Review JEEP Grandcher Air Injection Pump fits 2014

The **Jeep 341 AM8714 Grand Cherokee (2014) Air Injection Pump** is a critical component of the vehicle s emissions control system, specifically designed to enhance the performance and efficiency of the 5.7L HEMI V8 engine by reducing harmful exhaust emissions. This high-performance air injection pump operates by forcing ambient air into the exhaust manifold, where it mixes with hot exhaust gases to promote the oxidation of unburned hydrocarbons and carbon monoxide before they exit the tailpipe. Engineered with precision, the **AM8714** features a robust impeller-driven mechanism that ensures consistent airflow, even under high-stress conditions such as aggressive driving or towing. Constructed from durable materials, including corrosion-resistant metals and reinforced seals, this pump is built to withstand the demanding environments typical of off-road and heavy-duty applications. Its compact yet robust design allows for seamless integration into the Jeep s exhaust system, ensuring reliable operation without compromising the vehicle s performance. Whether used in a stock configuration or as part of a modified exhaust system, this air injection pump plays a vital role in maintaining compliance with emissions regulations while supporting the engine s overall efficiency. For Jeep enthusiasts seeking to preserve their vehicle s performance and longevity, this component is an essential upgrade or replacement part, offering both reliability and compliance with modern emissions standards.

The Jeep 341 AM8714 Grand Cherokee (2014) with an air injection pump is a vehicle that offers a mix of practicality, off-road capability, and durability, but it also comes with some drawbacks. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Reliability and Durability**

The 3.6L Pentastar V6 engine (common in 2014 Grand Cherokees) is known for its robustness and longevity, especially when maintained properly. The air injection pump, while not as critical as in older engines with EGR systems, is part of the emissions control system and helps reduce harmful exhaust emissions. The overall build quality of the Jeep platform is generally solid, with a reputation for lasting well over 200,000 miles with proper care.

2. **Off-Road Capability**

The 2014 Grand Cherokee (especially in the Trailhawk or Overland trims) is well-equipped for off-roading. Features like locking rear differentials, all-wheel drive, and a higher ground clearance make it a capable choice for adventurers. The air injection pump is not directly related to off-road performance, but the vehicle s overall ruggedness is a major advantage.

3. **Comfort and Practicality**

The Grand Cherokee offers a spacious interior with comfortable seating for five (or seven in the tri-body models). The ride is smooth on pavement, and the SUV s size provides ample cargo space, making it practical for daily driving and family use. The air conditioning and heating systems are generally reliable, contributing to passenger comfort.

4. **Resale Value**

Compared to many SUVs in its class, the Jeep Grand Cherokee retains its value reasonably well, especially if well-maintained. The 3.6L Pentastar engine is also in demand for parts and modifications, which can be beneficial if you plan to keep the vehicle long-term.

5. **Aftermarket Support**

The Jeep platform has a strong aftermarket community, with readily available parts, upgrades, and modifications. This includes performance upgrades, suspension enhancements, and even emissions-related modifications if needed. The air injection pump, while not a high-maintenance component, can be replaced or bypassed if necessary.

6. **Fuel Efficiency (Compared to Competitors)**

While not the most fuel-efficient SUV in its class, the 3.6L Pentastar engine offers decent mileage for a V6 (around 18-22 MPG combined, depending on trim and driving conditions). This is better than many larger SUVs with V8 engines.

7. **Technology and Features**

The 2014 model year includes modern features such as Uconnect (a touchscreen infotainment system), available Bluetooth, USB ports, and safety features like stability control and traction control. These add to the vehicle s appeal for tech-savvy buyers.

---

### **Cons**

1. **Air Injection Pump Reliability**

The air injection pump itself can be a point of concern. While modern engines like the Pentastar rely less on air injection systems compared to older engines, the pump can still fail over time. Symptoms of a failing pump include check engine lights, reduced engine performance, or unusual noises from the exhaust system. Replacement costs can range from $200 to $500, depending on labor and parts. Additionally, some owners report that the pump can be finicky and may require frequent replacement or bypassing.

