Remove and replace the AC condenser on a 2005 Dodge Viper, including refrigerant recovery, front fascia removal, and system recharge.

Warnings

⚠️AC system contains refrigerant under high pressure. Recovery must be performed by certified technician with proper equipment. Venting refrigerant to atmosphere is illegal.

⚠The Viper front fascia is lightweight composite material. Use care when removing and storing to avoid cracking or flexing damage.

⚠Replace all AC line O-rings during reassembly. Reusing old O-rings will result in refrigerant leaks.

Preparation

Park vehicle on level surface and engage parking brake.
Disconnect negative battery cable.
Recover AC refrigerant using certified AC recovery equipment. Note the amount recovered for recharge reference.
Raise front of vehicle and support on jack stands at manufacturer lift points.
Allow engine to cool completely if recently operated.

Procedure

1
Remove front wheel well liner fasteners
Remove the front wheel well liner push clips and fasteners on both sides to access the outer edges of the front fascia. The liner does not need to be completely removed, but must be loosened to access fascia mounting points.
2
Remove front fascia lower fasteners
From underneath the vehicle, locate and remove the lower front fascia mounting bolts. There are typically 6-8 fasteners along the lower edge of the fascia. Remove the undertray panels as needed to access these fasteners.
3
Remove front fascia upper and side fasteners
Open the hood. Remove the upper fascia mounting bolts along the top edge near the hood latch area. Remove the side mounting fasteners accessible from the wheel well openings. Support the fascia with a helper or padded surface before removing the final fasteners.
⚠The fascia is large and unwieldy. Use a second person or padded work surface to prevent damage when separating from vehicle.
4
Remove front fascia assembly
With all fasteners removed, carefully pull the front fascia forward and away from the vehicle. Disconnect any fog light or auxiliary light connectors if equipped. Store the fascia on a padded surface away from the work area.
5
Remove radiator support cover
Remove the plastic radiator support cover panel if equipped. This cover sits above the radiator and condenser assembly and is secured with push clips or small bolts along the top edge.
6
Disconnect AC lines from condenser
Locate the AC line connections at the condenser. Using a line wrench to prevent rounding, disconnect the high-side and low-side AC lines from the condenser. Immediately cap the open lines and condenser ports to prevent contamination. Remove and discard the old O-rings from the line fittings.
⚠Even after recovery, some residual refrigerant pressure may remain. Wear safety glasses and gloves.
7
Remove condenser mounting hardware
Remove the condenser mounting bolts securing the condenser to the radiator support brackets. The condenser is typically secured with 4 bolts at the upper mounting tabs. Note the position of any spacers or insulators between the condenser and radiator.
Torque spec
Condenser Mounting Bolts12 Nm (9 lb-ft)
8
Remove condenser from vehicle
Carefully lift the condenser up and out of the engine compartment. The condenser sits in front of the radiator and may require tilting to clear the radiator support. Drain any residual oil from the old condenser into a measuring container to determine how much fresh PAG oil to add to the new condenser.
9
Prepare new condenser
Add the appropriate amount of fresh PAG oil to the new condenser (typically 50ml, adjusted for any oil drained from the old condenser). Remove protective caps from the new condenser ports just before installation to minimize contamination exposure.
10
Install new condenser
Position the new condenser into the radiator support area, ensuring proper alignment with mounting brackets. Install any spacers or insulators in their original positions between the condenser and radiator. Install the condenser mounting bolts finger-tight, then torque to specification.
Torque spec
Condenser Mounting Bolts12 Nm (9 lb-ft)
11
Connect AC lines to condenser
Install new lubricated O-rings onto the AC line fittings (coat lightly with PAG oil). Connect the high-side and low-side AC lines to the new condenser. Torque the line fittings to specification using a line wrench.
ℹ️Cross-threading aluminum AC fittings will destroy the condenser ports. Thread fittings by hand first to ensure proper engagement before using wrench.
Torque spec
AC Line Fittings20 Nm (15 lb-ft)
12
Reinstall radiator support cover
Reinstall the radiator support cover panel if equipped, securing with all original fasteners and push clips.
13
Reinstall front fascia
With a helper, position the front fascia onto the vehicle. Reconnect any fog light or auxiliary light connectors. Install the upper, side, and lower fascia mounting fasteners in reverse order of removal. Verify proper alignment and gaps before fully tightening all fasteners.
14
Reinstall wheel well liner fasteners
Secure the wheel well liners with all original push clips and fasteners on both sides.
15
Evacuate and recharge AC system
Connect AC service equipment. Evacuate the system to 29+ inches of vacuum for a minimum of 30 minutes to remove air and moisture. Monitor for vacuum hold to verify system integrity. Recharge with the amount of R-134a specified on the underhood label for this vehicle. Add UV dye if desired for future leak detection.

Reassembly

Reconnect negative battery cable.
Lower vehicle from jack stands.
Start engine and verify AC system operation through all temperature and fan settings.
Inspect all AC line connections for signs of oil residue indicating leaks.

Verification

Run AC system for 10 minutes and verify cold air output at all vents.
Check that both high-side and low-side pressures are within manufacturer specifications using AC manifold gauges.
Inspect all AC line connections for leaks using electronic leak detector or soap solution.
Verify front fascia alignment and that all mounting points are secure.
Confirm fog lights and any auxiliary lights function properly if equipped.
