Installation Notes and Tips

Verify connector style, hose size, and port layout before installation. The CP487 uses a female rectangular connector, male blade terminals, and a single-port configuration, so matching the original part layout is important for proper installation on the Cadillac CTS. Inspect vacuum hoses and EVAP lines for cracks or soft spots during replacement to help prevent repeat faults.
