Frequently Asked Questions

Does this include the gasket/seal?
Yes. This assembly comes with the primary rubber seal pre-installed on the housing, ensuring a factory-tight fit against the engine block.
Why should I replace the whole housing instead of just the thermostat?
On the M274 engine series, the thermostat is integrated into the plastic housing. The housing itself is a common failure point due to "heat soaking" which makes the plastic brittle. Replacing the entire assembly is the only way to guarantee a long-term fix and prevent future coolant leaks.
Will this fix my "P0128" Check Engine Light code?
Likely. P0128 indicates that the engine is not reaching operating temperature fast enough, which is the classic symptom of a thermostat that is "stuck open."
Is this compatible with the 2.0L Turbo engine?
Yes. This part number (A2742003100) is the primary thermostat for the 2.0L 4-cylinder Turbo (M274) engine found across most C-Class, E-Class, and GLC models from 2015 onwards.
