What the AI looks for in Engine Radiator Fan Motors

Motor vs complete assembly: Decide whether you need only the motor or the full fan, shroud and motor assembly; on many vehicles the assembly is the practical replacement Bare motors require removing the fan blade and matching shaft size, while assemblies swap more simply.
Connector and control: Match the connector, single or dual speed design, resistor or PWM control module Many modern fans are PWM-controlled with a built-in module, and a mismatched control type leaves the fan inoperative or stuck on high.
Shaft and mounting: Match shaft diameter, length and the motor mount bolt pattern A motor that mounts slightly off-center causes blade contact or vibration.
Diagnose first: Check fuse, relay, temperature sensor and control module before replacing the motor Relays and sensors fail more often than motors and cost less.

Dorman: Broad range of OE-style fan assemblies and motors.
TYC: Wide-coverage aftermarket fan assemblies.
Four Seasons: Climate control specialist offering radiator and condenser fan motors.
Bosch: OE fan motor supplier for many European vehicles.
Spal: Universal and performance electric fans for custom builds.
Denso: OE fan motor and assembly supplier for many Japanese vehicles.

Replacing the motor without checking the relay, fuse and sensor first.
Universal fans adapted onto stock vehicles without proper shroud and control wiring.
Assemblies that use a different control type than your vehicle.

This often points to a failed temperature sensor, stuck relay or a control module or wiring mismatch rather than a bad fan.
