{"product_id":"coolant-expansion-tank-12","title":"Coolant Expansion Tank","description":"The MTC coolant expansion tank serves as a critical component for your BMW's cooling system, offering a reliable solution for replacing aged or leaking original units. By providing the proper space for coolant to expand and contract during heat cycles, this reservoir helps prevent cooling system failure and maintains optimal operating temperatures.\n\nThis replacement part is designed for compatibility with various BMW E46 models, including the 323Ci, 323i, 325Ci, 325i, 325xi, 328Ci, and 328i, as well as select E83 X3 and E53 X5 3.0L models. Please note that the expansion tank typically does not include the cap or coolant, which may be required for a complete system refresh. As with most cooling system maintenance, it is recommended to inspect surrounding components such as radiator hoses and sensors during installation to ensure the entire system functions correctly.","brand":"MTC","offers":[{"title":"Default Title","offer_id":52689298948408,"sku":"17117573781","price":47.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687513671.jpg?v=1784904786","url":"https:\/\/store.motormia.co\/products\/coolant-expansion-tank-12","provider":"MOTORMIA","version":"1.0","type":"link"}
