How to Replace an Air Conditioner Receiver Drier

ac receiver dryer

The receiver/drier is designed to store and dry A/C refrigerant. There is a desiccant inside that absorbs moisture from the refrigerant. Receiver/driers are used in expansion valve equipped A/C systems.

It is the job of the receiver/drier to protect the rest of the A/C system against moisture damage. The desiccant bag can only hold a finite amount of moisture. If too much water gets into the system, the receiver/drier should be replaced. The receiver/drier should also be replaced if it leaks, is clogged or the A/C compressor is being replaced (as a preventive measure).

Signs of a failed receiver/drier include desiccant in the A/C system, moisture in the system, ice build up on the receiver/drier or a temperature drop between the unit inlet and outlet.

Part 1 of 3: Locate the receiver/drier

In order to safely and efficiently replace your A/C receiver/drier you need a couple of basic tools:

locating the receiver/drier

Step 1: Locate the receiver/drier. The receiver/drier is located between the located on the high-pressure side of the A/C system between the condenser and evaporator.

Part 2 of 3: Remove the receiver/drier

Step 5: Remove the receiver/drier. Remove any fasteners securing the receiver/drier and remove it from the vehicle.

Part 2 of 3: Installing the new 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. Add the correct amount of oil, as determined from the previous step.

Most A/C systems use PAG oil, but a few use Polyol Glycol, so it’s important to determine which is used in your vehicle.

Step 3: Replace the pressure line o-rings. Remove the oil o-rings from the A/C pressure lines with a small screwdriver.

Lubricate the new o-rings with refrigerant oil and slide them into place.
