- R-134a refrigerant
- A/C recharge hose kit
- A/C manifold gauge set
- Safety glasses
- Gloves
Once you have gathered the necessary tools and materials, follow these steps:
1. Park the Elantra in a well-ventilated area and turn off the engine.
2. Locate the low-pressure port on the A/C system. It is usually located on the passenger side of the engine compartment and has a blue cap.
3. Connect the A/C recharge hose to the low-pressure port.
4. Connect the manifold gauge set to the A/C recharge hose.
5. Open the valve on the refrigerant can and slowly begin adding refrigerant to the system.
6. Watch the pressure gauges on the manifold gauge set. The low-pressure gauge should read between 25 and 45 psi, and the high-pressure gauge should read between 150 and 250 psi.
7. Continue adding refrigerant until the pressures on the gauges reach the desired levels.
8. Once the pressures have been reached, close the valve on the refrigerant can and disconnect the A/C recharge hose and manifold gauge set.
9. Start the engine and turn on the A/C system.
10. Check the temperature of the air coming out of the vents. It should be cool and refreshing.
If the air coming out of the vents is not cold, you may need to add more refrigerant to the system.
