Review CHRYSLER Lhs New 3.5 Passenger Rebuilt fits CONCORDE YORKER INTREPID 1994–1997

The **Chrysler 4663490A 3.5L V6 Engine (LH Series, 1994 1997)** is a robust and reliable powerplant designed to propel the iconic **Concord, Yorker, and Intrepid** models through their respective eras with a blend of smooth performance and durability. Engineered as part of Chrysler s **LH platform**, this **3.5-liter (3500 cc) V6** features a **cast-iron block and aluminum cylinder heads**, a design choice that balances strength with weight efficiency. The engine s **multi-port fuel injection (MFI) system** ensures precise fuel delivery, optimizing throttle response and fuel economy while maintaining a refined driving experience. With a **compression ratio of 9.0:1**, this engine strikes a balance between power and efficiency, producing approximately **170 180 horsepower** (depending on year and tuning) and **200 210 lb-ft of torque**, making it well-suited for both city commuting and highway cruising. The **electronic throttle control (ETC)** and **distributorless ignition system** enhance reliability and reduce maintenance needs, while the **timed chain drive** (as opposed to a belt) eliminates the risk of catastrophic failure from a snapped serpentine belt a common concern in other V6 engines of the era.

This engine was specifically tuned for the **LH platform s front-wheel-drive (FWD) architecture**, where its compact yet powerful design allowed for seamless integration with the **4-speed automatic transmission (41TE or 42LE)** or the **5-speed manual (545RFE)**, depending on the model year and trim. The **intake manifold** features a **throttle body with variable air control (VAC)**, which helps refine idle quality and reduce emissions, while the **exhaust manifolds** are designed for efficient heat dissipation, contributing to the engine s longevity. One of the standout features of this powerplant is its **durability**, as it was built to withstand the demands of daily driving, long commutes, and occasional spirited acceleration qualities that made it a favorite among enthusiasts for its ability to handle modifications with relative ease. Whether paired with the **Concord s plush luxury**, the **Yorker s executive refinement**, or the **Intrepid s sportier handling**, this 3.5L V6 delivers a harmonious blend of comfort and capability, embodying the best of Chrysler s engineering in the mid-1990s.

For restoration or performance applications, this engine is a sought-after choice due to its **proven reliability** and **modular design**, which allows for upgrades such as **high-flow intake manifolds, performance camshafts, or even forced induction** (with proper supporting modifications). Its **cast-iron block** also makes it more resistant to warping compared to some aluminum-block engines, while the **aluminum heads** help keep weight down without sacrificing structural integrity. Whether you're seeking a **daily driver**, a **project car**, or a **performance build**, the **4663490A 3.5L V6** remains a dependable and character-rich engine that embodies the spirit of Chrysler s LH-era vehicles where practicality meets performance in a package that s as refined as it is resilient.

### **Pros and Cons of Buying a 1994 1997 Chrysler 4663490A (LHS Concourse, Yorker, Intrepid) with a 3.5L Engine**

#### **Pros**

1. **Reliable Base Engine** The 3.5L V6 (4663490A) is a proven Chrysler engine known for durability, especially when maintained properly. It is less prone to catastrophic failure compared to some other V6s of the era.

2. **Good Power for the Era** The 3.5L produces around **170 180 horsepower**, which was adequate for the time and provides decent acceleration for a mid-sized sedan. It handles highway driving and light towing well.

3. **Proven Transmission Options** These models commonly came with either a **4-speed automatic (41TE)** or a **5-speed manual**, both of which are reliable if properly serviced. The 41TE is a robust transmission when kept in good condition.

4. **Spacious Interior** The LHS Concourse, Yorker, and Intrepid share a roomy cabin with comfortable seating, ample legroom, and a well-appointed interior for the time. The rear seats are also reasonably spacious.

5. **Decent Fuel Economy** For a V6 sedan of this era, the 3.5L offers **18 22 MPG highway** (varies by model year and trim), which is better than many V8-powered competitors.

6. **Available Luxury Features** Higher trims (Concourse, Yorker) included features like **power windows, locks, cruise control, leather seats, and premium audio**, making them more comfortable than base models.

7. **Parts Availability** As a Chrysler product from the mid-'90s, parts are still widely available, though some may require searching for aftermarket or used options.

8. **Potential for Modifications** The 3.5L can be upgraded with **performance chips, intake/exhaust mods, or even a turbocharger** (though turbo kits are less common). The suspension can also be lowered or stiffened for better handling.

9. **Lower Cost of Ownership (Compared to Some Competitors)** While not the cheapest car to maintain, it is generally more affordable than luxury brands like BMW or Mercedes of the same era.

