Here's a general guide on the steps involved in replacing an A/C evaporator in a 1995 Saturn SL2. These steps are meant as general guidelines and may not be applicable to all vehicles, so always consult your car's repair manual for specific instructions:
1. Refrigerant Recovery:
- If your car still has refrigerant in the system, it needs to be recovered using an A/C recovery machine. This is a regulated procedure, and you may need to hire a certified technician to do it.
2. Accessing the Evaporator:
- Locate the evaporator core inside the car's dashboard. In most vehicles, including the 1995 Saturn SL2, it's located behind the glove compartment.
- Remove the glove compartment, dashboard panels, and other components blocking access to the evaporator housing.
3. Evaporator Removal:
- Disconnect the A/C lines and any electrical connectors connected to the evaporator core.
- Remove any mounting bolts or screws holding the evaporator in place.
- Take out the old evaporator core carefully, being mindful of any remaining refrigerant in the system.
4. Expansion Valve Replacement (if required):
- While you have access, check the expansion valve (if applicable for your vehicle). It might be the source of your evaporator problems. Replace it if necessary.
5. Evaporator Installation:
- Position the new evaporator core in its designated location.
- Reconnect all the A/C lines and electrical connectors.
- Secure the evaporator with the mounting bolts or screws.
6. Recharging the A/C System:
- After reinstalling the evaporator, the A/C system needs to be vacuumed and recharged with the appropriate amount of refrigerant. This step should be performed by a qualified technician with proper equipment.
7. Testing and Troubleshooting:
- Once recharged, test the A/C system to ensure proper cooling and functionality. If you encounter any problems, you might need to troubleshoot further.
8. Reinstall Dashboard Components:
- Lastly, reinstall all the dashboard panels, glove compartment, and other components you removed during the process.
Remember, this is a complex procedure that requires knowledge of HVAC systems and refrigerant handling. If you're not comfortable with these tasks, it's best to entrust this work to a trained professional.
