01 · Housing and Seal
Direct Fit into the Cooling Circuit
The unit is produced around the listed Mercedes-Benz applications, with the housing, wax element and sealing arrangement matched to the original coolant outlet position.
Compare the housing shape, the connector position and the seal seat with the removed thermostat before fitting.
02 · Temperature Regulation
Stable Warm-Up and Cooling
The thermostat restricts coolant circulation while the engine warms up, then opens at its set point to allow flow through the radiator. This keeps combustion and cabin heating within their designed range.
A worn thermostat is a common cause of slow warm-up, fluctuating temperature readings or coolant loss from a pressure build-up.
03 · Replacement Practice
Coolant Refill and Bleeding
Replacement normally requires draining part of the cooling system, fitting the new thermostat and refilling with the specified coolant.
The cooling system must be bled correctly afterwards. Fitment is confirmed by OE number and VIN, as engine variants differ within the same model family.

Application
Application and Replacement Context
The thermostat is used in the cooling system of the listed Mercedes-Benz models. Over time the wax element and seal can degrade, so the valve opens late, opens early or fails to seal. Drivers may notice a temperature gauge that climbs slowly, an over-cooled engine in winter, or repeated coolant pressure warnings. Replacing the thermostat restores correct warm-up behaviour and stable operating temperature, which supports fuel efficiency and reduces stress on the engine and cabin heater.
Installation and Maintenance
- Confirm OE 2712000315 and the engine variant before starting work.
- Allow the engine to cool fully, then drain the cooling system to the required level.
- Remove the existing thermostat and clean the sealing surface.
- Fit the new thermostat and reconnect the coolant outlet as per the service procedure.
- Refill with the specified coolant mixture and bleed the system until the thermostat opens and the heater runs hot.
Quality and Ordering Notes
- Verify the OE number and the listed Mercedes-Benz application before ordering.
- Check the seal seat and the housing for damage before installation.

What are the symptoms of a failed thermostat?
Slow warm-up, an engine that runs cold in winter, a temperature gauge that fluctuates, or overheating when the valve sticks closed.
What are the cross-reference numbers?
The catalogue lists interchange references 2712000115 and 2712000215 alongside the primary OE 2712000315.
Does the cooling system need bleeding?
