Mazda2 Engine Mount Guide 2025: LH RH Rear Explained with Genuine OEM Parts
Engine mounts are among the most overlooked components on the Mazda2, yet they directly affect ride quality, cabin noise, and drivetrain integrity. This guide explains what LH, RH, and Rear mounts do, how to spot failure, and which genuine Mazda parts fit your specific model.
If you own a Mazda2 — whether the pre-facelift DE generation (2009–2014) or the sleeker Skyactiv-era DJ generation (2015 onwards) — engine mounts are one of those components you rarely think about until they remind you, loudly and uncomfortably, that they exist. These modest but critical parts hold your engine in place, absorb vibration, and protect both you and your car from the mechanical chaos happening under the hood every time you turn the key. Understanding what engine mounts do, how they fail, and which genuine parts fit your specific Mazda2 can save you money, prevent further damage, and restore the smooth, quiet ride this car was engineered to deliver.
What Engine Mounts Actually Do
An engine mount is a structural bracket, typically composed of a steel outer shell bonded to a rubber or hydraulic rubber core, that connects your engine to the vehicle's subframe or chassis. On the Mazda2, the engine is a transversely mounted four-cylinder unit, which means it sits sideways in the engine bay. This layout generates specific torque forces that push and pull the engine in predictable directions during acceleration, braking, and gear changes. Engine mounts resist those forces, keeping the engine aligned and stationary relative to the body of the car.
Beyond structural support, engine mounts serve as vibration isolators. The rubber compound inside each mount acts as a buffer, absorbing the oscillations produced by combustion cycles and rotating components before they can travel through the chassis and into the cabin. On the Mazda2, which is designed as a refined and comfortable daily commuter, this noise and vibration isolation is particularly important to the driving experience. A healthy set of mounts means you feel the engine when you want to — during spirited acceleration — and forget it is there the rest of the time.
LH, RH, and Rear: Understanding the Three Mount Positions
The Mazda2 uses three engine mounts in its standard configuration: the Left-Hand (LH) mount, the Right-Hand (RH) mount, and the Rear mount. Each one occupies a distinct position in the engine bay and performs a slightly different mechanical role depending on where it sits in relation to the engine's center of mass and the direction of torque application.
The RH mount sits on the passenger side and is typically the primary structural mount on front-wheel-drive vehicles like the Mazda2. On the 2009–2014 model, this is a hydraulic mount — meaning it contains fluid chambers in addition to rubber — which makes it particularly effective at damping low-frequency vibrations at idle. It is also the mount most exposed to heat from the exhaust system and engine bay temperatures, making it statistically the most common first point of failure. On the 2015-onwards 1.5 A/T model, this corresponds to genuine Mazda part number D09T-39-060. For the 1.3 A/T variant of the same generation, the correct RH mount is DB1M-39-060A.
The LH mount sits on the driver's side and is primarily responsible for resisting the torque reaction forces generated during acceleration. When you press the accelerator, the engine tries to rotate in the opposite direction to the crankshaft — the LH mount pushes back against this rotational tendency, keeping the engine from lifting or twisting excessively. On the 2009–2014 Mazda2 with a 1.5 A/T, the LH mount carries part number DL33-39-070, while certain 2009–2014 configurations use DL34-39-070. The 2015-onwards 1.3 A/T LH mount is identified as DA6V-39-070B.
