Review MERCEDES benz 4.7l Oem Right Engine Motor Cylinder Head fits GL450 4MATIC 2007–2012

The **Mercedes-Benz 2730100501 (07-12 GL450 X164, 4.7L 4MATIC Right Engine Motor Cylinder Head)** is a precision-engineered component designed specifically for the iconic M273 V8 engine found in the Mercedes-Benz GL-Class (W164) and other high-performance models from the 2007 to 2012 model years. This cylinder head is a critical part of the engine s combustion system, responsible for housing the intake and exhaust valves, spark plugs, and camshaft components, all of which work in unison to optimize power delivery, efficiency, and reliability. Crafted from high-grade cast iron or aluminum (depending on the variant), this cylinder head is engineered to withstand the extreme thermal and mechanical stresses of a 4.7-liter naturally aspirated V8, delivering robust performance while maintaining structural integrity over thousands of miles.

The design of this cylinder head incorporates advanced features tailored to the M273 engine s performance requirements. It features a dual overhead camshaft (DOHC) configuration, with each cylinder bank operating independently to ensure balanced airflow and combustion. The intake and exhaust ports are meticulously shaped to maximize volumetric efficiency, allowing for optimal fuel-air mixture entry and exhaust gas expulsion, which contributes to the engine s smooth operation and torque output. Additionally, the cylinder head is equipped with high-performance valve springs, retainers, and hydraulic lifters to minimize valve float and ensure precise valve timing, even under high-load conditions.

For vehicles equipped with the **4MATIC all-wheel-drive system**, this cylinder head is specifically designed for the right-side engine installation, ensuring proper alignment with the drivetrain components and maintaining optimal cooling and lubrication flow. The head is also compatible with the engine s advanced fuel injection system, including direct and port injection, allowing for precise fuel delivery and combustion optimization. The inclusion of integrated cooling passages and oil galleries ensures that critical components remain within optimal operating temperatures, reducing the risk of thermal stress and prolonging the engine s lifespan.

When replacing or maintaining this cylinder head, it is essential to use genuine Mercedes-Benz parts to ensure compatibility with the engine s control modules, sensors, and calibration settings. The cylinder head is often paired with components such as the intake manifold, exhaust manifold, and valve cover, all of which must be inspected and serviced in accordance with the manufacturer s specifications. Whether used in a restoration project, performance upgrade, or routine maintenance, this cylinder head represents the pinnacle of Mercedes-Benz engineering, delivering the reliability and power expected from one of the brand s most legendary V8 engines.

### **Pros and Cons of Buying a Mercedes-Benz GL450 (W164) with the 4.7L V8 4MATIC Right-Hand Drive (RHD) Engine (2007 2012)**

#### **Pros**

1. **Strong Engine and Performance**

- The **4.7L V8 4MATIC** (M273) is a robust, naturally aspirated engine known for its reliability and torque (360 400 hp, depending on model year). It delivers strong towing capacity (up to 5,500 lbs in some trims) and smooth power delivery, making it well-suited for SUV driving.

- The **4MATIC all-wheel-drive system** provides excellent traction in various conditions, which is beneficial for off-road or winter driving.

2. **Luxury and Comfort**

- The W164 GL450 is a full-size luxury SUV with high-quality materials, spacious seating (seven-passenger options), and a refined cabin. The **2007 2012 models** feature a comfortable ride, quiet interior, and premium amenities like leather upholstery, wood/aluminum trim, and advanced climate control.

- The **2010 facelift models** introduced minor improvements, such as a revised front grille and updated interior features.

3. **Reliability (Compared to Competitors)**

- While not as bulletproof as some German engines (e.g., the 3.0L V6 in the ML350), the **4.7L V8 is generally reliable** if maintained properly. Many examples with **under 100,000 miles** run well with basic upkeep.

- The **transmission (7G-Tronic automatic)** is smooth and durable, though some early models may require fluid changes to prevent wear.

4. **Resale Value and Prestige**

- Mercedes-Benz retains strong resale value, and the GL450 remains a desirable luxury SUV. Owning one carries prestige, especially in markets where German brands are highly regarded.

