Installation Notes

Verify the hose routing from the heater outlet to the expansion tank before installation. This Rein CHH0150 uses quick connectors and does not include clamps, so reuse or replace related hardware as needed during service. Confirm end diameters and overall routing against the removed part to ensure proper alignment on BMW 323i, 328i, 325i, and 330xi applications.
