12″ Slim Pull Electric Radiator Fan Kit

The 12″ Slim Pull Electric Radiator Fan from BLACKHORSE-RACING Store offers a compact, high-performance option for engine bays with limited clearance. Features include 10 blades, 80W power, and a maximum of 800 CFM at up to 2000 RPM. A slim profile enhances clearance, and the unit is designed for long service life with heat and corrosion resistance. Best for smaller engines or tight installations where airflow is needed without sacrificing space. Caution: assembly weight and mounting compatibility should be matched to your vehicle’s mounting points.
12″ Universal Slim Push/Pull Fan (2-Pack)

This package provides two 12″ high-performance fans designed for reversible use. The kit supports push or pull configurations with identical specs: 12V, 80W, 12.44″ diameter, 2.36″ thick, and ≥800 CFM at about 2000 RPM. Best for dual-fan setups or projects needing flexible airflow direction. Caution: ensure wiring and relays accommodate two fans and the vehicle’s electrical load.
Dorman 620-225 Engine Cooling Fan Assembly

The Dorman 620-225 assembly is positioned as a precise replacement for select Honda models, designed to match the stock radiator fan assembly’s fit and performance. It comes as a complete package with materials and components aligned with OEM standards. Best for owners seeking a straightforward, ready-to-install replacement that mirrors factory cooling behavior. Caution: verify compatibility with your specific vehicle year and model before purchase.
BLACKHORSE-RACING 16″ Electric Radiator Fan Kit

This 16″ high-capacity kit includes a 10-blade, 12V fan with a high torque motor and a thermostat. The kit supports up to 1000 CFM and up to 2000 RPM, with a 3/8″ NPT brass probe and 1/2″ NPT adapter for thermostat control. Best for vehicles that experience higher operating temperatures or require more aggressive cooling. Caution: thermostat kit adds wiring complexity and requires proper installation to avoid false temperature readings.
labwork Radiator Cooling Fan Replacement

The labwork replacement is designed for Chevrolet Malibu 2004-2012, Pontiac G6 2005-2010, and Saturn Aura 2008-2009. It emphasizes high-performance motor operation, durability, and efficient engine temperature reduction with multi-fan blade design. Best for model-year specific upgrades where the exact part match is essential. Caution: ensure the replacement part aligns with your vehicle’s exact year and model to avoid fit issues.
Buying Guide: How To Choose The Right Radiator Cooling Fan
What cooling needs does your vehicle have? If space is tight, a slim pull design or a reversible push/pull setup offers flexibility. For hot climates or high-load driving, a larger 16″ fan with a thermostat can provide more reliable cooling under heavy use. Consider whether you need a complete OEM-style replacement versus a standalone fan that you mount into an existing assembly. Evaluate the maximum CFM and RPM to ensure adequate airflow without overloading the electrical system.
How easy is installation? Look for mounting brackets, tie straps, and compatibility with your radiator. A fully integrated thermostat kit helps manage engine temperatures automatically, but it requires proper wiring and sensor placement. If you plan a dual-fan setup, verify current draw and relay capacity to avoid electrical issues. Finally, confirm that the part matches your vehicle’s year, make, and model for the best fit and long-term reliability.
What are practical limitations? Slim fans save space but may deliver lower CFM than larger units, so assess whether your cooling needs require higher airflow. Thermostat kits add complexity; ensure you can route wires cleanly and protect them from heat exposure. Replacement assemblies may be model-specific, so verify compatibility before purchase.
Frequently Asked Questions
- What is CFM in radiator fans? CFM stands for cubic feet per minute and measures the volume of air the fan can move. Higher CFM generally means better cooling.
- Do I need a thermostat with a radiator fan? A thermostat helps regulate cooling by turning the fan on and off at set temperatures, improving engine temperature management.
- Can I use a fan as both pull and push? Yes, some models are reversible and can operate as a puller or pusher, providing installation flexibility.
- Is a higher RPM always better? Not always. Higher RPM increases airflow but also noise and electrical load; choose RPM that matches your cooling needs and vehicle capabilities.
- How do I know if a replacement fan fits my car? Check the vehicle’s year, make, model, and part number compatibility with the replacement kit or OEM-style assembly.
- What should I watch for with dual-fan kits? Ensure your vehicle’s electrical system can support the combined current draw and that wiring/relays are correctly specified.
