I am changing my compressor and accumulator on my 03 Dodge Ram 4.7l but I can’t seem to find the orrifice tube location. Please help ---

You might have to replace the line itself. ![image](https://global.discourse-cdn.com/cartalk/original/3X/d/4/d40278f980dfab2aac71ffee03e3eb41a398c7a8.png) Tester ---

It’s the high side line from the condenser to the evaporator… Tester ---

The orifice tube is located in the liquid line, number 14 in the diagram. ![image](https://global.discourse-cdn.com/cartalk/original/3X/0/7/071f78c628bdbd5f9aaf931890fe0e78da00487d.png) ---

If there’s no fitting in the line to replace it, then yes. Tester ---

Found a fitting behind my intake filter. I took it apart but there was nothing inside the tubes ---

Was the compressor replaced because of a clutch issue, leaking, or was it flat trashed? If trashed that leads to flushing the system out or a new orifice tube will plug up along with contaminating the new accumulator and compressor. ---

It’s been probably 30 years but I distinctly remember the mechanic pulling that device out and replacing it. Not the whole tube but just the device. I thought it was on top where the line went in, You might order a new line just to find out that part wasn’t included. But that was on my Olds 88. ---

The clutch was bad. I will have it flushed and recharged. But can’t seem to find where to put the orrifice tube ---

Look for a crimp or dimples in the liquid line, that is where the orifice tube is held. ---

The orifice tube is somewhere between the condenser and evaporator. I’ve seem them located at the connection at the condenser and at the connection at the evaporator, and in between. Tester ---

I see the dimples but nothings inside there and my orifice tube doesn’t fit in there. ---
