Engine Mount Isolator – Mazda (ec0139970)

Engine Mount Isolator locates the engine, transmission or subframe and isolates vibration from the body. Rubber hardness and internal voiding are tuned to a specific powertrain, so a stiffer or softer substitute changes how much noise reaches the cabin.

Replace the Engine Mount Isolator when engine movement is visible when the throttle is blipped, when a clunk appears on take-up, or when the rubber has separated from the metal. Replacing one worn mount often shows up the next one.

For this Engine Mount Isolator the reference is ec0139970, in our Engine Mounts & Covers range. Compare it with the number on the part you are replacing rather than with a photograph.

This is MAZDA dealer-sourced stock rather than an equivalent, so the number on the Engine Mount Isolator traces straight back to the manufacturer.
