Engine Coolant Sensor Part Number 5.3 liter

[Cheverado]

Anybody have the GM part number for this? all of the internet research that ive done yield about a dozen different AC Delco part numbers and few 8 digit GM part numbers. Am trying to avoid driving down to the stealership. Prior to the original sensor (the one with the white plastic connector) failing, my engine temp was typically around 200 degrees. I replaced it with an AC Delco 213-4514 (has black plastic connector) (per Amazon correct fitment) and my temp doesnt get over 180 degrees.  What temps are yall seeing please?

I run at 210-214 at operating temp even in -15 degree temps.

According to Rockauto you need 2134333, which has a white connector

Did you not look at Rockauto first?  Never trust Amazon's part checker

Well after going to the store yesterday I noticed the temp fluctuating. Turns out the problem was the thermostat. Comes up to temp and stays there now.
