Review MITSUBISHI Radiator fits MIRAGE 1997–2002

The **Mitsubishi MR204591 Radiator (1997 2002 Mirage)** is a high-performance, precision-engineered cooling component designed exclusively for Mitsubishi s 4G63 and 4G93 inline-four engine applications found in the Mirage, Eclipse, and Lancer models from the late 1990s. Crafted from durable **aluminum alloy**, this radiator features a **cross-flow design** optimized for maximum airflow efficiency, ensuring optimal heat dissipation even under demanding driving conditions. The **91mm core depth** balances compactness with robust cooling capacity, making it ideal for tight engine bays while maintaining superior thermal regulation. Constructed with **high-quality brass or copper tubes** and reinforced with **polyester or nylon core support**, this radiator is built to withstand the rigors of daily driving, preventing overheating and engine stress. The **dual-row design** enhances heat exchange efficiency, while the **integrated pressure cap** (typically rated at 1.5 1.8 bar) helps maintain proper coolant pressure, reducing the risk of cavitation and ensuring consistent performance. Whether installed in a stock or modified setup, this radiator delivers reliable cooling for both urban commuting and spirited highway cruising, making it a trusted upgrade for enthusiasts and mechanics alike. Its compatibility with **Type 2 and Type 4 coolant** further expands its versatility, ensuring long-term durability and protection against corrosion.

### Pros and Cons of buying a Mitsubishi MR204591 Radiator (1997 2002 Mirage)

1. **Compatibility and Fitment** This radiator is designed specifically for the 1997 2002 Mitsubishi Mirage (and related models like the Eclipse and Lancer). It ensures a proper fit without modifications, reducing the risk of leaks or improper installation.

2. **Reliability** Mitsubishi s radiators from this era were generally built to last, especially if the vehicle was well-maintained. The MR204591 is a standard replacement part, meaning it has undergone testing for durability.

3. **Ease of Installation** Since it s an OEM (Original Equipment Manufacturer) or high-quality aftermarket part, it should install similarly to the original, making the job simpler for most mechanics or DIYers with basic tools.

4. **Performance** A properly functioning radiator ensures efficient cooling, preventing overheating and engine damage. This part is critical for long-term engine health, especially in stop-and-go traffic or hot climates.

5. **Warranty Coverage** If purchasing from a reputable dealer or aftermarket supplier, some parts may come with warranties, offering peace of mind against defects.

6. **Cost-Effective for Long-Term Use** While the upfront cost may seem higher than a cheap generic part, a quality radiator reduces the risk of frequent cooling system failures, saving money in the long run.

---

1. **Age and Potential Wear** Since this radiator is for older vehicles (1997 2002), it may have been sitting in inventory for years. Some units could be affected by moisture damage, rust, or degradation if not stored properly.

2. **Price Compared to Alternatives** The MR204591 may be more expensive than generic or "universal" radiators, which could be a deterrent for budget-conscious buyers. However, these cheaper options may not fit perfectly or last as long.

3. **Availability and Lead Times** Depending on the supplier, this specific part might not be in stock immediately, requiring ordering from a distributor, which could delay repairs.

4. **Potential for Counterfeit Parts** If buying from untrusted sources (e.g., eBay without seller verification or unknown marketplaces), there s a risk of receiving a counterfeit or low-quality replica that fails prematurely.

5. **Additional Repairs May Be Needed** If the radiator failure is due to a larger issue (e.g., a failing water pump, thermostat, or coolant leaks), simply replacing the radiator won t fully resolve the problem. A thorough inspection of the cooling system is recommended.

6. **Environmental Concerns** Older radiators may contain materials that are less eco-friendly than modern alternatives, though this is less of a practical concern for the buyer.

### **Conclusion**

The Mitsubishi MR204591 radiator is a solid choice for restoring or maintaining the cooling system of a 1997 2002 Mirage, Eclipse, or Lancer. Its primary advantages lie in its **proven fitment, reliability, and performance**, which are critical for preventing engine damage from overheating. However, buyers should be cautious about **potential age-related issues, counterfeit parts, and the need for a full cooling system check**.

If you prioritize **long-term reliability and proper function**, investing in this radiator is justified. If cost is the primary concern, a high-quality aftermarket alternative (e.g., from brands like ACDelco, Fram, or Denso) could be a viable substitute, provided it matches the OEM specifications.

---

### **Recommendation**

1. **Buy from a Trusted Source** Purchase from a reputable auto parts dealer (e.g., RockAuto, Amazon with verified sellers, or a local Mitsubishi specialist) to avoid counterfeit or damaged parts.

2. **Inspect the Radiator Before Purchase** If possible, examine the part for signs of rust, leaks, or damage. Request a return policy if buying online.

3. **Check the Entire Cooling System** Replace the radiator alongside other aging components like the **water pump, hoses, thermostat, and coolant** to prevent future failures.

4. **Use High-Quality Coolant** Always use the manufacturer-recommended coolant (e.g., Mitsubishi s long-life coolant or a compatible OAT blend) to extend the life of the radiator and cooling system.

5. **Consider a Remanufactured Option** If cost is a concern, a remanufactured radiator (from companies like RemanXpress or local core shops) can offer a balance between quality and affordability.

**Final Verdict:** The MR204591 is a **reliable and recommended choice** for owners who want a direct OEM replacement. For those on a tighter budget, a well-reviewed aftermarket alternative with the same specifications can be a practical alternative, but always ensure compatibility. Prioritize **proper installation and system maintenance** to maximize the radiator s lifespan.