2. **Maintenance Costs**

While the Pentastar engine is reliable, it does require regular maintenance to avoid costly repairs. This includes oil changes, timing belt replacement (every 100,000 miles), and potential issues with the transmission (especially in automatic models). The air injection pump adds another layer of maintenance, as it may need periodic checks or replacements.

3. **Transmission Issues**

Some 2014 Grand Cherokees equipped with the 6-speed automatic transmission (especially in certain trims) have reported transmission problems, including rough shifting or failure. This can be a significant drawback if the transmission is not serviced properly or if the vehicle has a history of neglect.

4. **Rust and Corrosion**

Jeep vehicles, especially older models, are prone to rust, particularly in areas like the wheel wells, rocker panels, and undercarriage. The 2014 Grand Cherokee is no exception, and rust can lead to structural issues if left unaddressed. A thorough inspection of the vehicle s undercarriage is essential before purchase.

5. **Resale of the Air Injection Pump**

If you decide to sell the vehicle later, the air injection pump may not be a selling point. Buyers often prioritize reliability and low maintenance, and a history of pump issues could deter potential buyers. Some may even choose to bypass the pump entirely, which can simplify ownership but may not be ideal for all buyers.

6. **Fuel Economy**

While the Pentastar engine is more fuel-efficient than many V8 engines, it still lags behind smaller four-cylinder engines in its class. If fuel efficiency is a top priority, you may find more economical options in other SUVs.

7. **Noise and Vibration**

Some owners report that the Grand Cherokee can be noisy, especially on highway speeds, due to wind noise and road noise. The interior materials are also not as premium as some competitors, which can affect the overall driving experience.

8. **Electrical Gremlins**

Like many vehicles from this era, the 2014 Grand Cherokee can suffer from electrical issues, such as faulty sensors, wiring problems, or Uconnect system glitches. These can be frustrating and costly to diagnose and repair.

---

### **Conclusion**

The 2014 Jeep Grand Cherokee with the 341 AM8714 air injection pump is a capable and versatile SUV that excels in off-road scenarios and daily driving. Its reliability, especially with the Pentastar engine, makes it a strong contender for buyers looking for a durable and practical vehicle. However, the air injection pump adds a layer of potential maintenance concerns, and other issues like rust, transmission problems, and electrical gremlins can be drawbacks if not properly addressed.

The decision to buy this vehicle ultimately depends on your priorities. If you value off-road capability, durability, and are prepared for some maintenance (including potential air injection pump issues), this Jeep could be a great choice. On the other hand, if you prioritize low maintenance, fuel efficiency, or a more premium interior, you may want to consider alternatives.

---

### **Recommendation**

1. **Thorough Inspection**: Have a trusted mechanic perform a pre-purchase inspection, focusing on the air injection pump, transmission, rust, and overall engine health. Check for any check engine light codes and address them before buying.

2. **Maintenance History**: Ensure the vehicle has a complete and documented maintenance history, including oil changes, timing belt replacements, and any past repairs related to the air injection pump or transmission.

3. **Budget for Repairs**: Be prepared for potential maintenance costs, especially for the air injection pump, transmission, and rust repairs. Set aside funds for these expenses to avoid financial strain later.

4. **Consider Bypassing the Pump**: If the air injection pump is a recurring issue, you may want to research bypassing it. This involves disabling the pump to eliminate check engine lights and potential performance issues, though it may not be ideal for all buyers (e.g., those selling the vehicle later).

5. **Alternative Options**: If the air injection pump concerns you too much, consider a Jeep Grand Cherokee with a different engine (such as the 3.0L EcoDiesel or a turbocharged 2.4L engine) or a different year with fewer known issues.

6. **Buy from a Reputable Seller**: Purchase from a dealership with a strong warranty or from a private seller with a clean history. Avoid vehicles with salvage titles or unclear maintenance records.

In summary, the 2014 Jeep Grand Cherokee is a solid SUV with many strengths, but the air injection pump and other potential issues require careful consideration. If you are willing to invest time and money in maintenance, it can be an excellent long-term vehicle. Otherwise, weigh the pros and cons against alternatives to ensure it aligns with your needs.
