Why is an orifice tube instead of an accumulator?
Why is an orifice tube instead of an accumulator?
Some vehicles use an AC accumulator orifice tube while other vehicles include an expansion valve instead of the orifice tube and a receiver-drier instead of the accumulator. The accumulator allows the moisture to enter the system when it becomes exposed to the atmosphere.
Where is the accumulator located in an AC system?
The accumulator has a desiccant to consume moisture. It is located on the “suction” or “low-pressure side” of the AC system, between the evaporator and the compressor.
Where does liquid refrigerant go in an accumulator?
Any excess liquid refrigerant or water droplets that enter the accumulator flow to the bottom of the accumulator; whereas, the vapor refrigerant passes through the desiccant before flowing out of the accumulator. The AC system, where the accumulator is also included, uses an orifice tube.

When to flush a clogged orifice tube?
When the cause has been found, a system flush will be required, and the component must be replaced or the excess debris will re-clog and damage the new orifice tube. Both the clogged orifice tube and the accumulator must be replaced when debris is found in the system.

Where is the orifice tube on my GMC?
The orifice tube is “in-line”. Not sure on 2007, but on my 2002, passenger fender where line breaks apart. (2 lines connected together with “nuts”). You can usually spot where the orifice is by looking for the slightly enlarged diameter of the line near the connection of the 2 lines.
Is the AC accumulator or receiver drier interchangeable?
To keep moisture from causing problems, your vehicle’s air conditioning system has either an accumulator or a receiver-drier. It will only have one, not the other, and they’re not interchangeable. If your vehicle’s AC system has an accumulator, it is likely to be the last component the refrigerant passes through…
How do you replace an air conditioner receiver drier?
Step 1: Measure the amount of oil in the receiver/drier. Measure the amount of oil in the old receiver/drier by pouring it into a graduated glass. If oil has leaked out of the system, use the manufacturer’s recommended amount to refill the receiver/drier. Step 2: Add oil to the receiver/drier.
Where is the a / C receiver / drier located?
The receiver/drier is located between the located on the high-pressure side of the A/C system between the condenser and evaporator. Step 1: Have the refrigerant recovered by a professional. Before the receiver/drier can be replace, the A/C refrigerant must be removed from the system.
