Title: Location of low pressure port (for adding R134a) to dash air
Post by: JohnRobinson on October 01, 2018, 08:59:07 PM

I am seeking input on where to look for the low pressure port on a 2005 Beaver Monterey. Thanks!

Doesn’t seem to be a consensus.  Some  models have the charge port adjacent to the compressor on the engine, and others have the charger ports near The back of the dash a/c on the passenger side of the firewall above and to the left of the generator.  Hint:   Buy the big can if your low.  You’re filling lines that run the length of the coach in either configuration.

Our A/C filling port is straight up above the center of the generator.  I slide the generator out about a foot and reach upwards about the length of my forearm.  I found it by using a mirror and flashlight.

One of two locations either next to the compressor or above the generator on the firewall.

I have the same coach as you, and mine are about 10 inches apart on the top of the compressor in the engine compartment. The first time I looked for the them, the high was easy to find, but the low, with a black cap, was buried under some hoses.

Thank you to those who replied. Your comments emboldened my search and I did find the port near the compressor. The location was so tight that I could not use the consumer product to re-charge - the fitting was too bulky. I have an appointment at a local place tomorrow. From the sounds of it, they will do it right by evacuating the system, weighing, then reloading.

I had to loosen the air cleaner hose clamps and twist the tubing up as far as possible then retighten the clamps. I know not every configuration is like mine but that's what I had to do to get the gauges on.
