Review MAZDA Genuine Engine Mount fits CX-7 2010–2012

The **Mazda EH48-39-070 Engine Mount** is a high-performance, precision-engineered suspension component designed specifically for Mazda vehicles equipped with the 2.5L or 3.5L Skyactiv-G or MZR inline-four engines, including models such as the Mazda3, Mazda6, CX-5, and Mazda CX-9. This mount is a critical part of the vehicle s suspension system, serving as the primary interface between the engine assembly and the chassis, ensuring optimal engine positioning, vibration dampening, and structural integrity. Crafted from durable, high-grade rubber reinforced with a robust steel core, the EH48-39-070 mount is engineered to withstand the rigors of daily driving, high-performance applications, and extended use under varying road conditions. Its unique design incorporates a **multi-layered rubber compound** that absorbs engine vibrations, reduces noise transmission, and minimizes harshness during acceleration, braking, and cruising, thereby enhancing both driver comfort and long-term engine protection. The mount s precise fitment ensures proper alignment of the engine and transmission, preventing excessive movement that could lead to premature wear on related components such as the exhaust manifold, intake system, or drivetrain. Whether installed in stock applications or as part of a tuning or modification package, this mount delivers reliable performance, contributing to a smoother ride and improved handling dynamics. Its compatibility with Mazda s advanced engine mounts makes it an ideal choice for both original equipment replacement and aftermarket upgrades, ensuring seamless integration with the vehicle s suspension geometry.

**Pros and Cons of buying a Mazda EH48-39-070 Engine Mount**

The Mazda EH48-39-070 is an engine mount designed for certain Mazda models, particularly those with the 2.5L or 3.0L Skyactiv-G engines (e.g., Mazda3, Mazda6, CX-5, CX-9). Below is a detailed analysis of its advantages and disadvantages.

### **Pros**

1. **Direct Fitment and Compatibility**

The EH48-39-070 is a genuine or high-quality aftermarket replacement designed specifically for Mazda vehicles. It ensures proper alignment and functionality, reducing the risk of installation errors that could lead to engine vibration or drivetrain issues.

2. **Durability and Quality**

Mazda engine mounts are built to withstand the stresses of daily driving, including road vibrations, acceleration, and braking forces. A high-quality aftermarket mount (such as those from brands like AEM, Spal, or Mann Filter) often matches or exceeds OEM standards in terms of materials and construction.

3. **Prevents Excessive Engine Movement**

Worn or broken engine mounts can cause excessive engine movement, leading to rattling noises, drivetrain misalignment, or even damage to the engine or transmission mounts. Replacing a faulty mount restores stability, improving ride quality and reducing wear on related components.

4. **Cost-Effective Maintenance**

Engine mounts are relatively inexpensive compared to the potential cost of repairing damage caused by a failing mount (e.g., transmission damage, exhaust leaks, or suspension wear). Replacing a mount early can prevent more expensive repairs down the line.

5. **Easier Installation**

Unlike some engine components, mounts are straightforward to replace. Most require only basic tools and can be done at home with minimal mechanical experience, saving labor costs if tackling the job yourself.

6. **Improved Driving Comfort**

A properly functioning engine mount reduces vibrations and noise, leading to a smoother, quieter ride. This is particularly noticeable in vehicles where the engine is mounted higher or less rigidly.

7. **Extended Engine and Transmission Life**

By maintaining proper engine positioning, a good mount helps prevent undue stress on the engine block, transmission, or exhaust system. This can contribute to longer-lasting components and fewer long-term issues.

### **Cons**

1. **Potential for Counterfeit or Low-Quality Parts**

The aftermarket for engine mounts is vast, and some sellers may offer cheap, knockoff, or poorly manufactured parts. These can fail prematurely, leading to recurring issues. Always purchase from reputable brands or authorized dealers to avoid this risk.

2. **Installation Challenges**

While engine mounts are relatively simple to replace, some vehicles may require additional steps, such as removing the exhaust or subframe. Improper installation such as overtightening or misalignment can cause new issues like binding or premature wear.

3. **Time-Consuming for DIYers**

Depending on the vehicle s design, replacing an engine mount may take several hours, especially if other components (e.g., the exhaust or subframe) need to be removed or adjusted. This can be inconvenient for those with limited time or mechanical skills.

4. **Hidden Damage from a Failed Mount**

If an engine mount has been failing for an extended period, the engine or transmission may have already sustained damage from excessive movement. In such cases, additional repairs (e.g., transmission alignment, exhaust repairs) may be necessary, increasing the overall cost.

5. **Limited Lifespan Compared to Other Components**

Engine mounts are subject to wear from constant vibration and stress. While they can last for hundreds of thousands of miles, they are not as durable as the engine itself. Eventually, they will need replacement, requiring ongoing maintenance.

6. **Potential for Over-Tightening**

Engine mounts must be tightened to the manufacturer s specifications. Over-tightening can damage the mount or the vehicle s frame, while under-tightening can lead to slop and rattling. This requires careful attention during installation.

7. **Environmental and Material Degradation**

Over time, rubber mounts can degrade due to heat, oil exposure, or UV radiation (if installed near the engine bay). This degradation can lead to cracking or hardening, reducing their effectiveness. Some aftermarket mounts use synthetic materials that may not perform as well in extreme conditions.

### **Conclusion**

The Mazda EH48-39-070 engine mount is a critical component that, when replaced with a high-quality part, provides significant benefits in terms of vehicle stability, comfort, and longevity. The pros such as improved ride quality, prevention of drivetrain damage, and cost-effectiveness far outweigh the cons for most drivers. However, the cons highlight the importance of selecting a reputable part, ensuring proper installation, and addressing any underlying issues before replacement.

For Mazda owners experiencing engine rattles, excessive movement, or unusual noises, replacing a worn mount is a prudent and often necessary maintenance step. The key is to choose a reliable brand, follow installation guidelines carefully, and address any secondary issues that may have arisen from the original mount s failure.

### **Recommendation**

If you are experiencing symptoms of a failing engine mount (e.g., rattling noises, engine movement, or transmission misalignment), **replace the EH48-39-070 mount as soon as possible**. Opt for an **OEM replacement part** (if available) or a **high-quality aftermarket brand** such as AEM, Spal, or Mann Filter, which are known for durability and compatibility. If you are not comfortable with the installation, have a trusted mechanic perform the job to ensure proper alignment and tightening.

Regularly inspect your engine mounts during routine maintenance, especially if your vehicle has high mileage or has been driven in rough conditions. Addressing mount issues early will save you from more costly repairs in the future.
