Four Seasons A/C Refrigerant Discharge Hose P/N:66689
Four Seasons A/C Refrigerant Discharge Hose P/N:66689
$23.99

Keep your air conditioning routing high-pressure refrigerant where it belongs with the Four Seasons A/C Refrigerant Discharge Hose 66689, a direct-fit replacement for the 1997-2002 Mitsubishi Montero Sport. The discharge (high-side) hose carries hot, high-pressure refrigerant from the compressor's discharge port to the condenser, so a cracked, chafed, or leaking original can leave the system low on charge and cooling poorly.

  • Job it does: routes high-pressure refrigerant from the compressor to the condenser on the discharge side of the A/C circuit.
  • Direct-fit application: replaces the original discharge hose on the listed Montero Sport years.
  • Signs it may need replacing: visible oil residue at the fittings, refrigerant leaks, weak cooling, or a hose that is chafed, cracked, or swollen.

If a failed discharge hose is the source of your A/C leak, this hose replaces it; have the system diagnosed, evacuated, and recharged by the service procedure after installation.

Frequently Asked Questions

What does this hose do?

It carries hot, high-pressure refrigerant from the A/C compressor's discharge port to the condenser on the high side of the system.

Which vehicles does it fit?

How do I know my discharge hose is bad?

Common signs include oily residue at the fittings, refrigerant leaks, weak cooling, or a hose that is chafed, cracked, or swollen. Have the system diagnosed to confirm the cause.

Will replacing this hose fix my A/C?

If a leaking or damaged discharge hose is the cause, this replaces it. Other components can also cause weak cooling, so diagnose the system first.
