ACDelcoGM Original Equipment 213-3520 (12585546) Engine Crankshaft Position Sensor

Its perfect

This sensor is supposed to be the gray 58x for the Gen 4 LS. I received 2 of these in a row that contained the black sensor for the Gen 3 24x LS. They had the correct part number for a 58x on the package, but the package contained the 24x sensor.

Its the cheapest price but orginal AC delco , i had a problem with an oil leak that came from above the starter and turns out its this sensor the o ring goes bad but they want $11 for the o ring so since your up their your better off replacing the part aswell, For 2007 tahoe or similar you have to unbolt the starter also the 2007 Chevy tahoe did not have to take to a dealer for relearn it did it itself some vehicals may require a relearn process.

Good product but the truck this was for never buy 2007 cadillac escalade stay away from them

You will more than likely need to remove your starter to change this, just a heads up. Not bad though if you’re not a stranger to automotive mechanical work.
