Complete replacement of the AC condenser on a 2016-2024 Hyundai Tucson 2.5L I4 AWD, including refrigerant recovery, condenser removal, and system recharge.

Warnings

Tools required

Parts

• AC Condenser × 1 — Use OEM specification for 2.5L AWD model
• AC line O-rings × 1 — Various sizes, typically 4-6 required
• PAG 46 compressor oil × 1 — 50-60ml typically required
• R-134a refrigerant × 1 — System capacity varies, see underhood label
• Condenser mounting grommets × 2 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge
3. Verify refrigerant type on underhood AC specification label
4. Use certified AC recovery machine to fully recover refrigerant from system and measure oil recovered
5. Remove engine splash shield and front bumper cover for access (requires removing multiple clips and screws)
6. Allow engine to cool completely if recently operated

Procedure

1. 1

   Remove radiator grille and upper cover
   Remove the front grille assembly by releasing retaining clips and removing fasteners. Remove the upper radiator cover panel to access the condenser mounting area. On 2022+ models, some trim pieces are integrated and require careful prying to avoid breaking clips.
2. 2

   Disconnect AC lines from condenser
   Using line wrenches, carefully disconnect the high-pressure and low-pressure AC lines from the condenser inlet and outlet. Cap all open fittings immediately to prevent moisture and debris entry. Remove and discard old O-rings from fittings. Note the routing and positions of any mounting brackets.
   ⚠Ensure refrigerant is fully recovered before loosening line fittings. Even small amounts of residual pressure can spray oil.

3. 3

   Remove cooling fan assembly
   Disconnect electrical connector from cooling fan motor. Remove the fan shroud mounting bolts securing the fan assembly to the radiator. Carefully lift the fan assembly up and out, being careful not to damage radiator fins or fan blades. On AWD models, note there may be dual fans.
4. 4

   Disconnect auxiliary transmission cooler lines if equipped
   If the condenser has integrated transmission cooler lines (common on AWD models), carefully disconnect the cooler line fittings using a line wrench. Have a drain pan ready as some ATF will drain. Cap the lines to prevent contamination.
   ℹ️Not all 2.5L AWD models have transmission cooler integrated into condenser. Verify your specific configuration before proceeding.
5. 5

   Remove condenser mounting bolts
   Remove the upper condenser mounting bolts that secure the condenser to the radiator support. There are typically 2-4 bolts depending on model year. Note the position of any rubber isolation grommets for reinstallation.

6. 6

   Remove condenser from vehicle
   Carefully tilt the top of the condenser toward the engine while lifting it up and out of the lower mounting brackets. Work slowly to avoid damaging the radiator fins or condenser fins. The condenser may need to be angled to clear the radiator support structure. Measure and record any oil drained from old condenser.
   ⚠Condenser fins are very delicate and easily damaged. Take care when removing to avoid bending fins or contacting radiator.
7. 7

   Prepare new condenser
   Remove shipping caps from new condenser. Add the appropriate amount of fresh PAG 46 oil to the new condenser: total amount should equal oil drained from old condenser plus manufacturer's specification for new condenser (typically 20-30ml). Install new rubber mounting grommets in the upper mounting brackets.
   ℹ️New condensers may come pre-filled with oil. Check manufacturer instructions and adjust oil quantity accordingly to avoid overfilling system.
8. 8

   Install new condenser
   Carefully lower the new condenser into position, seating the lower tabs into the radiator support brackets first. Align the upper mounting holes with the radiator support. Ensure the condenser is properly positioned with adequate clearance from the radiator and surrounding components.

9. 9

   Reconnect AC lines
   Install new O-rings on all AC line fittings, lubricating them lightly with fresh PAG oil. Connect the high-pressure and low-pressure lines to the condenser, ensuring proper alignment. Hand-tighten first, then torque to specification using a line wrench. Reinstall any mounting brackets in their original positions.
   ⚠Never reuse old O-rings. Always use new O-rings lubricated with PAG oil to ensure proper seal and prevent leaks.

10. 10

    Reinstall cooling fan assembly
    Position the cooling fan assembly back onto the radiator, aligning the mounting holes. Install and torque the fan shroud bolts to specification. Reconnect the electrical connector to the fan motor, ensuring it clicks into place securely.
11. 11

    Vacuum and recharge AC system
    Connect AC manifold gauges to service ports. Evacuate the system using a vacuum pump for minimum 45 minutes to remove all air and moisture. System should hold vacuum for 15 minutes without loss. Recharge system with refrigerant to specification listed on underhood label (typically 550-650g for this model). Add UV dye if desired for future leak detection.
    ⚠Insufficient vacuum time will leave moisture in system which will freeze at expansion valve and damage compressor. Always vacuum for full 45 minutes minimum.
12. 12

    Leak test and system verification
    Start engine and activate AC system. Use electronic leak detector or soap solution to check all connection points for leaks. Verify compressor engages and system pressures are within specification (typically 25-35 psi low side, 200-250 psi high side at idle with 85°F ambient). Check that condenser fans activate when AC is on.
    ℹ️System pressures vary with ambient temperature. Refer to factory specifications for pressure ranges at different temperatures.

Reassembly

1. Reinstall radiator grille and upper cover panels, ensuring all clips are fully seated
2. Reinstall front bumper cover and engine splash shield
3. Reconnect negative battery terminal
4. Reset any AC-related fault codes using scan tool if warning lights are present

Verification

• Start engine and run AC system on maximum cold setting for 10 minutes
• Verify center vent temperature reaches 40-45°F within 5 minutes of operation
• Visually inspect all AC line connections for signs of oil leakage or refrigerant residue
• Confirm both condenser fans operate when AC is activated
• Verify no AC-related warning lights or fault codes are present
• Check for proper compressor cycling and listen for abnormal noises from AC system
• Perform final UV dye leak check under black light if dye was added during recharge
