Where is the orifice valve located?

One of the many parts that can fail within your vehicle’s air conditioning, is the orifice tube. This tube is also known as the expansion tube, and is located within the tube between the condenser and the evaporator. It has 1 side that is a little smaller than the other, to supply more pressure.

How do I know if my orifice tube is clogged?

Symptoms of a Bad or Failing Expansion Valve (Orifice Tube)

  1. AC system performing worse than usual and blowing warm air. One of the first symptoms of a problem with the AC expansion valve or orifice tube is an underperforming AC system.
  2. Frost on AC evaporator or coming from the vents.
  3. AC compressor constantly running.

Where is the orifice tube on a?

Where is the orifice tube on a 2001 Jeep Wrangler?

Jeep Wrangler Aftermarket liquid line and orifice tube. This is an aluminum line that runs along the passenger side fender well; it connects the condenser to the evaporator. The orifice tube is included in the line, as well as a low side charge port. The line has orings already installed.

What is the difference between an expansion valve and an orifice tube?

Expansion valves are an active device, they regulate the flow of refrigerant to the evaporator depending on evaporator temperature. An orifice tube is just a fixed nozzle that pisses refrigerant into the evaporator without any sort of feedback.

What causes orifice tube blockage?

A clogged orifice tube is typically caused by compressor failure. When this happens, little pieces of metal and aluminum shrapnel will be found in the tube’s screen filter. If the filter’s filled with white or brownish debris, the desiccant bag in the accumulator has broken, sending desiccant throughout the system.

What are the signs of a bad expansion valve?

Symptoms of a bad expansion valve

  • Car AC system isn’t cooling enough or won’t cool at all.
  • High side pressure is high.
  • Air coming from vents is frosty.
  • AC blows cold, then hot.
  • AC kicks on and then immediately kicks off.
  • Airflow drops dramatically from vents.

Can you change the orifice tube?

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. Put new O rings on the line and re-connect the line.

Do all vehicles have an orifice tube?

The expansion valve does contain moving parts, including a self-contained meter system to regulate the refrigerant flow from the compressor to the evaporator. Most modern vehicles use either an orifice tube or an expansion valve depending on your make and model.
