OE 1202000122 — Fan Clutch for Mercedes-Benz

A supersession happens when the maker revises a fan clutch 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 1202000122 we list the current reference; ask our desk for written confirmation before a large order.

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 fan clutch the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Yes. Sample lots of 1202000122 are used by QC teams to benchmark dimension, material and finish before a volume commitment. Send the reference and we will quote the sample alongside the production price.

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.

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.
