|---|---|---|
| Refrigerant Type | R-1234yf | R-1234yf |
| Refrigerant Capacity | 1.94 lbs (880 g) | 2.31 lbs (1050 g) |
| Refrigerant Capacity (Ounces) | 31.0 oz | 37.0 oz |
| Compressor Oil Type | PAG Oil PSD-1 | PAG Oil PSD-1 |
| Compressor Oil Capacity | 140 ml (4.73 oz) | 190 ml (6.42 oz) |
| System Application | Front A/C Only | Front and Rear Climate Control |
The exact refrigerant capacity depends on whether the vehicle is equipped with a front-only air conditioning system or a dual-zone front and rear climate control system.

Understanding the Pacifica’s A/C System
The air conditioning system in the Chrysler Pacifica consists of several major components that work together to cool the cabin:
- Compressor
- Condenser
- Evaporator
- Expansion valve
- Refrigerant lines
- Cabin air filter
The refrigerant circulates throughout the system, absorbing heat from inside the vehicle and releasing it outside. Maintaining the correct refrigerant charge is critical for efficient heat transfer and cooling performance.

Single vs. Dual A/C Systems
Single A/C System
Some Pacifica models are equipped with a front-only climate control system. These vehicles use:
- Refrigerant Type: R-1234yf
- Refrigerant Capacity: 1.94 pounds (880 grams)
This setup cools the front passenger compartment and typically requires less refrigerant because of its smaller system volume.
Dual A/C System
Many Pacifica trims include rear passenger climate controls. These systems feature additional components such as rear evaporators and refrigerant lines.
Specifications include:
- Refrigerant Type: R-1234yf
- Refrigerant Capacity: 2.31 pounds (1050 grams)
The larger system volume requires additional refrigerant to operate efficiently.

Why Refrigerant Capacity Matters
Using the correct refrigerant charge is important for several reasons.
Undercharged System
If the system contains too little refrigerant, you may experience:
- Reduced cooling performance
- Warm air from vents
- Poor cooling at idle
- Compressor cycling
- Increased strain on system components
Overcharged System
Adding too much refrigerant can also cause problems, including:
- High operating pressures
- Reduced cooling efficiency
- Compressor stress
- Potential damage to seals and hoses
- Increased repair costs
For best results, the system should be evacuated and recharged according to factory specifications.

Compressor Oil Specifications
In addition to refrigerant, the A/C compressor requires specialized lubricant.
The 2017 Chrysler Pacifica uses PAG PSD-1 compressor oil.
System Type Oil Capacity
Single A/C. 140 ml (4.73 oz)
Dual A/C 190 ml (6.42 oz)
Using the correct oil type is essential because it lubricates moving compressor components and helps ensure long service life.
Common Air Conditioning Problems
As the vehicle ages, several A/C-related issues may develop.
Refrigerant Leaks
Refrigerant leaks are among the most common air conditioning problems. Leaks may occur from:
- O-rings
- Hoses
- Condenser
- Compressor seals
- Evaporator core
When refrigerant levels drop, cooling performance declines, and the system may eventually stop producing cold air.

Compressor Failure
The compressor is the heart of the air conditioning system. Signs of compressor problems include:
- Loud noises
- Clicking sounds
- Warm air from vents
- Intermittent cooling
- Compressor clutch failure
Prompt diagnosis can prevent additional damage to other A/C components.
Condenser Damage
The condenser is mounted near the front of the vehicle and is vulnerable to road debris. Damage can lead to refrigerant leaks and poor cooling performance.
Rear A/C Issues
Vehicles equipped with rear climate control may experience:
- Weak airflow from rear vents
- Warm rear air
- Rear blend door problems
- Expansion valve issues
In many cases, low refrigerant levels affect rear cooling before front cooling.
Signs Your Pacifica Needs A/C Service
Several symptoms may indicate the need for air conditioning maintenance or repair:
- Air is not blowing cold
- Reduced cooling performance
- Unusual noises from the A/C system
- Compressor cycling frequently
- Foggy windows due to excess humidity
- Uneven cooling between front and rear vents
If these symptoms occur, the system should be inspected by a qualified technician.
Can You Use R-134a Refrigerant?
No. The 2017 Chrysler Pacifica was designed specifically for R-1234yf refrigerant.
Using R-134a in an R-1234yf system can result in:
- Reduced cooling efficiency
- Improper pressure readings
- Compressor damage
- System contamination
- Expensive repairs
Always use the refrigerant specified by the manufacturer.
Air Conditioning Maintenance Tips
Proper maintenance can help maximize system performance and lifespan.
Replace the Cabin Air Filter
A dirty cabin air filter restricts airflow and can reduce cooling efficiency. Replace the filter according to the maintenance schedule.
Run the A/C Regularly
Even during colder months, operating the A/C periodically helps lubricate seals and maintain system health.
Keep the Condenser Clean
Remove leaves, dirt, and debris from the condenser to ensure proper airflow and cooling performance.
Repair Leaks Promptly
If refrigerant loss is detected, identify and repair the leak before recharging the system.
Use the Correct Refrigerant
Always use R-1234yf refrigerant and the specified PAG PSD-1 compressor oil.
Frequently Asked Questions
What Refrigerant Does a 2017 Chrysler Pacifica Use?
The 2017 Chrysler Pacifica uses R-1234yf refrigerant.
How Much Refrigerant Does a 2017 Chrysler Pacifica Hold?
Models with a single A/C system hold approximately 1.94 pounds (880 grams), while dual A/C systems hold approximately 2.31 pounds (1050 grams).
What Oil Does the A/C Compressor Use?
The recommended compressor oil is PAG PSD-1.
Can Low Refrigerant Cause Poor Cooling?
Yes. Low refrigerant is one of the most common causes of reduced cooling performance and warm air from the vents.
Does Refrigerant Wear Out Over Time?
No. Refrigerant is not consumed during normal operation. If levels are low, a leak is usually present somewhere in the system.
Final words
Knowing the correct 2017 Chrysler Pacifica refrigerant capacity is essential for maintaining proper air conditioning performance. Models equipped with a single A/C system require 1.94 pounds (880 grams) of R-1234yf refrigerant, while dual A/C systems require 2.31 pounds (1050 grams).
