| SYMPTOMS | Common indicators of a failing or leaking pump include low‑coolant warnings, visible coolant seepage around the pump or bracket, dried coolant residue, overheating or temperature warnings, and bearing/whine noises that vary with engine speed. |
| TROUBLESHOOTING | If leaks persist after replacement, inspect the bracket‑to‑block gasket surface and fasteners, and check for hairline cracks at hose quick‑connects. Confirm vacuum supply to the pump actuator (no leaks, proper operation). A thermostat or hose fault can mimic pump issues; pressure‑test the cooling system and inspect for coolant traces at the pump weep area and bracket seam. |
| INSTALLATION | This OE assembly includes the pulley and a vacuum‑actuated control mechanism. Replace associated gasket/seal; ensure alignment dowels seat fully and torque fasteners to spec. On some B48 variants the bracket‑to‑block joint may use an RTV or a separate gasket—inspect and reseal/replace as required. Verify the small vacuum line to the actuator is intact and connected. Refill with BMW‑approved coolant and bleed per BMW procedure or with a vacuum fill tool. |
