Review on ACDelco Professional 213-4761 Engine Crankshaft Position Sensor: Performance at its Finest by Johnny Wheat

The 213-4761 AcDelco part I received does not have the seals or instructions shown on the Revain product image. I sent the sensor back but there was no replacement either. I contacted Delco and found they have a sensor in their catalog with seals and instructions, but the part is no longer supplied in this form. And GM can sell you gaskets through the dealer for about $10. It was also revealed that Standard Motor Parts is Delco's current parts supplier. If you buy a PC123 standard engine part that is an exact match for a Delco part, it will come with gaskets and instructions. This is about half the cost of an ACDelco marked part. Made in Mexico, at least not in China!
