Where is the orifice tube on a 2016 Chevy Express?

The orifice tube on a 2016 Chevy Express is located in the air conditioning system. It is part of the expansion valve, which regulates the pressure of the refrigerant that enters the evaporator. The orifice tube is where the liquid refrigerant under pressure converts to a gaseous form. This gaseous refrigerant then absorbs heat from the air passing through the evaporator core and carries it to the condenser where the heat is removed.
Unfortunately, I couldn’t find specific information about the exact location of the orifice tube on a 2016 Chevy Express in the search results. However, it is typically located at the inlet tube to the AC evaporator core on the firewall on the passenger side in most GM cars and trucks . It may be helpful to consult the vehicle’s manual or reach out to a mechanic for more precise information.
If you have any more questions or need further assistance, feel free to ask!

Is the orifice tube on the low side?

Orifice tubes also designate the dividing point between the “high” and “low” sides of the system.

Do orifice tubes go bad?

Any of these problems will require replacement of the expansion valve. An orifice tube is a very simple component with no moving parts. About the only thing that ever goes wrong with them is clogging from debris, which always requires orifice tube replacement.

Is it possible to overfeed a system with a fixed orifice?

If you have an over-sized orifice, you will be overfeeding or flooding the evaporator. If you did not verify that there was some sort of reasonable subcooling value, than you would expect that the unit was overcharged based on the low superheat.

When should I replace my orifice tube?

If the A/C loop is contaminated, the orifice tube will become clogged, and you will need to replace the orifice tube. The orifice tube must always be replaced when another important part of the A/C loop is replaced (compressor, condenser, evaporator, or accumulator)

How can I tell if the orifice tube is clogged?

4 Bad Orifice Tube Symptoms To Watch Out For

1. The Compressor Is Not Able To Pull In The Specified Amount Of Refrigerant.
2. An Intermittent Loss Of Air Conditioning.
3. A Loud Hiss Coming From Inside The A/C System.
4. You Notice Bubbles Within The Sight Glass.
5. Conclusion.

Where is orifice tube located?

The expansion (orifice) tube is located in the evaporator inlet pipe at the orifice connection. The tube restricts the high pressure liquid refrigerant in the liquid line. This restriction meters the refrigerant flow to the evaporator as a low pressure liquid.

Can a orifice tube be cleaned?

Submerge the orifice and nozzle body into an ultrasonic cleaner filled with white vinegar. 5. Run the ultrasonic cleaner for 3–5 minutes or until clean.

Where is the orifice tube located on a 2016 Chevy Silverado?

You can typically find the orifice tube between the condenser and the evaporator on most vehicles. There’s a special orifice tube removal tool that you can use to make the process of uninstalling it easier. If your orifice tube is clogged, make sure to flush your entire A/C system with a specialized cleaner.

Will orifice tube affect AC?

Underperforming AC System
A faulty orifice tube can affect the refrigerant flow and the evaporator won’t be provided with sufficient flow. The lack of flow also means that there won’t be enough refrigerant to absorb the heat that the condenser is providing. A result of all this will be an underperforming AC system.

What will a clogged orifice tube cause?

if you’re refering to the “orifice tube” in an AC system, and if it’s clogged up, coolant flow into the evaporator will be restricted or completely stopped. if the tripping pressure is reached, the compressor will trip or clutch will disengage.
