Warnings

Tools required

Parts

• AC Condenser × 1 — Use OEM specification
• AC Line O-ring Kit × 1 — Use OEM specification
• AC Refrigerant R-134a × 1 — Approximately 1.5 lbs
• PAG 46 Compressor Oil × 1 — 50ml

Preparation

1. Park vehicle on level ground and engage parking brake
2. Allow engine to cool completely if recently operated
3. Raise vehicle on lift or secure on jack stands at manufacturer-specified lift points
4. Remove front wheels for easier access to bumper mounting hardware
5. Remove engine undertray and wheel well liners
6. Disconnect negative battery terminal and wait 15 minutes for airbag system discharge
7. Photograph bumper mounting points and wiring connections for reference during reassembly

Procedure

1. 1

   Recover AC refrigerant
   Connect AC recovery machine to high and low side service ports. Follow machine manufacturer instructions to fully recover all refrigerant from the system. Record the amount of refrigerant and oil recovered for recharge reference. Verify system pressure reaches vacuum before proceeding.
   ⚠️Only EPA-certified technicians may perform refrigerant recovery. Ensure recovery machine is properly calibrated and maintained.
2. 2

   Remove front grille and bumper covers
   Remove upper grille by releasing clips along top edge. Remove foglamp bezels and lower grille sections. Disconnect any wiring harnesses for parking sensors, foglamps, or daytime running lights. Label all connectors for proper reconnection.
   ⚠Grille trident emblem is fragile and expensive. Handle with care during removal.
3. 3

   Disconnect AC lines from condenser
   Locate the high and low side AC line connections at the condenser. Use appropriate flare nut wrenches to carefully loosen and disconnect both AC lines from the condenser. Cap all open fittings immediately to prevent moisture and debris contamination. Remove and discard old O-rings from the line fittings.
   ⚠Even after recovery, residual refrigerant or oil may be present. Have shop towels ready to catch any drips.

4. 4

   Remove front bumper assembly
   Remove T30 Torx bolts securing bumper to fender liners (2 per side). Remove 10mm bolts along top bumper rail mounting points. Remove lower mounting bolts underneath vehicle. With assistance, carefully pull bumper forward and away from vehicle. Place on protected surface to avoid scratching.
   ⚠Bumper is large and awkward. Use a second person to avoid dropping or bending the assembly.
5. 5

   Remove auxiliary cooling fans if equipped
   If condenser is equipped with dedicated auxiliary cooling fans, disconnect electrical connectors. Remove mounting bolts securing fan assembly to condenser or radiator support. Carefully lift fan assembly out of engine bay.
6. 6

   Remove condenser mounting bolts
   Locate condenser mounting bolts at the top and bottom of the condenser assembly. There are typically 4-6 mounting points. Remove all bolts securing condenser to radiator support and crossmember. Note the location of any spacers or insulators for reinstallation.

7. 7

   Remove condenser from vehicle
   Carefully tilt the top of the condenser forward and lift upward to clear mounting tabs. Maneuver condenser out from between radiator and bumper support structure. Inspect radiator fins for damage during removal and straighten any bent sections with a fin comb.
   ⚠Condenser fins are extremely fragile. Avoid contact with hard surfaces and be mindful of radiator behind it.
8. 8

   Prepare new condenser
   Remove protective caps from new condenser fittings. Install new O-rings on condenser inlet and outlet ports, lubricating lightly with clean PAG 46 oil. If new condenser does not come pre-charged with oil, add the manufacturer-specified amount (typically 50ml PAG 46) through one of the ports before installation.
9. 9

   Install new condenser
   Carefully maneuver new condenser into position between radiator and bumper support. Align mounting holes with radiator support brackets. Install condenser mounting bolts with any spacers or insulators in their original positions. Torque mounting bolts to specification in a cross pattern to ensure even seating.

10. 10

    Reinstall auxiliary cooling fans
    If removed, position auxiliary fan assembly back onto condenser or radiator support. Secure with mounting bolts. Reconnect electrical connectors ensuring positive engagement.
11. 11

    Connect AC lines to new condenser
    Install new O-rings on AC line fittings, lubricating lightly with clean PAG 46 oil. Hand-thread AC line fittings onto condenser ports to avoid cross-threading. Use flare nut wrenches to tighten fittings to specification. Do not over-tighten as this can damage O-rings or aluminum threads.
    ⚠Critical seal point. Improper torque or damaged O-rings will cause refrigerant leaks.

12. 12

    Reinstall front bumper assembly
    With assistance, align bumper assembly with mounting points on vehicle. Install all mounting bolts at fender liners, top rail, and lower mounts. Reconnect all electrical connectors for sensors and lighting. Verify proper fitment and panel gaps before fully tightening all fasteners.
13. 13

    Reinstall grilles and trim
    Reinstall lower grille sections and foglamp bezels. Install upper grille ensuring all clips are properly seated. Verify trident emblem is secure. Install wheel well liners and undertray.
14. 14

    Evacuate and recharge AC system
    Connect AC service machine to high and low side ports. Perform vacuum test by pulling system down to 29+ inches Hg and holding for minimum 30 minutes to verify no leaks and ensure system is moisture-free. If vacuum holds, recharge system with R-134a to factory specification (approximately 1.5 lbs total). Add UV leak detection dye if desired.
    ⚠If system fails to hold vacuum, there is a leak that must be found and corrected before charging with refrigerant.

Reassembly

1. Reinstall front wheels and torque lug nuts to specification (110 Nm)
2. Reconnect battery negative terminal
3. Lower vehicle from lift
4. Verify all trim pieces and panels are properly secured
5. Check that all lights and sensors are functioning properly

Verification

• Start engine and turn AC to maximum cold setting with fan on high
• Allow system to run for 10 minutes and verify condenser cooling fans activate
• Check that center vent temperature reaches 40-45°F within 5 minutes in ambient temperatures above 70°F
• Inspect all AC line connections for signs of oil residue indicating leaks
• Verify compressor cycles on and off normally and does not run continuously
• Check refrigerant pressures with gauges: low side should be 25-45 psi, high side 200-250 psi at idle in 75°F ambient
• Perform visual inspection around condenser area with UV light if dye was added
• Verify no unusual noises from AC system operation
• Test drive vehicle and confirm AC performance is consistent and cooling is adequate
