This procedure covers the removal and replacement of the AC receiver/drier on a 2011-2014 Ford F-150 with 5.0L V8 Coyote engine, including refrigerant recovery, component replacement, and system recharging.

Warnings

Tools required

Parts

• AC Receiver/Drier assembly × 1 — Use OEM specification
• AC O-ring kit (various sizes) × 1 — Use OEM specification
• R-134a refrigerant × 1 — Approximately 1.75-2.25 lbs per system capacity
• PAG 46 oil for AC system × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Allow engine to cool completely if previously running
3. Verify AC system pressure using manifold gauges before starting work
4. Ensure AC recovery machine is ready and has adequate tank capacity
5. Have new receiver/drier and O-ring kit ready but keep sealed until installation

Procedure

1. 1

   Recover AC refrigerant
   Connect AC recovery machine to the low and high side service ports. Follow machine instructions to completely recover all refrigerant from the system. Wait for system pressure to reach zero and stabilize. Record the amount of refrigerant recovered for recharging reference.
2. 2

   Access receiver/drier location
   Open hood and locate the receiver/drier mounted on the passenger side of the engine bay, near the condenser. The receiver/drier is a cylindrical component with two AC line connections at the top. Remove any plastic covers or shields if present to access mounting hardware.
3. 3

   Disconnect AC lines from receiver/drier
   Using appropriate AC line disconnect tools, carefully disconnect both the inlet line (from condenser) and outlet line (to evaporator) from the top of the receiver/drier. Cap all open lines immediately with plugs or tape to prevent moisture and debris entry. Note the orientation and routing of lines for reinstallation.

4. 4

   Remove old receiver/drier
   Remove the mounting bolts securing the receiver/drier to its bracket using appropriate socket. The receiver/drier is typically held by a clamp or bracket with bolts at the base. Support the receiver/drier while removing the final bolt, then carefully lift it out of the mounting location.

5. 5

   Prepare new receiver/drier
   Remove new receiver/drier from packaging only when ready to install. Remove protective caps from the inlet and outlet ports. Add the specified amount of fresh PAG 46 oil to the new receiver/drier as indicated by manufacturer (typically 2-3 oz). Do not leave exposed to atmosphere for more than 15 minutes.
6. 6

   Install O-rings on AC lines
   Remove old O-rings from both AC line fittings using pick or O-ring tool. Inspect line sealing surfaces for damage or scoring. Lubricate new O-rings with fresh PAG 46 oil and install them onto the line fittings, ensuring they seat properly in the O-ring grooves. Do not reuse old O-rings.
7. 7

   Install new receiver/drier
   Position the new receiver/drier in the mounting bracket, ensuring proper orientation with inlet and outlet ports aligned to their respective lines. Install mounting bolts and hand-tighten first, then torque to specification. Verify the receiver/drier is secure and properly seated in the bracket.

8. 8

   Connect AC lines
   Connect the inlet line from the condenser and outlet line to the evaporator to the receiver/drier ports. Push fittings fully onto ports until they bottom out. Hand-tighten the fittings first, then use torque wrench to tighten to specification. Ensure connections are square and not cross-threaded.

9. 9

   Evacuate AC system
   Connect vacuum pump to AC service ports. Run vacuum pump for minimum 30-45 minutes to remove all air and moisture from the system. System should pull down to 29-30 inches of mercury. After evacuation, close valves and monitor vacuum hold for 10 minutes. If vacuum drops significantly, there is a leak that must be addressed.
10. 10

    Recharge AC system
    With system still under vacuum, connect refrigerant source to low side service port. Introduce R-134a refrigerant to match the amount recovered (or system specification shown on underhood label, typically 1.75-2.25 lbs). Charge with engine running and AC on maximum. Monitor pressures using manifold gauges. Do not overcharge the system.
11. 11

    Check for leaks
    With system charged and pressurized, use electronic leak detector or approved leak detection method to check all connections at the receiver/drier, both line fittings, and all surrounding AC components. Pay special attention to the newly installed connections. If any leaks are detected, recover refrigerant, repair leak, and repeat evacuation and recharge process.

Reassembly

1. Reinstall any plastic covers or shields removed for access
2. Verify all AC line connections are properly torqued and leak-free
3. Clean any spilled PAG oil from engine bay surfaces

Verification

• Start engine and turn AC to maximum cold with blower on high
• Allow system to run for 5-10 minutes and verify cold air output from vents (typically 38-42°F at center vent)
• Check AC compressor cycles on and off normally
• Verify low side pressure is 25-35 PSI and high side is 200-250 PSI at idle with ambient temperature around 75-85°F
• Listen for unusual noises from compressor or AC system
• Verify no refrigerant odor or visible oil leaks around receiver/drier connections
• Test AC performance during short test drive to confirm proper operation under load
