Review DODGE 5.7 Coolant Tank Reservoir fits RAM 1500 2013–2017

The **Dodge LT-DG2031 Coolant Tank Reservoir** is a precision-engineered, high-performance component designed exclusively for the **2013 2017 Ram 1500** equipped with the **5.7L HEMI V8 engine** (LT4 or LT9 variants). This **polypropylene coolant expansion tank** serves as a critical component of the engine s cooling system, ensuring proper fluid circulation, temperature regulation, and long-term protection against overheating. Crafted from durable, heat-resistant polypropylene, this reservoir is engineered to withstand the demanding thermal cycles of high-performance driving, providing reliable performance in both urban commutes and rugged off-road adventures. Its **clear, ribbed design** allows for easy visual monitoring of coolant levels, enabling drivers to quickly identify and address low-fluid conditions before they escalate into costly engine damage. The reservoir features a **secure, leak-proof cap** with a pressure relief valve to prevent overpressure and vacuum-induced leaks, while its **reinforced mounting bracket** ensures a snug, vibration-dampened fit beneath the hood, minimizing the risk of fluid spillage or system failure. Whether installed in a stock Ram 1500 or a heavily modified performance vehicle, this **OEM-replacement part** maintains factory specifications, including proper capacity, hose connections, and compatibility with the engine s cooling system components. Built to meet or exceed Chrysler s original equipment standards, it offers a seamless upgrade for vehicles experiencing coolant loss, system leaks, or wear from extended use, ensuring optimal engine longevity and efficiency.

### Pros and Cons of Buying a Replacement Coolant Tank Reservoir for a 2013 2017 Dodge Ram 1500 5.7L (LT-DG2031)

1. **Prevents Overheating and Engine Damage** A failing coolant reservoir can lead to air pockets in the cooling system, reducing efficiency and causing the engine to overheat. Replacing it ensures proper coolant circulation and prevents costly engine damage.

2. **Easy to Install** The coolant reservoir is a straightforward component to replace, typically requiring only basic tools (socket wrench, new hoses, and coolant). Many DIYers can complete the job in under an hour without professional help.

3. **Affordable Replacement Part** Aftermarket and OEM reservoirs are relatively inexpensive, usually costing between $20 and $60, depending on brand and quality. This makes it a cost-effective fix compared to major engine repairs.

4. **Extends Engine Lifespan** Maintaining a properly functioning cooling system helps keep the engine running smoothly, reducing wear and tear over time.

5. **Prevents Coolant Leaks** A cracked or damaged reservoir can cause coolant leaks, leading to low coolant levels and potential overheating. Replacing it eliminates this risk.

6. **Compatibility with Aftermarket Upgrades** If you plan to modify your truck (e.g., forced induction, high-performance cooling), a new reservoir ensures compatibility with upgraded systems.

---

1. **Potential for Counterfeit or Low-Quality Parts** Some aftermarket reservoirs may be poorly made, leading to early failure or leaks. Buying from reputable brands (e.g., ACDelco, Fram, or genuine OEM) mitigates this risk but requires extra research.

2. **Coolant Flush May Be Required** If the old reservoir was leaking, it may have introduced contaminants into the cooling system. A full flush (or at least a partial drain and refill) may be necessary to ensure clean coolant.

3. **Time and Effort for Installation** While simple, the process involves draining coolant, removing old hoses, and ensuring proper sealing. If not done carefully, air pockets can form, reducing cooling efficiency.

4. **Risk of Overlooking Underlying Issues** If the reservoir failure is due to a larger problem (e.g., a failing water pump, radiator leak, or head gasket issue), replacing just the reservoir won t fix the root cause. A thorough inspection is recommended.

5. **Coolant Spills and Waste** Draining coolant requires proper disposal (many auto parts stores accept it for recycling). Improper disposal can be environmentally harmful.

6. **Possible Compatibility Issues with Modified Systems** If the truck has been modified with non-standard cooling components (e.g., custom radiators or extended hoses), the new reservoir may not fit perfectly without adjustments.

---

Replacing a faulty coolant reservoir on a 2013 2017 Dodge Ram 1500 5.7L is a **highly recommended and cost-effective preventive measure**. The benefits preventing overheating, avoiding engine damage, and extending the truck s lifespan far outweigh the minor drawbacks, which are largely avoidable with proper research and installation techniques. The process is straightforward for most DIYers, and the part itself is inexpensive compared to the potential cost of engine repairs.

**If the reservoir is visibly cracked, leaking, or failing, replacing it should be a priority.** However, if you suspect deeper cooling system issues (e.g., persistent overheating, white smoke, or coolant loss), have a mechanic inspect the water pump, hoses, radiator, and head gaskets to address the root cause.

---

1. **Purchase a high-quality replacement** Opt for an OEM or reputable aftermarket brand (e.g., ACDelco, Fram, or Mopar) to avoid premature failure.

2. **Flush the cooling system** If the old reservoir was leaking, drain and refill the coolant to ensure no debris or contaminants remain.

3. **Check for leaks** Inspect hoses, clamps, and the radiator for signs of wear before installation.

4. **Use the correct coolant** Follow the manufacturer s recommendation (typically a 50/50 mix of ethylene glycol and water for the 5.7L Hemi).

5. **Consider professional help if unsure** If you re uncomfortable with the installation or suspect other cooling system issues, a mechanic can perform the repair safely.

6. **Monitor for future issues** Keep an eye on coolant levels and temperature gauges to ensure the replacement is functioning correctly.

**Final Verdict:** **Buy and replace the reservoir promptly if it s failing.** It s a small investment that can save you from much larger (and expensive) problems down the road.
