This procedure covers the removal and replacement of the AC receiver/drier on a 2012-2017 Toyota Camry with 2.5L I4 engine, including refrigerant recovery, line disconnection, and system recharge.

Warnings

Tools required

Parts

• AC receiver/drier assembly × 1 — 88710-06100 or aftermarket equivalent
• AC line O-rings × 4 — Use OEM specification for refrigerant lines
• R-134a refrigerant × 1 — Approximately 1.5 lbs total system capacity

Preparation

1. Verify AC system refrigerant type is R-134a (labeled on underhood sticker)
2. Ensure engine is completely cold before beginning work
3. Position vehicle on level ground and engage parking brake
4. Gather all replacement parts and verify receiver/drier is correct for vehicle year
5. Connect AC recovery machine to service ports on low and high pressure sides
6. Open vehicle windows to prevent pressure buildup during refrigerant recovery

Procedure

1. 1

   Recover AC refrigerant
   Using certified AC recovery equipment, connect to both high and low pressure service ports. Follow recovery machine instructions to completely evacuate all refrigerant from the system. Record the amount of refrigerant recovered for recharge reference. Ensure recovery is complete before proceeding (typically 15-20 minutes).
   ⚠️Never loosen AC line fittings with refrigerant still in the system. System pressure can exceed 300 psi.
2. 2

   Locate receiver/drier assembly
   The receiver/drier is mounted on the front right side of the engine bay, attached to the condenser or nearby frame rail. It is a cylindrical component approximately 8-10 inches tall with two refrigerant lines connected at the top. Identify the inlet line from the condenser and the outlet line to the evaporator.
3. 3

   Disconnect refrigerant lines
   Using a flare nut wrench to prevent rounding, loosen both refrigerant line connections at the receiver/drier. The connections use 12mm and 14mm flare nuts depending on line size. Once loosened, remove lines completely and immediately cap open ports with plugs or tape to prevent moisture entry and contamination. Inspect line ends for damage or excessive wear.
   ⚠A small amount of residual refrigerant or oil may escape when lines are disconnected. Work in a well-ventilated area.
4. 4

   Remove old O-rings
   Remove and discard all O-rings from the disconnected refrigerant line fittings. Use a pick tool if necessary, being careful not to scratch sealing surfaces on the line fittings. Inspect fitting faces for damage, grooves, or corrosion. Clean fitting surfaces with a lint-free cloth.
5. 5

   Remove receiver/drier mounting
   Remove the mounting bolt(s) securing the receiver/drier to its bracket. The drier typically uses one or two 10mm bolts. Support the receiver/drier while removing the final bolt to prevent it from falling.
   ⚠The receiver/drier contains desiccant material that may rattle. This is normal.

6. 6

   Remove old receiver/drier
   Carefully remove the receiver/drier assembly from the vehicle. Note the orientation and any routing considerations for the replacement unit. Drain any residual oil from the old unit into a measuring container to determine how much oil was in the system. Dispose of the old receiver/drier according to local regulations.
7. 7

   Prepare new receiver/drier
   Remove the new receiver/drier from its packaging only when ready to install. Check that shipping caps are in place on both ports. Add the appropriate amount of fresh PAG oil (typically 1-2 oz) to the new receiver/drier before installation to replace what was in the old unit. Most new units come pre-charged with oil; consult manufacturer instructions.
   ⚠Minimize the time the new receiver/drier is exposed to atmosphere. Desiccant begins absorbing moisture immediately upon exposure.
8. 8

   Install new receiver/drier
   Remove shipping caps from the new receiver/drier and immediately position it in the mounting bracket in the same orientation as the original. Thread in the mounting bolt(s) and torque to specification. Ensure the unit is securely mounted and properly oriented for line connections.

9. 9

   Install new O-rings with PAG oil
   Install new O-rings on all refrigerant line fittings. Coat each new O-ring with a thin film of fresh PAG oil before installation to ensure proper sealing and prevent damage during connection. Verify O-rings are properly seated in their grooves and not twisted or pinched.
   ⚠Do not use petroleum-based lubricants on AC O-rings. Use only PAG oil or approved AC system lubricant.
10. 10

    Reconnect refrigerant lines
    Connect both refrigerant lines to the new receiver/drier. Hand-tighten the flare nut fittings first to ensure proper threading, then use a flare nut wrench and torque wrench to tighten to specification. Do not over-tighten as this can damage the flare seats and cause leaks.

11. 11

    Evacuate AC system
    Connect a vacuum pump to the AC system service ports. Pull a vacuum on the system for a minimum of 30 minutes, preferably 45-60 minutes. The system should reach at least 29 inches of mercury vacuum. After evacuation, close valves and monitor for 10 minutes to verify the system holds vacuum, indicating no leaks.
    ⚠If the system does not hold vacuum, there is a leak. Do not proceed with recharge until leak is found and repaired.
12. 12

    Recharge AC system
    With the system under vacuum, introduce the correct amount of R-134a refrigerant (approximately 1.4-1.5 lbs for this system, verify on underhood label). Charge through the low-side service port with the engine running and AC on maximum. Monitor system pressures with manifold gauges. Add refrigerant slowly to prevent compressor damage from liquid slugging.
13. 13

    Leak check all connections
    With the system charged and pressurized, use an electronic leak detector or UV light (if UV dye was added) to check all connections at the receiver/drier for leaks. Pay special attention to the line fittings just reconnected. Check for oily residue or bubbles indicating refrigerant escape.

Reassembly

1. Verify all refrigerant line connections are tight and properly torqued
2. Ensure receiver/drier mounting bolts are secure
3. Confirm no tools or parts are left in the engine bay
4. Close hood and clean work area

Verification

• Start engine and turn AC to maximum cold with fan on high
• Allow system to run for 5-10 minutes and verify cold air output from vents
• Check that AC compressor cycles on and off normally
• Verify system pressures are within specification: low side 25-40 psi, high side 200-275 psi at idle (ambient dependent)
• Listen for unusual noises from the AC compressor or lines
• Re-check all connections for leaks after system has been running
• Monitor AC performance over the next few days to ensure consistent operation
