MB Parts Center identifies 177-200-79-01-64 as a Mercedes-Benz thermostat and lists 1772007901 as a replacement or reference number. The catalog page also shows 1772000815 as another replaced number and describes the part as new. This listing is for a thermostat, not a complete cooling-system kit. The available page does not provide verified dimensions, temperature rating, included gasket, or application details, so those attributes are omitted. Use both the compact MPN 1772007901 and the formatted catalog number 177-200-79-01-64 when checking catalogs. Confirm vehicle compatibility before ordering.
