Does anyb ody know where the A/C charge port is 2000 GMC 3500 Savana Short Bus

[Tedd]

I KNOW I've seen the a/c charge port ... I just can't remember where. I check my manuals and did a google search ... no luck.

It's the Thermo King a/c unit ... skirt mounted condenser, the evaporator is ceiling mounted over the rear escape door. Compressor is mounted on the 6.5 diesel and doesn’t look like anything special.

Anybody got any Ideas?

Convenient location...

thats the typical location for an afternarket unit... if the unit is tied into the factory dashboard air (one comporessor for both).. you will want to measure pressures and charge at the factory dashboard A/C ports..

if its a separate system then you can use the chassis rail charge port...

you will want to take your saturation temperature reading from thje evaporator inlet just past the TxV on the aux unit..

if its a tie in to the factory air its tougher to get a good saturation temperature reading unless its the older system where the evaporator inlet is past the orifice or TxV..

whatever you do dont over-charge a system running with TxV... and the TxV will make gauge charging a chore unless yopu have the PT chart handy and saturation temperature readings...

be sure to clean your condensor coils on both systems before charging..

also remember A/C units DO NOT CONSUME FREON.. so if its empty.. it leaked out somewhere...
