If the cooling system becomes contaminated with ATF, the system must be flushed clear of the contamination after the source of the contamination has been repaired. It is generally not necessary to replace the following components due to ATF contamination in the cooling system: radiator, heater core, de-gas bottle, water pump, auxiliary water pump, coolant control valves, temperature sensors, thermostat, turbocharger, heat exchangers, tubes, gaskets/O-rings/seals (unless removed), or rubber coolant hoses (unless swollen).","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10218605-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10218605-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10218605","components":[{"id":"engine","name":"Engine","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"automatic-transmission","name":"Automatic transmission","parent":"powertrain"}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2022,"match":"exact","vehicle_ids":["2020_ford_explorer","2021_ford_explorer","2022_ford_explorer"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2022,"match":"exact","vehicle_ids":["2020_lincoln_aviator","2021_lincoln_aviator","2022_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
