I'm replacing my 02 sensors and I'm wondering what part numbers, how many and where can I get them? Thanks

I've been told there are two then someone else said 4..... I've heard upstream and downstream :cookoo:

UPSTREAM (http://www.1aauto.com/1A/oxygen-sensors/Cadillac/EscaladeESV/ACEOS00002/553142)

DOWNSTREAM (http://www.1aauto.com/1A/oxygen-sensors/Cadillac/Escalade/WKEOS00055/629930)

Also what make should I be looking for? Thanks

There are 2 before the catalytic's and 2 after, so 4 total

Ok and I'm guessing the two before are called upstream

Watch out for the brand of replacement sensor, some aftermarket sensors have a slightly different calibration and will make the engine run slightly richer or leaner, depending on which way they are off. Ran into this with a replacement Bosch Oxygen sensor vs. OEM AC on my GN about 20 years ago. The Bosch ran too lean and caused driveability issues.
