OE 2742003000 — Belt Tensioner for Hyundai

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.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded belt tensioner transfers stress to neighbouring components, so a small repair can grow into a full transmission & drivetrain rebuild. Book the replacement once the symptom is repeatable.

Position depends on the platform. On most Hyundai applications the belt tensioner sits on the transmission & drivetrain assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Stock references leave Guangzhou within 7 working days. If 2742003000 needs a production run, allow 25-35 days depending on quantity and surface treatment. The schedule is confirmed in writing when the order is placed.

Aftermarket belt tensioner 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.

Three checks: the code printed on your old part must read 2742003000; 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.
