Before beginning work on the vehicle open a TIPS case and request the tool you will need. In your request include a contact name, phone number, and shipping address for the tool to be sent. Before the tool arrives: Remove and replace the coolant expansion tank (reservoir) and the main radiator. Without removing the components: flush the heater core and changeover valve (located in the right front wheel arch) in the opposite direction of flow until no debris remains. Once the tool arrives, proceed with flushing the vehicle per the instructions attached in this LI. A picture of the filter after each flush must be taken. If after the prescribed number of flushing attempts debris is still being collected in the filter, upload all the pictures to the TIPS case and wait for next steps.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10253772-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10253772-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10253772","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG C43","year_from":2023,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG C63 S E","year_from":2024,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA45","year_from":2019,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA45","year_from":2021,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLC43","year_from":2023,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG SL43","year_from":2023,"year_to":2024,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
