Vehicles produced from 3/2013 are no longer equipped with an engine coolant thermostat that incorporates the engine coolant temperature sensor (thermostat P/N 11 53 7 647 751). The engine coolant temperature sensor is now an individual component. To accommodate this component change, there was also a production change to the engine wiring harness; this also includes the replacement engine harnesses for earlier produced vehicles. The replacement harness is no longer equipped with the four pin connector for the thermostat / engine coolant temperature sensor, but two separate twopin connectors, one for the coolant thermostat and one for the engine coolant temperature sensor. *The N16 engine switched production to the 11 53 7 534 521 thermostat in 3/2012. This thermostat, like the new 751, incorporates a separate engine coolant temperature sensor. The connectors on the 521 thermostat will not match up to the connectors on a new, replacement engine harness. The 521 thermostat will need to be replaced with the 751 thermostat during this repair.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10149622-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10149622-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10149622","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MINI","model":"CLUBMAN","year_from":2013,"year_to":2014,"match":"exact","vehicle_ids":["2013_mini_clubman","2014_mini_clubman"]},{"make":"MINI","model":"COOPER","year_from":2011,"year_to":2014,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER CLUBMAN","year_from":2011,"year_to":2011,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER COUNTRYMAN","year_from":2011,"year_to":2013,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER COUPE","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_mini_cooper-coupe","2013_mini_cooper-coupe"]},{"make":"MINI","model":"COOPER ROADSTER","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_mini_cooper-roadster","2013_mini_cooper-roadster"]},{"make":"MINI","model":"COOPER S","year_from":2011,"year_to":2014,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER S CLUBMAN","year_from":2011,"year_to":2012,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER S CONVERTIBLE","year_from":2011,"year_to":2012,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER S COUNTRYMAN","year_from":2011,"year_to":2012,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"COOPER S US","year_from":2011,"year_to":2011,"match":null,"vehicle_ids":[]},{"make":"MINI","model":"JOHN COOPER WORKS","year_from":2013,"year_to":2013,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
