What is a liquid line on a auto ac system?


ORIFICE TUBE AND LOCATION IN VEHICLE

If you are not somewhat mechanically inclined you should let a professional do this as the AC coolant will be released. You will have to re-charge the system upon completion. Here are some quotes from on-line mechanics to give you a better idea what you are looking for. The Orifice tube can be determined as faulty when your AC doesn\'t cool properly in the summer or heat well in the winter. Often you will smell antifreeze inside your car\'s interior.



"It\'s buried pretty good. It\'s in the liquid line that runs along the left inner fender well, under the brake booster. If you look closely at the line, you will see a connection and dimples in the line where the tube is located." Quote from ASE: Wrenchtech Aug 2011.

The liquid line is located in the area of the abs pump.

"The fixed orifice is located in the inlet tube to the evaporator core, this is where the small high pressure AC line from the compressor connects to the tube sticking out of the engine firewall, u will most likely need a special tool to remove it," below is an example of the tool, "don\'t damage the evaporator core by trying to remove the orifice tube without this if it is stuck down in the tube." ---Dennis Weid

The tool comes as a single apparatus or you can get the kit. Here are some examples of manufacturers who make these parts. I have removed the sales information because there are literally hundreds of choices out there including your local parts stores:



Mastercool 92311 Deluxe Orifice Tube Repair Kit This 5 piece universal kit will remove and install any style orifice tube.



Another suggestion comes from Ronnie Bennett Sr.: "The orifice tube will be on the small line joining the evaporator, the ac line will be swelled where the orifice tube is at, you may not see it, but use needle nose pliers to remove it, and to install it."



But I would look at YouTube for a better understanding of what you are looking for, how it works and how to remove and replace it, so try this site to start with and look further. You\'ll be surprised the amount of data available and a video is worth a zillion words.

If you haven\'t seen pictures of the part, this is what it looks like:

Usually the orifice tube is in the lower metal line going to the condenser, possibly behind the grille. The line is bulged out wider where the tube is.

I put in three cans of refridgerant and the ac didn't get cool. Did I put enough in or do I have a leak?


You may have a stopped up orifice tube,feel of the large ac line going into the firewall,see if it is cold,if it is,then the inside door for the temp is not working,but if the ac line is not cold,remove the freon and remove the orifice tube and clean it,or replace it,then charge the system back up.If this was at all helpful,please rate,thank you.
