My mom's A/C is leaking at the part of the discharge line that connects to the hose piece and the other hose coming from the condenser is cracked. So I wanted to go ahead and replace it. I wanted to know if I could get a piece of hose to replace it and if there was a connector that can be replaced or something. I can get pictures if needed.

Good afternoon,

No, there is no repairing a leak with a hose and clamps due to the high pressures.

Please post a picture for me.

I attached a picture of the lines and the procedure for replacement.

Removal and Installation

NOTE:
The O-ring seals used on this vehicle are not interchangeable with all similarly sized O-ring seals used on other Ford products. Use only the O-ring seals specified for this vehicle in the Ford master parts catalog.
Installation of a new receiver/drier desiccant bag is not required when repairing the A/C system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the receiver/drier desiccant bag.
The compressor-to-condenser discharge line consists of 2 separately serviceable lines. If only one line is to be removed, only carry out the steps qualified for that line.

Both compressor-to-condenser discharge lines
1. Recover the refrigerant.
2. With the vehicle in NEUTRAL, position it on a hoist.
3. Remove the compressor-to-condenser discharge line fitting nut and disconnect the fitting.
Discard the O-ring seal.
To install, tighten to 8 Nm (71 lb-in).

4. Remove the front bumper cover.
5. Drain the engine coolant.
6. Release the upper radiator hose clamp and disconnect the upper radiator hose from the radiator.
7. Remove the engine cooling fan.
8. Remove the compressor-to-condenser discharge line bracket bolt.
To install, tighten to 7 Nm (62 lb-in).

9. Disconnect the A/C pressure transducer electrical connector.
10. Detach the 2 radiator brackets from the core support and position the radiator rearward.
11. Remove the condenser inlet fitting bolt and disconnect the fitting.
Discard the O-ring seal.
To install, tighten to 6 Nm (53 lb-in).

12. Detach the compressor-to-condenser discharge line-to-radiator clip.
13. Remove the condenser side compressor-to-condenser discharge line.

Thank you,

You will need to replace the discharge line.

I found the line at rock auto for you and posted it below.

What about the line that has some cracks on it? It's not leaking yet from there but the place where the metal line and hose meet on the other picture is definitely leaking from there.

Yes. Replace that line as well. Since you have the system open I would replace the accumulator line as well.

I would, yes. If they are cracked, now is the time to do it.

It is better than one line at a time in the heat.
