Description
BMW OEM coolant expansion tank and radiator cap 1742232, supplied here as a used and tested original part. Web verification supports this number as a 1.4 bar coolant tank cap used on BMW applications, with sources matching the part function as an expansion tank or radiator cap. The title also references BMW chassis families E30, E34, E36, E39, and E46, so those chassis codes are preserved only as listing identifiers from the original title rather than expanded into unverified fitment claims. This component is intended for the cooling system and serves as the sealing pressure cap for the expansion tank or coolant reservoir. As a used OEM part, it is suitable for buyers seeking the original BMW numbered component instead of an unnumbered replacement. The listing is focused on the exact OEM identifier and the verified part type only: 1742232 coolant expansion tank cap, 1.4 bar. Please match the number on your existing part and review your vehicle documentation or parts catalogue before purchase, especially where BMW supersessions or alternative cap numbers may exist across different cooling system versions.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
