear or residue before refilling the system.
