Show original supplier description

The Zionsville Autosport BMW E46 Aluminum Radiator is engineered as a direct replacement for the factory plastic unit, designed to fit all non-M Series E46 3 Series models, whether automatic or manual. This construction offers better heat dissipation than standard nylon radiators, which can degrade and crack under the high operating temperatures (around 110° C or 230° F) common in modern BMW engines. The radiator is hand-welded with an all-alloy construction, avoiding epoxy, and has been tested at 4X operating pressure. All original equipment accessories will mount to the new unit without modification. This radiator is backed by a lifetime warranty for the original purchaser, provided proof of BMW coolant use at installation and every two years thereafter. It is made in the USA with Euro Aluminum Cores. Fitment includes a wide range of E46 models: 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).
