Default Locating the low side port on a 2006 Chevy Tahoe Z71

Good day,

I am looking for the low side port on a 2006 Chevy Tahoe Z71. Looking to put AC Pro sealant and Freon in to seal any leaks and recharge my AC. Can someone tell me where this port is. I have had two mechanics look for this port and it is no where around where most of the ports are located. Thank you in advance!

iirc its on the top of the accumulator.


sealant is not the best idea to put into your ac system. It forms a seal when exposed to the air...if you do not vacuum out the system before filling, it may form gunk in the system. 2ndly, no shop will hook there machine up to your truck as the sealant will wreck their ac machine...so if the sealant doesn't work and you need to open the ac lines on your truck to fix something...gunk forms everywhere.

finding and fixing the leak, worst case scenario just fill it temporarily but without sealant.
