Guide to A/C System O-Ring & Gasket Kits for the 1989-1996 Eagle Summit
Stop your Eagle Summit's A/C from leaking and get the cold air flowing again by replacing its old, brittle seals.
- You must confirm if your Summit uses R12 or R134a refrigerant before buying a kit to ensure the o-rings are made of the correct material.
- Replacing the A/C receiver/drier at the same time you replace the o-rings is mandatory to protect the system from moisture damage.
- This is not a simple DIY job; it requires specialized equipment for refrigerant recovery and recharging, making professional installation necessary.
- Aftermarket kits from brands like Four Seasons and Global Parts are reliable and cost-effective options for this repair.
Is Your Eagle Summit's A/C Blowing Warm?
The most common reason for an A/C system to stop blowing cold is a refrigerant leak. In an older vehicle like the 1989-1996 Eagle Summit, the original rubber o-rings at the A/C line connections can become hard, brittle, and cracked over time. This allows refrigerant and lubricating oil to escape, which is bad for the A/C system and the environment. You might notice an oily, dirty residue at A/C line connections, which is a tell-tale sign of a leak.

The 1989-1996 model years span the transition from R12 to R134a refrigerant. Models made before ~1994 likely used R12, while later models used R134a. If your system has been converted from R12 to R134a, you must use the correct o-rings. Modern kits use green or blue HNBR (Hydrogenated Nitrile Butadiene Rubber) o-rings, which are compatible with R134a and the PAG oil it uses. Using the wrong type of o-ring will cause leaks. Always verify what refrigerant your system uses before buying a kit.
Choosing the Right Aftermarket O-Ring Kit
For a vehicle of this age, finding original equipment (OEM) parts is nearly impossible. Aftermarket kits are the most practical and cost-effective solution. The quality of the o-ring material is the most important factor. Reputable aftermarket brands provide kits with the correct HNBR material for a durable, leak-free seal.
Brand Options for Your Summit:
- Four Seasons: A widely recognized brand in the aftermarket A/C parts industry. They offer comprehensive kits and are generally considered a reliable choice for repairs. Their kits are designed to be application-specific and are compatible with both R12 and R134a refrigerants.
- Global Parts (GPD): GPD is a national distributor of aftermarket A/C components. They provide "Rapid Seal Kits" that include all the necessary o-rings for a specific vehicle's A/C system, designed to meet or exceed original specifications.
For a part like an o-ring kit, both Four Seasons and Global Parts are solid choices. The key is to ensure the kit you purchase is listed as compatible with your specific year of Eagle Summit (or its Mitsubishi Mirage equivalent).
Pro Tip: Replace More Than Just the O-Rings
Anytime the A/C system is opened to the atmosphere, it's mandatory to replace the A/C Receiver/Drier. This component absorbs moisture from the system, and once exposed to air, it becomes saturated and cannot be reused. Failing to replace it can lead to corrosion and the failure of more expensive parts like the compressor.

Frequently Asked Questions
Can I replace the A/C o-rings myself?
This is not recommended for most DIY mechanics. Replacing the o-rings requires specialized equipment to safely and legally recover the old refrigerant, pull a vacuum to remove moisture, and recharge the system with the correct amount of new refrigerant and oil. It's best to have a professional shop handle A/C work.
🎬 Learn more about diagnosing and fixing common A/C problems.Do I need to add oil when replacing o-rings?
Yes. A new o-ring should always be lubricated with the correct type of refrigerant oil (e.g., PAG oil for R134a systems) before installation to ensure a good seal and prevent tearing.
Are there any recalls for the Eagle Summit A/C system?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database show no A/C-related recalls for the 1989-1996 Eagle Summit. Any leaks are typically due to the age and normal wear of the rubber components.
What's the difference between an A/C receiver/drier and an accumulator?
They both remove moisture from the A/C system, but they are used in different system types. Your Eagle Summit uses a receiver/drier, which is located on the high-pressure side of the system. You should not use parts referred to as accumulators.