10. **Classic Chrysler Styling** The **1994 1997 Chrysler sedans** have a distinctive, aggressive front fascia and a bold stance that appeals to enthusiasts who enjoy classic American muscle-car aesthetics.

#### **Cons**

1. **Electrical and Computer Issues** Chrysler vehicles from this era are notorious for **electrical gremlins**, including **faulty sensors, wiring problems, and computer glitches** (e.g., check engine lights, transmission shifts, or ABS issues). This can lead to frequent diagnostic trouble.

2. **Transmission Problems (Especially 41TE)** While the **41TE automatic** is durable, it is prone to **slippage, rough shifting, or complete failure** if not maintained properly. Some owners report **solenoid or valve body issues**, which can be costly to repair.

3. **Rust Concerns** Many Chrysler sedans from this era, especially those driven in **snowy or humid climates**, suffer from **frame and subframe rust**. A thorough inspection of the **wheel wells, rocker panels, and undercarriage** is essential.

4. **Suspension Wear** The **control arms, bushings, and shocks** wear out relatively quickly, leading to **excessive noise, poor handling, and uneven tire wear**. Replacing these components is often a **necessary maintenance expense**.

5. **Head Gasket and Cooling System Issues** While the **3.5L V6 is generally reliable**, some units have had **head gasket failures** (especially if overheating occurs). The **thermostat housing and water pump** are also common failure points.

6. **Power Steering and Brake Problems** **Power steering pumps** and **brake master cylinders** can fail, requiring **expensive replacements**. Some models also suffer from **soft or spongy brakes** due to worn rotors or calipers.

7. **Interior Durability** The **plastic trim and upholstery** can degrade over time, especially in high-mileage examples. Some owners report **cracked dash panels** or **loose interior components**.

8. **Resale Value** Chrysler sedans from this era do not hold their value well. Even well-maintained examples depreciate quickly, making them a **less attractive long-term investment**.

9. **Potential for Hidden Repairs** Many of these cars have **unreported accidents or poor maintenance histories**, leading to **hidden structural damage or neglected mechanical issues**. A **pre-purchase inspection is highly recommended**.

10. **Market Competition** There are **plenty of alternatives** (e.g., **Ford Taurus, Chevrolet Lumina, Oldsmobile Cutlass Supreme, or even Japanese sedans**) that may offer better reliability or lower ownership costs.

The **1994 1997 Chrysler LHS Concourse, Yorker, or Intrepid with a 3.5L V6** can be a **fun, comfortable, and capable daily driver** especially if you find one that has been **well-maintained**. The **3.5L engine is reliable**, the **interior is spacious**, and the **styling is distinctive**. However, **electrical issues, transmission concerns, rust, and suspension wear** are **common problems** that can turn this car into a **money pit** if not properly addressed.

### **Recommendation**

1. **Get a Pre-Purchase Inspection (PPI)** A **mechanic or Chrysler specialist** should thoroughly inspect the **engine, transmission, suspension, electrical system, and rust areas** before buying.

2. **Check Maintenance Records** Look for **regular oil changes, transmission fluid flushes, and cooling system servicing**. A car with **no service history** is a **big red flag**.

3. **Test Drive for Common Issues**

- Listen for **unusual noises** (knocking, whining, grinding).

- Check for **smooth shifting** (no hesitation or jerking in the transmission).

- Test **power steering, brakes, and electrical components** (windows, locks, lights).

- Look for **excessive play in the steering or suspension**.

4. **Inspect for Rust** **Lift the car and check the frame, subframe, and wheel wells** for **corrosion**. Even minor rust can lead to **structural weakness**.

5. **Verify Transmission Health** If possible, **check transmission fluid color and smell** (burnt odor trouble). A **41TE transmission** should shift smoothly without **slipping or jerking**.

6. **Consider a Lower-Mileage Example** Aim for **under 100,000 miles** if possible, but **focus on condition over mileage** a **150,000-mile car in great shape** may be a better buy than a **low-mileage lemon**.

- **Suspension refresh** ($500 $1,200)

- **Transmission service or rebuild** ($1,000 $3,000 )

- **Electrical diagnostics** ($100 $300 per issue)

- **Rust repairs** (varies widely)

8. **Buy from a Reputable Seller** **Dealerships, trusted private sellers, or auction houses with return policies** are safer than **shady online listings**.

9. **Consider a Used Parts Car First** If you re unsure, **buy a used parts car** to **learn the quirks** before committing to a daily driver.
