This noise may occur on initial start-up after a cold soak of 6 hours or more that may last for 2-5 seconds. This may be due to an internal component of the variable cam timing (VCT) unit. If diagnostics lead to the VCTs as the source of the noise, refer to the 2024 F-150 Workshop Manual (WSM), Section 303-00 > Diagnosis and Testing > Engine > Pinpoint Test F. Pinpoint test F has been updated to include additional steps along with a video on how to identify the single affected VCT unit that requires replacement.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11024017-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11024017-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11024017","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EDGE","year_from":2019,"year_to":2020,"match":"exact","vehicle_ids":["2019_ford_edge","2020_ford_edge"]},{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2020,"match":"exact","vehicle_ids":["2020_ford_explorer"]},{"make":"FORD","model":"F-150","year_from":2020,"year_to":2020,"match":"exact","vehicle_ids":["2020_ford_f-150"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2020,"match":"exact","vehicle_ids":["2020_lincoln_aviator"]},{"make":"LINCOLN","model":"AVIATOR PHEV","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_lincoln_aviator"]},{"make":"LINCOLN","model":"MKX","year_from":2019,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"LINCOLN","model":"NAUTILUS","year_from":2019,"year_to":2020,"match":"exact","vehicle_ids":["2019_lincoln_nautilus","2020_lincoln_nautilus"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
