{"product_id":"aluminum-radiator-expansion-tank-fan","title":"Aluminum Radiator, Expansion Tank, Fan","description":"The Zionsville Autosport Competition Cooling Kit provides an ultimate cooling solution for the BMW E46 3 Series, spanning model years 1999-2005. This comprehensive kit includes an aluminum shroud with an integrated fan, an aluminum expansion tank, and a high-efficiency aluminum radiator. The radiator's construction utilizes PA66 GF30, a glass-reinforced nylon material known for its thermal properties, and UNS A93003 aluminum alloy for superior heat dissipation compared to standard materials.\n\nThe design addresses common failure points in original equipment radiators, such as cracking or brittleness caused by constant temperature cycling in modern BMW engines which can reach operating temperatures around 110° C (230° F). Unlike nylon components, this radiator is built to withstand these conditions without becoming weak, offering a significantly increased lifespan and resistance to impact. It is hand-welded, features an all-alloy repairable construction, and accepts all original equipment components.\n\nThe kit is available with different wiring options for the included 16-inch Spal Electric Fan: No Wiring Kit, Single Speed Kit, or Two Speed Kit, allowing for integration with the factory auxiliary fan control box or a simplified setup. The Block Off Plate can be removed to facilitate the installation of an oil cooler.\n\nThis cooling kit is designed to fit various BMW E46 models including Coupe (2000 323ci, 2001-05 325ci, 2000 328ci, 2001-05 330ci), Convertible (2000 323cic, 2001-02 328cic, 2001-05 330cic), Sedan (1999-00 323i, 2001-05 325i, 2001-05 325xi, 1999-00 328i, 2001-05 330i, 2001-05 330xi), and Touring (2000 323it, 2001-05 325it, 2001-05 325xit) models. Zionsville Autosport offers a lifetime warranty to the original purchaser, requiring proof of BMW coolant use at installation and every two years thereafter. Radiators and shroud kits are built to order, and lead times vary.","brand":"Zionsville Autosport","offers":[{"title":"Default Title","offer_id":52866973630776,"sku":"radiator-type-18","price":1660.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687421834.webp?v=1787909999","url":"https:\/\/store.motormia.co\/products\/aluminum-radiator-expansion-tank-fan","provider":"MOTORMIA","version":"1.0","type":"link"}
