How do you replace an air conditioner expansion line?
Smear some refrigerant oil on the o rings and insert the new orifice tube into the line. Observe the direction, it’s easy to put it in backwards. The new orifice tube should have an arrow on it that should go in pointing toward the evaporator. Put new O rings on the line and re-connect the line.
Do you need to change the expansion valve on an AC unit?
Also, when changing the compressor, replacement of the expansion valve is usually a requirement for warranty coverage of the new compressor. Remove or discharge any remaining refrigerant from the AC system.
How do you know if an air conditioner expansion valve is recoverable?
Step 1: Identify the refrigerant. Using the service manual, locate the low pressure fitting of the two AC service fittings on the car and connect the refrigerant identifier to the car. The refrigerant identifier will take a small sample of the refrigerant in the system and tell you if it is recoverable or not.
Where is the expansion valve on my car?
If you don’t find the expansion valve under the panel, you’ll have to remove the panels under the dashboard and look for it on the other side. Step 2: Remove the expansion valve.

Why does my air conditioner have an expansion valve?
If your air conditioning (AC) has been less than helpful this summer, it may be the expansion valve (also known as an orifice tube). AC expansion valves regulate the flow of refrigerant through the AC system and if the valves fails they can cause problems with the whole system.
Why do I need to replace my expansion valve in my car?
AC expansion valves regulate the flow of refrigerant through the AC system and if the valves fails they can cause problems with the whole system. Diagnosing your car’s air conditioning system may reveal that your expansion valve or the orifice tube needs to be replaced.
When to replace the O rings on an air conditioner?
Step 3: Replace the O-rings. Whenever an air conditioning line is disconnected, the O rings should be replaced with new ones. O-rings should be soaked in the appropriate refrigerant oil before use.

Where is the a / C expansion valve located in a car?
The A/C expansion valve is found within the air conditioning system of a vehicle. The purpose of the valve is to manage how much refrigerant liquid can flow throughout this system.
Is it necessary to replace an air conditioning expansion valve?
Replacing an expansion valve requires special equipment and there are a number of laws regarding handling refrigerants. So it is strongly recommended that you engage a professional to do this job.
