OE 1665000075 — Cooling Water Pipe for Mercedes-Benz

Aftermarket cooling water pipe comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

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 engine & fuel system family — always confirm dimensions and connector layout before you swap.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a cooling water pipe the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 1665000075 with other engine & fuel system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded cooling water pipe transfers stress to neighbouring components, so a small repair can grow into a full engine & fuel system rebuild. Book the replacement once the symptom is repeatable.
