Replacing the A/C Compressor on a 1981-1986 Dodge Colt
Keep your classic Colt cool with the right new aftermarket A/C compressor.
- For a 1981-1986 Dodge Colt, a new aftermarket compressor is the only practical replacement option.
- When the compressor fails, you must flush the system and replace the receiver/drier and expansion valve to prevent damage to the new part.
- The original R-12 refrigerant system will need to be converted to modern R-134a during the repair.
- This repair requires special tools for handling refrigerant and is best left to a professional shop.
Is Your Dodge Colt's A/C Blowing Warm Air?
If the air conditioning in your 1981-1986 Dodge Colt isn't working, a failed A/C compressor is a likely culprit. This component works hard under the hood and is subject to wear and tear over time. Understanding the signs of failure can help you decide if it's time for a replacement.
Common Symptoms of a Failing A/C Compressor
- Warm Air from Vents: The most obvious sign is when the A/C system blows air that is not cold, even at the coldest setting. This happens when the compressor can no longer effectively pressurize and circulate the refrigerant.
- Strange Noises: A grinding, squealing, or rattling sound when you turn the A/C on points to internal mechanical failure. The bearings or other internal parts may be worn out.
- A/C Clutch Not Engaging: The compressor has a clutch on its pulley that engages to turn the compressor's internal parts. If you turn on the A/C and don't hear a "click" or see the center part of the pulley start spinning, the clutch may have failed.
- Leaking Fluid: The compressor contains seals that can fail over time, leading to refrigerant and oil leaks. You might see an oily residue on the body of the compressor.
System Contamination is a Major Concern
When a compressor fails internally, it can send metal shavings and debris throughout the entire A/C system. Simply replacing the compressor is not enough. If you don't flush the system and replace the receiver/drier and expansion valve, the debris will destroy your new compressor, leading to another costly repair.
Choosing the Right Aftermarket Compressor
For a vehicle from the early to mid-1980s like the Dodge Colt, finding a brand-new Original Equipment Manufacturer (OEM) compressor is nearly impossible. The only practical option is a new aftermarket part. Fortunately, aftermarket brands offer quality replacements designed to fit and function like the original.
When shopping, you will encounter brands like Four Seasons and Global Parts Distributors (GPD). Both are well-established in the aftermarket industry.
- Four Seasons: A very large and long-standing manufacturer and remanufacturer of A/C parts. They have a reputation for producing reliable components and often incorporate design improvements to fix common factory flaws. Many users in forums report good experiences with their new compressors.
- Global Parts Distributors (GPD): Another major supplier of aftermarket A/C components. GPD parts are known for good fitment and are available in a wide range of options, from single parts to complete kits.
Pro Tip: Always buy a kit. A/C compressor warranties almost always require you to replace the receiver/drier (or accumulator) and expansion device at the same time. Buying a kit that includes these parts ensures you have everything needed for a successful and warrantable repair.
Estimated Cost for a New A/C Compressor
The cost to replace the A/C compressor on your Dodge Colt will vary based on labor rates in your area. Because this is an older vehicle, the A/C system is relatively simple compared to modern cars, which can help keep labor costs down.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket A/C Compressor | $242 - $291 |
| Shop Labor (including system evacuation and recharge) | $300 - $500 |
| Total Estimated Cost | $542 - $791 |
Note: Prices are estimates and can vary. Labor costs are based on a general estimate for this type of vehicle.
Frequently Asked Questions
Do I need to add oil to the new compressor?
Most new aftermarket compressors come pre-filled with the correct amount of oil. Always check the manufacturer's instructions included with the part. It is critical to have the correct oil charge for the entire system, which may require draining and measuring the oil from the old compressor to ensure the new system has the right balance.
Can I replace the A/C compressor myself?
This is a job for an experienced DIY mechanic with the right tools. Replacing the compressor requires specialized equipment to safely recover the old refrigerant and then evacuate and recharge the system. Improper handling of refrigerant is harmful to the environment and can cause injury. For most owners, professional installation is recommended.
My Colt uses R-12 refrigerant. What should I do?
Yes, your 1981-1986 Dodge Colt originally used R-12 refrigerant, which is no longer available for general use. You will need to have the system converted to use modern R-134a refrigerant. This is a standard procedure that any competent A/C shop can perform during the compressor replacement. It involves using different service fittings and ensuring the correct type of oil (PAG oil) is used for the R-134a system.
Were there any recalls for the A/C compressor on the 1981-1986 Dodge Colt?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any A/C-specific recalls or widespread issues for the 1981-1986 Dodge Colt. Any problems you experience are likely due to the age and normal wear of the components.
