Review on MTC 3083 103 203 07 74 Thermostat Mercedes by Rudy Santos

Revainrating 5 out of 5

Great fit + great function = better than OEM

Media failed to load. The thermostat cover works great and is an exact OEM fit. The included air bleeder is a very useful and handy feature to remove excess air from the cooling system. When replacing the thermostat and cover, I used a new gasket from the dealer plus a few drops of red RTV sealant around the rim to ensure reliability. Then after everything had settled and dried I started the car and burped the system with the bleed screw until no more air bubbles came out, after which I sealed the whole thing with the supplied cap screw and copper crush washer. All in all a great and affordable thermostat cover that will outperform the original factory design and will work well with any applicable M104 engine.

Pros
  • Delivery was very quick
Cons
