Will this bolt directly to my factory mounting points?

Yes. This assembly uses the factory radiator fan locations — no drilling, no adapter brackets, no welding. Install follows the same points as the original.

Do I need to drain the radiator to swap this out?

Refer to your vehicle's service manual for the complete removal procedure. Most radiator fan assemblies can be accessed without full system drain, but always verify before you start.

What if the fan doesn't engage or run after installation?

Confirm the wiring harness is fully seated and the coolant temperature sensor is functioning. If the original system worked correctly, the new assembly should trigger the same way — check connections first.
