OE 17101438457 — Cowling, Radiator Fan for Bmw

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the cowling, radiator fan should be inspected, and reference 17101438457 replaced if it measures outside specification.

Three checks: the code printed on your old part must read 17101438457; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

A supersession happens when the maker revises a cowling, radiator fan and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 17101438457 we list the current reference; ask our desk for written confirmation before a large order.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

Incoming batches pass a dimensional check, a material look-up against the cooling system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest cooling system reference and narrow by build year. Send photos and we will cross-check the number for you.
