I replaced my radiator and accidentally broke the old one. Both coolant sensors are under $10 at Rockauto. The fan switch is $75! It looks similar to the other sensors, 2 wires, etc.
Can you please clarify? You broke the old radiator? Or you broke an electrical component of the radiator fan?
Why not just unscrew one off of another Prius at the junkyard I've got several here and talking about the snap switch on the radiator that lets power move to the fans when it's open or something this is for the radiator fans?
