Mitsubishi Outlander A/C Compressor Guide: 2013-2020 Models
Is your Outlander's A/C blowing warm? Here's what you need to know about replacing your A/C compressor.
- A failing A/C compressor will cause warm air, strange noises, or may not engage at all.
- Always replace the receiver/drier and expansion valve when installing a new compressor to prevent damage.
- Choosing a new aftermarket compressor from a reputable brand like Four Seasons offers significant savings over OEM without sacrificing reliability.
- The A/C system must be professionally evacuated and recharged by a certified mechanic, even if you install the part yourself.
Is Your Outlander's A/C Ready for the Heat?
When the air conditioning in your 2013-2020 Mitsubishi Outlander starts blowing warm, a failing A/C compressor is a common suspect. This component works hard to keep you cool, but like any mechanical part, it can wear out. Understanding the signs of failure and your replacement options can save you from a hot, uncomfortable drive.
Symptoms of a Failing A/C Compressor
A bad compressor can show several signs. Being aware of them can help you diagnose the problem before the system stops working completely.
- Warm Air: The most obvious symptom is air from the vents that isn't cold, even with the A/C on full blast. 🎬 Watch: A diagnostic walkthrough for an Outlander blowing warm air. This can happen if the compressor isn't engaging to pressurize the refrigerant.
- Strange Noises: A squealing or grinding noise when you turn the A/C on often points to a problem with the compressor or its clutch. You might also hear rattling sounds if the compressor's internal parts are failing. 🎬 Check this guide to find your A/C fuses and relays.
- Compressor Clutch Not Engaging: Look at the A/C compressor with the engine running and the A/C turned on. The center part of the pulley (the clutch) should be spinning with the belt. If it's stationary or cycles on and off rapidly, there's a problem.
- Visible Leaks: The compressor can be a source of refrigerant leaks. You might see an oily residue on the compressor body. 🎬 See how to identify and replace a leaking compressor. Sometimes a large leak can even produce visible smoke or steam from under the hood.
Don't Just Add Refrigerant
If your system is low on refrigerant, it has a leak. Simply adding more is a temporary fix at best and wastes money. The system is sealed, and the only reason for low refrigerant is a leak that needs to be repaired.
Choosing the Right Aftermarket Compressor
When replacing the A/C compressor on your Outlander, you have a choice between an Original Equipment Manufacturer (OEM) part from Mitsubishi and an aftermarket part. OEM parts are expensive, often costing over $1,000. Aftermarket parts offer significant savings and can be a reliable alternative.
- New vs. Remanufactured: Always choose a new aftermarket compressor over a remanufactured (rebuilt) one. While rebuilt parts are cheaper, they have a higher failure rate. Forum users have reported receiving multiple bad rebuilt compressors in a row. A new part provides better peace of mind.
- Brand Reputation: Brands like Four Seasons are well-regarded in the aftermarket for A/C components and are often recommended by mechanics for their balance of quality and value. Other brands like Global Parts (GPD) and UAC are also available, though some users have reported issues like early clutch failure with GPD or leaks with UAC. Sticking with a trusted brand like Four Seasons is a safer bet.
Replace More Than Just the Compressor
When a compressor fails, it can send small metal particles throughout the A/C system. To prevent your new compressor from being damaged, it is critical to also replace the A/C receiver/drier (or accumulator) and the expansion valve. The entire system should also be professionally flushed to remove any contaminants.
Cost of Replacing a 2013-2020 Outlander A/C Compressor
The total cost depends on whether you do the work yourself and the parts you choose. Note that the refrigerant must be legally recovered and recharged by a certified shop, even for a DIY installation.
| Part/Service | Estimated Cost |
|---|---|
| New OEM A/C Compressor | $1,063 - $1,675 |
| New Aftermarket A/C Compressor | $275 - $530 |
| Shop Labor (Installation) | $258 - $378 |
| Total Professional Job (Aftermarket Part) | $533 - $908 + cost of drier/valve/flush |
| Total Professional Job (OEM Part) | $1,321 - $2,054 |
Frequently Asked Questions
Are there any recalls on the 2013-2020 Outlander A/C compressor?
No, there are no specific recalls for the A/C compressor on the 2013-2020 Mitsubishi Outlander. There are some Technical Service Bulletins (TSBs) for newer models (2022+) related to A/C control software, but not for compressor failure in this year range.
Can I replace the Outlander A/C compressor myself?
This is a moderately difficult job. While the mechanical steps of unbolting the old compressor and installing the new one are feasible for an experienced DIYer, the A/C system's refrigerant must be handled by a professional shop with the proper equipment. You must have the system evacuated before you start work and professionally vacuumed and recharged after you are done.
My A/C works when I'm driving but not when I'm stopped. Is it the compressor?
This specific issue is often caused by faulty radiator cooling fans, not the compressor itself. When the car is stopped, the fans are supposed to pull air across the condenser to cool the refrigerant. If they aren't working, the A/C will only get cold when the car is moving and air is naturally forced through the grille.
What is an A/C compressor clutch and can I just replace that?
The clutch is the part of the compressor that engages and disengages it from the engine's belt. While it is sometimes possible to replace just the clutch, it is generally not recommended. The labor involved is often similar to replacing the whole unit, and if the compressor is old, another part of it may fail soon after. Most mechanics advise replacing the entire compressor assembly for reliability.
