Review CHRYSLER TRUCKS Town Rear Cylinder Head Assembly Oem 3.8l fits COUNTRY 2001–2010

The **Chrysler 4694686AB 2001 2010 3.8L V6 Rear Cylinder Head** is a meticulously engineered component designed to deliver reliable performance and durability in the iconic Town & Country minivan platform. Part of the legendary **3.8L Magnum V6 engine family**, this cylinder head is crafted from high-quality cast iron, ensuring robust strength and resistance to thermal stress under demanding driving conditions. The head features a **four-valve-per-cylinder design**, with precision-machined intake and exhaust ports optimized for efficient airflow, enhancing both power delivery and fuel economy. The **pushrod-actuated valve train** incorporates durable rocker arms and hardened valve springs, providing smooth operation and minimizing wear over extended mileage. This cylinder head is equipped with **separate intake and exhaust manifolds**, allowing for independent tuning and easier maintenance, while the **integrated spark plug wells** ensure proper ignition system alignment. Built to meet the stringent emissions standards of the early 2000s, it includes **PCV (Positive Crankcase Ventilation) passages** and **EVI (Evaporative Emissions) ports** to comply with federal regulations. Whether installed in a classic Town & Country for restoration or as a replacement in a daily-driven vehicle, this cylinder head exemplifies Chrysler s commitment to blending performance with practicality. Its compatibility with the **2001 2010 model years** makes it a sought-after part for enthusiasts seeking to restore or upgrade their minivan s powerplant, ensuring a seamless fit with the engine block and supporting components.

### Pros and Cons of Buying a 2001 2010 Chrysler Town & Country (3.8L V6) Rear Cylinder Head (Part # 4694686AB)

1. **Common and Widely Available** The 3.8L V6 engine in the Town & Country is one of the most common Chrysler engines from this era, meaning parts, labor, and aftermarket support are abundant. This makes repairs and maintenance more accessible and cost-effective.

2. **Proven Reliability (When Maintained)** The 3.8L engine, when properly maintained, is known for lasting well over 200,000 miles. Many owners report few major issues if routine services (oil changes, timing belt, spark plugs, etc.) are performed on schedule.

3. **Affordable Replacement Parts** Since this is an older model, aftermarket and OEM replacement parts (including the cylinder head) are relatively inexpensive compared to newer vehicles. You can often find used or rebuilt heads for a fraction of the cost of a new one.

4. **Simple Design** The 3.8L engine is mechanically straightforward compared to modern turbocharged or complex fuel-injected systems. This means repairs can often be done with basic tools and without specialized diagnostic equipment.

5. **Good for Classic/Weekend Driving** If you re looking for a comfortable, spacious minivan for casual use rather than high-performance driving, the Town & Country is a solid choice. The 3.8L provides adequate power for highway driving and towing light loads.

6. **Potential for Modifications** Enthusiasts have successfully modified the 3.8L with performance upgrades (e.g., headers, cold air intake, ECU tuning), though these are more common in muscle cars like the Dodge Charger or Chrysler 300 than in the Town & Country.

7. **Discontinued but Still Supported** While Chrysler no longer produces this model, the engine remains popular enough that mechanics and shops are familiar with its quirks. This reduces the risk of running into a "orphaned" vehicle with no support.

1. **Timing Belt and Water Pump Failure** One of the most critical issues with the 3.8L engine is the timing belt and water pump, which must be replaced every **60,000 100,000 miles** (or as specified in the service manual). Failing to do this can result in catastrophic engine damage (bent valves, rod knock). Many owners forget or neglect this, leading to expensive repairs.

2. **Head Gasket and Cooling System Problems** The 3.8L is prone to **head gasket failure**, especially if the engine overheats or the cooling system is neglected. Symptoms include white smoke from the exhaust, coolant in the oil, or overheating. Replacing a head gasket (or even just cleaning the mating surfaces) can be labor-intensive and costly.

3. **Oil Leaks** The valve cover gasket, oil pan gasket, and rear main seal are common leak points. These leaks can lead to oil contamination and reduced performance if not addressed promptly.

4. **Electrical and Sensor Issues** Like many vehicles from this era, the Town & Country can suffer from **electrical gremlins**, such as faulty sensors, wiring harness problems, or failing alternators. These issues can trigger check engine lights and require diagnostic work.

5. **Transmission Problems (If Equipped with A604 or 42RE)** Some Town & Countries (especially those with the **A604 4-speed automatic**) have had transmission failures, including slipping gears or complete failure. If the vehicle has high mileage, a transmission flush or rebuild may be necessary.

6. **Fuel System Concerns** The **fuel injectors** and **fuel pump** can wear out over time, leading to rough idling, stalling, or poor acceleration. Replacing these components can be expensive, especially if the fuel pump fails and leaves you stranded.

7. **Interior Wear and Rust** Many Town & Countries from this era have **rust issues**, particularly in the floor pans, rocker panels, and wheel wells. If the vehicle has been exposed to salt or poor maintenance, rust repairs could add significant cost.

8. **Emissions and Modern Compliance** If you plan to keep the vehicle long-term, you may eventually face challenges with **emissions testing** or **smog certification**, especially in states with strict regulations. Some states have begun phasing out older vehicles from registration.

9. **Resale Value is Minimal** The Town & Country is not a highly sought-after vehicle, so resale value is low. If you plan to sell it later, you may not recoup much of your investment.

10. **Modern Safety and Tech Limitations** Compared to today s vehicles, the Town & Country lacks modern safety features (e.g., stability control, advanced airbag systems, backup cameras). It also has outdated tech (e.g., no Bluetooth, minimal infotainment).

Buying a **2001 2010 Chrysler Town & Country with a 3.8L V6 and a rear cylinder head (part # 4694686AB)** can be a **great budget-friendly choice** if you prioritize **space, comfort, and reliability for casual use**. The engine is durable when maintained, parts are cheap, and the vehicle is well-suited for family hauling or weekend driving.

However, **potential buyers must be prepared for common issues** like **timing belt neglect, head gasket failure, oil leaks, and electrical problems**. If you re not comfortable performing basic maintenance (or don t have access to a trusted mechanic), the upfront and long-term costs could add up quickly.

The **rear cylinder head (4694686AB)** itself is a **critical component**, and if it s failing, it s best to replace it with a **new or high-quality rebuilt unit** rather than risk further damage. A **pre-purchase inspection (PPI)** is **highly recommended** to check for:

- Timing belt/water pump condition

- Head gasket integrity (look for coolant/oil mixing)

- Transmission fluid condition

- Rust and structural integrity

- Electrical system functionality

---

- You re looking for a **reliable, spacious minivan** for low-mileage use.

- You **find a well-documented example** with a **clean service history**, especially for timing belt/water pump replacements.

- You **can t afford unexpected repairs** (e.g., head gasket failure, transmission issues).

- You **don t have access to a mechanic** for routine maintenance.

- You **prioritize modern safety and tech features** over classic minivan charm.

- **Replace the timing belt and water pump** if due (even if the seller says it s fine).

- **Check for oil leaks, coolant contamination, and transmission smoothness**.

- **Budget for potential head gasket or fuel system repairs** in the first few years.

If you re set on this vehicle and find one in **good condition with a serviceable engine**, it can be a **fantastic deal** especially if you re looking for a **no-frills, functional minivan**. However, if you re open to alternatives, consider a **used Honda Odyssey, Toyota Sienna, or Ford Windstar** for potentially better long-term reliability.
