The changes are noted in Red text. 01-012/22 10/06/22 DESCRIPTION Some vehicles may exhibit accumulation of dried coolant (1) around the water pipe (2). This is caused by a gap between the housing and pipe due to a press fitting during the manufacturing process. The accumulated coolant is solidified and plugs the gap in high temperature environment and the seepage is stopped and does not progress. This is normal and does not require a part replacement, clean off the dried coolant from around the pipe with a wire brush. REPAIR PROCEDURE 1. Verify the customer concern. 2. If the above condition is experienced, remove the accumulated coolant around the pipe (1) with a wire brush etc. NOTE: Perform the procedure on the vehicle. No need to remove the water pipe and hoses.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036688-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036688-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11036688","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-3","year_from":2016,"year_to":2021,"match":"exact","vehicle_ids":["2016_mazda_cx-3","2017_mazda_cx-3","2018_mazda_cx-3","2019_mazda_cx-3","2020_mazda_cx-3","2021_mazda_cx-3"]},{"make":"MAZDA","model":"CX-30","year_from":2020,"year_to":2023,"match":"exact","vehicle_ids":["2020_mazda_cx-30","2021_mazda_cx-30","2022_mazda_cx-30","2023_mazda_cx-30"]},{"make":"MAZDA","model":"CX-5","year_from":2017,"year_to":2022,"match":"exact","vehicle_ids":["2017_mazda_cx-5","2018_mazda_cx-5","2019_mazda_cx-5","2020_mazda_cx-5","2021_mazda_cx-5","2022_mazda_cx-5"]},{"make":"MAZDA","model":"MAZDA3","year_from":2017,"year_to":2021,"match":"exact","vehicle_ids":["2017_mazda_mazda3","2018_mazda_mazda3","2019_mazda_mazda3","2020_mazda_mazda3","2021_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
