• Fan size: measure your radiator core and the available space between the radiator and the engine or bumper. Fans in this range run from 4in up to 19in.
• Push or pull: a pull fan mounts on the engine side of the radiator and draws air through the core. A push fan mounts on the front side and blows air through it. Choose the version that suits where your fan will sit.
• Airflow and power: SPAL listings show rated airflow in CFM for high performance fans and wattage (300W, 500W or 850W) for brushless fans. Compare these against your engine's cooling needs.
• Mounting style: brushless fans come in flush mount and drop-in versions. Check which suits your radiator and shroud.
• Blade type: some 16in SPAL fans are offered with straight, curved or paddle blades.
• Control: brushless fans can be paired with a SPAL variable temperature control sensor. Choose the temperature range that suits your engine.

Always confirm dimensions and specifications against the manufacturer's information before ordering.

A complete thermo fan setup usually needs the fan, a suitable wiring harness or relay harness, mounting hardware, and a temperature sensor or switch to control it. SPAL brushless fans are supplied with a jumper harness. Harness adapters, extra jumper harnesses, brackets, strap mounts, mounting pins and the VA18 shroud gasket are available separately in this collection.

Installation by a professional is recommended, as thermo fans involve both electrical wiring and changes to your cooling system.
