| Maximum Rotational Speed | 2500 RPM |
| Material | Steel & Plastic |
This A-Premium fan blade replaces the front-side cooling fan on 6.7L Cummins-equipped Ram 2500/3500/4500/5500 trucks and is intended to restore or improve radiator airflow. It installs in the radiator fan assembly and is used whenever engine cooling demand is high, such as towing or heavy-duty duty cycles. The design combines steel and plastic construction with nine blades and a balancing ring to move substantial air while limiting vibration. A four-pin power connector and a 2500 RPM maximum rotational speed suggest it pairs with the truck's factory fan motor and control system. In practice you can expect effective heat dissipation under load and a comparatively quiet operation around the listed noise level. The package comes as a single unit and A-Premium backs it with a one-year unlimited-mileage guarantee. Buyers should note this is a direct replacement component rather than a performance upgrade, so fitment and installation verification for the specific model year is essential.
Best for: Reliability-focused buyers who prioritize restoring factory cooling performance on a Ram 3500 used for towing or heavy workloads and want a straightforward, factory-style replacement.
Less Ideal for: If you are seeking an aftermarket performance fan to significantly increase cooling capacity or a custom-fit upgrade for nonstandard setups, this replacement may not meet those goals.
- Designed for 6.7L Ram diesel engines and lists specific compatible model years for straightforward fitment
- Nine-blade design and balancing ring to move substantial airflow while minimizing vibration
- Mixed steel and plastic construction balances strength and weight for durability
- Four-pin connector and factory-style mounting make it compatible with factory fan motor systems

Choosing the Right Ram 3500 Cooling Fan: Key Factors to Consider
Airflow Capacity
Airflow capacity determines how much heat the fan can move away from the radiator and engine. Higher airflow values usually translate to better cooling under load, especially when towing or running at low speeds where natural airflow is limited.
Consider CFM equivalents or manufacturer-stated flow rates and weigh them against the typical operating conditions you put the truck through. Overly high airflow is not always necessary for light-duty use and can mean more noise or greater electrical draw, so choose a level that matches your cooling needs.
Motor Durability and Type
The motor is the most stressed component in a cooling fan, and its construction affects longevity and performance. Look for motors with sealed housings, thermal protection, and robust bearings that tolerate frequent starts and heavy-duty operating cycles.
Motor type also affects maintenance and heat tolerance. Brushless or high-quality brush motors often run cooler and last longer under continuous duty, which matters if you frequently tow heavy loads or drive in hot climates.
Fitment and Mounting
Correct fitment ensures the fan mounts securely, aligns with the radiator, and clears nearby components. A direct-fit assembly reduces installation time and decreases the chance of vibration or rubbing that can damage blades or surrounding parts.
Confirm that mounting points, blade clearance, and electrical connectors match the Ram 3500 layout or can be adapted without cutting or major modifications. Consider whether included brackets or hardware are sufficient for a trouble-free install.
Electrical Compatibility
Electrical compatibility covers voltage, current draw, and how the fan integrates with the truck's control systems. Fans with excessive amperage requirements can strain wiring or trigger fuse issues, while mismatched control methods may conflict with existing temperature sensors or relays.
Check rated voltage and peak current, and verify whether the fan is designed for direct battery feed, relay control, or integration with the vehicles fan controller. Properly matched electrical specs reduce the risk of failures and maintain reliable operation.
Noise Level
Fan noise affects cabin comfort and overall driving experience. Noise is influenced by blade design, motor speed, and housing shape. For many owners, quieter operation at cruising speed and idle is a priority when balancing performance and comfort.
Look for designs that optimize blade pitch and reduce turbulence, and consider measured decibel ratings if available. Understand that higher cooling performance can sometimes mean louder operation, so prioritize according to how often you need peak cooling.
Durability and Environmental Resistance
Durability includes resistance to dust, water, and heat, which are common stressors under the hood. Materials, protective coatings, and sealed electrical components help prevent premature failure in demanding conditions.
Evaluate whether the fan housing is corrosion-resistant and whether the assembly includes safeguards against debris impact. For trucks used off-road or in harsh climates, environmental resistance is a key determinant of long-term value.
FAQ
How do I tell if the cooling fan on my Ram 3500 is failing?
Common indicators include the fan not running when the engine reaches normal operating temperature, intermittent operation, or unusually loud noise during startup. You might also notice overheating during idle or slow-speed driving. Diagnosing usually starts with checking fuses, relays, and electrical connections, then testing the fan motor directly.
Can I replace the Ram 3500 cooling fan myself?
Many owners can perform a cooling fan replacement with basic tools and mechanical experience, especially when the kit is a direct-fit assembly. You should be comfortable disconnecting electrical connectors, removing mounting hardware, and supporting the radiator if needed. If the replacement requires modifications, professional installation is advisable.
Is an electric cooling fan better than a mechanical one for heavy towing?
Electric fans offer the advantage of variable control and reduced parasitic drag since they only run when needed. For towing, an electric fan with sufficient airflow can maintain temperatures more efficiently at low vehicle speeds. The key is choosing a unit with enough cooling capacity and a durable motor suited to extended operation.
What are common causes of a cooling fan not running on startup?
Typical causes include blown fuses, faulty relays, poor ground or power connections, a failed fan motor, or a malfunctioning temperature sensor or control module. Systematic electrical checks can identify whether the issue is power supply, control signal, or the fan itself.
Do I need a fan shroud assembly when replacing the cooling fan?
A shroud helps direct airflow through the radiator and can significantly improve cooling efficiency, especially under low-speed conditions. If the existing shroud is damaged or the replacement fan does not align properly with the radiator, installing a compatible shroud assembly is recommended.
How We Chose the Best Ram 3500 Cooling Fan
We focused exclusively on cooling fans that are compatible with the Ram 3500 platform and that meet common heavy-duty usage demands. Key evaluation criteria included airflow performance measured in CFM or specification-equivalent figures to judge cooling capacity, motor durability and rated lifespan to assess reliability under heavy load, electrical draw and compatibility with the vehicles charging system, physical fitment and mounting points relevant to the Ram 3500 chassis, and noise output during operation to balance comfort with performance. We also looked at construction quality of the fan blades and housing to anticipate longevity in dusty or high-temperature conditions. Products were excluded if they lacked clear fitment information for the Ram 3500, showed poor documentation of motor specs, or had insufficient mounting hardware for direct replacement. We did not include universal-fit units that require extensive modification or vendors without reasonable installation guidance. The resulting shortlist emphasizes direct-fit or near-direct-fit options that match the vehicles electrical and mounting requirements while offering measurable differences in cooling capacity, durability, and noise.
Our full evaluation process is outlined in our review methodology.
Conclusion
When choosing a Ram 3500 cooling fan, prioritize fitment, airflow capacity, and motor durability to match the vehicles typical workload. Balance noise and electrical demand against cooling needs to find the best compromise for daily driving, towing, or heavy-duty use. Remember that correct electrical setup and mounting are as important as raw performance. Focus on options that offer clear fitment information, robust motor specs, and construction suited to the environments where you drive.
