Replacement Radiator - Cooling for BMW E46 6-Cylinder — Overview
This is a stock-style replacement radiator for E46 6-cylinder cars, including 320, 323, 325, and 330 models, plus Z4 applications using the same basic cooling layout. It lines up with OEM replacement use, not an oversized performance setup, so it makes sense when your original radiator is seeping at the end tanks or just getting brittle with age. If you are fixing a daily driver or refreshing a tired cooling system on a street car, this is the kind of part you buy to get back to baseline.
On E46s, radiators are usually not the only failure point, so I would not throw one in without looking hard at the expansion tank, upper and lower hoses, and the coolant level sensor seal while you are there. Pick this over a used OEM radiator every time, but if you track the car or run sustained high temps, I would look at a full cooling refresh and possibly a higher-capacity setup instead. Fitment matters on these cars, especially around transmission type and hose connections, so double-check your original part number before ordering.
