### **Cons**

1. **Higher Upfront Cost**

The F48U86A01 is **more expensive** than the stock blower motor or some generic aftermarket alternatives. Pricing typically ranges between **$200 $300**, depending on the retailer and any additional accessories included.

2. **Potential for Overheating in Extreme Conditions**

While the blower motor improves airflow, **extreme ambient temperatures or heavy-duty towing** may still stress the cooling system. Some users report that in very hot climates, additional cooling measures (like an intercooler upgrade) may be necessary to fully optimize performance.

3. **Mixed Reviews on Longevity in Aggressive Use**

While most users report **long-term reliability**, a small percentage of owners particularly those who **push the engine hard** (e.g., heavy towing, frequent high-RPM use) have experienced **premature bearing wear** or motor failure. This is less common than with stock motors but still a consideration.

4. **Requires Proper Installation for Optimal Performance**

If not installed correctly (e.g., improper belt tension, misalignment), the blower motor may **overheat or fail prematurely**. Ensuring a **clean installation** and using the correct belt (often a 5PK2400 or similar) is crucial.

5. **Limited Availability of OEM Parts**

Since this is an aftermarket part, **OEM replacement components** (like seals or bearings) may be harder to source if the motor fails. However, Smith does provide some support for repairs.

6. **Not a Direct OEM Replacement in All Cases**

Some users with **modified or heavily upgraded cooling systems** (e.g., custom intercoolers, larger radiators) may find that the F48U86A01 doesn t fully match their system s demands, requiring further adjustments.

---
