I would probably get the actual part #, then cross reference it.
You can go to a dealer parts department and give them your VIN#, and they can give you the exact part # for your car.
Looks like 4-pins are rare for some reason, and online auto parts places are vague on whether they are 4 or 3....kinda annoying huh?
Plus make sure it's actually the fan and not the relay. good luck
