OE 17137516004 — Radiator Cap for Bmw

OE 17137516004 is the factory reference for this radiator cap on selected Bmw models. The Applications table on this page lists the confirmed rows — check trim level and build year against your own fleet before ordering, because one reference can cover several body variants.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the cooling system family — always confirm dimensions and connector layout before you swap.

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.

KingMay supplies OEM-grade aftermarket parts built to the 17137516004 factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.

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.