- The **RHD version** is rarer than LHD, which could make it more appealing to collectors or buyers in countries where RHD vehicles are preferred.

5. **Off-Road and Towing Capability**

- The **4MATIC system** and available **4WD modes** (e.g., "Snow," "Sand," "Rock") make it capable for light off-roading or towing heavy loads. Some trims come with **air suspension** for adjustable ride height.

- The **towing package** (when available) enhances its utility for trailers or boats.

6. **Available Tech (Later Models)**

- **2010 facelift models** introduced features like **Bluetooth, USB ports, and a more user-friendly infotainment system** (though still basic by modern standards).

- Some luxury trims included **adaptive cruise control, lane-keep assist, and advanced lighting**.

---

#### **Cons**

1. **High Maintenance Costs**

- **Engine oil changes** (every 10,000 15,000 miles, using MB-approved synthetic oil).

- **Timing belt replacement** (if applicable some 4.7L engines have chains, but related components may still need attention).

- **Transmission fluid changes** (critical for longevity, often overlooked).

- **Suspension and steering components** (struts, bushings, and control arms wear out over time).

- **Dealer labor rates** are typically higher than independent shops, adding to expenses.

2. **Fuel Efficiency is Poor**

- The **4.7L V8 averages 12 15 MPG combined**, making it one of the least efficient luxury SUVs. Fuel costs will be significantly higher than smaller or hybrid alternatives.

- **Diesel options (e.g., OM642 V8)** were available in some markets but are not common in RHD models.

3. **Common Reliability Issues**

- **Oil consumption**: Some 4.7L V8 engines develop **oil leaks or excessive consumption**, particularly around **valve cover gaskets or oil filter housing gaskets**. Regular oil checks are a must.

- **Transmission problems**: Early **7G-Tronic models** (pre-2010) can develop **rough shifting or slipping** if fluid isn t changed properly. Later models improved but are still not as robust as ZF transmissions in newer Mercedes.

- **Electrical gremlins**: The **infotainment system** (especially in older models) can be finicky, with issues like **screen freezes or radio malfunctions**.

- **Suspension wear**: The **air suspension (if equipped)** can fail, leading to **uneven ride height or leaks**. Coil springs are more reliable but still prone to wear.

- **Water pump and cooling system**: The **thermostat housing and water pump** can fail, leading to **overheating**. The **coolant expansion tank** is also a common failure point.

4. **Outdated Safety Features**

- **2007 2012 models lack modern safety tech** like **automatic emergency braking, blind-spot monitoring, or advanced driver-assistance systems**. Crash test ratings are **not as high as newer SUVs** (e.g., 2015 models with improved structure).

- **Rear visibility is poor** due to the large size and lack of **360-degree cameras** (a later addition).

5. **Depreciation and Market Demand**

- While Mercedes retains value, the **GL450 is not as sought-after as smaller luxury SUVs** (e.g., E-Class, CLS, or even the newer GLE). This means **resale value drops faster** than some competitors.

- **RHD models are even rarer**, which can limit the used market and make parts/sales more difficult in some regions.

6. **Size and Maneuverability**

- The **W164 is large and heavy**, making it **difficult to park in tight spaces** and **fuel-inefficient in city driving**.

- **Turning radius is wide**, which can be an issue in urban environments.

7. **Noise and Vibration**

- Some owners report **wind noise at highway speeds** and **engine vibrations** (especially in the cabin), though this varies by build year.

- **Road noise** can be intrusive compared to newer, better-insulated SUVs.

8. **Recall and Warranty Issues**

- Older models may have **unaddressed recalls** or **expired warranties**, leaving owners responsible for costly repairs.

- **Extended warranties** are often recommended but add to the upfront cost.

---

### **Conclusion**

The **Mercedes-Benz GL450 (W164) 4.7L V8 4MATIC RHD (2007 2012)** is a **capable, luxurious, and capable SUV** that excels in **towing, off-roading, and long-distance comfort**. However, it comes with **significant drawbacks**, particularly **high maintenance costs, poor fuel economy, and reliability concerns** that require diligent upkeep.
