Technical background To heat the engine as quickly as possible during cold starting, delivery of coolant from the coolant pump is interrupted in the warm-up phase by the solenoid valve for the mechanical coolant pump. The solenoid is designed to cut off the vacuum supply to the coolant pump when the engine reaches the maximum temperature, the vacuum cut off allows the engine to start circulating coolant by retracting a sleeve which is situated around the coolant pump impeller. When the solenoid is at fault (sticking open) the vacuum supply is constant, this allows the sleeve to stay in position around the impellor which leads to the symptoms described within the Customer statement/Workshop findings section of this TPI","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201957-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10201957-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10201957","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"BENTLEY","model":"CONTINENTAL GT","year_from":2018,"year_to":2022,"match":"base","vehicle_ids":["2018_bentley_continental","2019_bentley_continental","2020_bentley_continental","2021_bentley_continental","2022_bentley_continental"]},{"make":"BENTLEY","model":"CONTINENTAL GT CABRIO","year_from":2018,"year_to":2022,"match":"base","vehicle_ids":["2018_bentley_continental","2019_bentley_continental","2020_bentley_continental","2021_bentley_continental","2022_bentley_continental"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
