Motorcraft SW2328 Radiator Fan Switch - OEM Replacement Part for Ford Vehicles | Perfect for Cooling System Repairs & Engine Overheating Prevention

I put this in my 1972 Ford E300 van and it worked immediately. The old original part was 52 years old. If this OEM part lasts as long, then my van will reach 104 years old. Do you think the inexpensive aftermarket stuff works this well? I haven't exactly been following the schedule on coolant changes...
