### **Pros and Cons of buying a Dorman 698-070 Harmonic Balancer (190 Series)**

#### **Pros:**

1. **Compatibility** The Dorman 698-070 is specifically designed for the **190-series GM engines**, including the **L31, L34, L36, and L37** (common in vehicles like the 1990-1995 Chevrolet C/K Trucks, GMC Sierra, and some GMC Suburbans). This ensures a proper fit without modification.

2. **Quality Construction** Dorman is a well-known aftermarket brand that produces durable, high-quality replacement parts. The harmonic balancer is built to withstand the stresses of engine operation, reducing vibration and preventing damage to the crankshaft.

3. **Cost-Effective Solution** Compared to OEM (original equipment manufacturer) harmonic balancers, the Dorman part is often significantly cheaper while maintaining reliability. This makes it a practical choice for budget-conscious buyers.

4. **Ease of Installation** The part is designed to be a direct replacement, meaning it should install similarly to the original component. Most mechanics can replace it in under an hour with basic tools.

5. **Warranty Coverage** Dorman typically offers a **limited warranty** (usually 12-24 months), providing some peace of mind against premature failure due to defects in materials or workmanship.

6. **Prevents Further Damage** A failing harmonic balancer can cause excessive vibration, leading to cracked crankshaft pulleys, bent rods, or even engine damage. Replacing it proactively can save costly repairs down the line.

7. **Availability** Dorman parts are widely stocked at auto parts stores (AutoZone, O Reilly, RockAuto, etc.), making it easy to purchase without long waits.

#### **Cons:**

1. **Potential for Counterfeit Parts** Since Dorman is a popular brand, there is a risk of purchasing **counterfeit or low-quality knockoffs**, especially from untrusted online sellers. Always buy from reputable dealers or verified retailers.

2. **Mixed Reviews on Longevity** While generally reliable, some users report that the Dorman 698-070 may not last as long as an OEM part, particularly in high-mileage or heavy-duty applications. If the original balancer lasted 200,000 miles, the replacement might not match that durability.

3. **Noisy Operation (In Some Cases)** A few owners mention that the Dorman balancer can be slightly noisier than the original, though this is usually minor and not a dealbreaker unless the engine was previously very smooth.

4. **Requires Professional Installation** While the part is a direct fit, improper installation (e.g., not balancing the crankshaft properly) can lead to vibration issues. If the buyer lacks mechanical experience, professional installation is recommended.

5. **Limited Customization** Unlike some high-end aftermarket parts, the Dorman balancer does not offer performance upgrades (e.g., lighter weight for better power delivery). It is strictly a functional replacement.

6. **Potential for Rust or Corrosion** If the vehicle has been stored in harsh conditions (high humidity, salt exposure), the new balancer could still be susceptible to rust over time, though this is more of a general maintenance concern than a flaw with the part itself.

7. **Price Fluctuations** While generally affordable, prices can vary based on demand, retailer markup, or shipping costs, especially when ordering online.

### **Conclusion**

The **Dorman 698-070 harmonic balancer** is a **solid, cost-effective choice** for replacing a worn or damaged harmonic balancer in a **190-series GM engine**. It offers **reliable performance, ease of installation, and good availability**, making it a practical option for most drivers. However, it is not without drawbacks **potential counterfeit risks, mixed longevity reports, and the need for proper installation** are factors to consider.

If the vehicle is **high-mileage or used in demanding conditions**, some users might opt for a **higher-end aftermarket brand** (such as **Fel-Pro, Crane, or an OEM equivalent**) for potentially longer-lasting results. However, for most everyday drivers, the Dorman part provides **a good balance of quality and affordability**.

---

### **Recommendation**

- **Buy from a reputable source** (e.g., **RockAuto, AutoZone, or a trusted local auto parts store**) to avoid counterfeit parts.

- **Inspect the part upon arrival** ensure it matches the OEM specifications (e.g., correct rubber dampening, no visible defects).

- **Have a mechanic install it** if you are unsure about proper balancing and alignment.

- **Monitor for vibration or noise** after installation. If issues persist, consider a different brand or OEM replacement.

- **Consider a higher-end balancer** (e.g., **Fel-Pro 25000 or Crane C100**) if the vehicle has **high mileage or is used for towing/hauling**, as these may offer better durability.

**Final Verdict:** The **Dorman 698-070 is a good, budget-friendly choice** for most applications, but weigh the pros and cons based on your specific needs and engine condition. If reliability is a top priority, a slightly more expensive alternative may be worth the investment.
