Direct replacement radiator engineered for the 328D diesel—core and tanks built to handle sustained cooling loads. Designed as a like-for-like swap for models equipped without transmission oil cooling integration. Factory-spec aluminum construction handles daily driving and highway miles without compromise.
Will this radiator fit my 328D if the original had a transmission cooler?
No. This radiator is designed for vehicles that never had transmission oil cooling built into the radiator. Check your original part to confirm whether it has transmission cooler tubes before ordering.
Do I need to drain coolant before swapping this in?
Yes. Drain your cooling system completely, disconnect the upper and lower hoses, and remove the mounting brackets at the factory attachment points. Reverse the process to install. Refill with the correct coolant type and bleed air from the system afterward.
Does this come with new hoses and clamps?
Radiator assembly only. Reuse your existing hoses and clamps if they're in good condition, or source replacements separately. Inspect rubber for cracks or hardening before reinstalling.
