The A/C hoses transfer refrigerant throughout the system so you can cool down the interior of your vehicle. The A/C hoses are subject to constant abuse, being exposed to engine bay temperature and the constant pressure of refrigerant when the A/C compressor is running. Replace A/C hoses as soon as any damage is identified to keep your A/C system operating properly. This A/C hose connects the rear hose section from the evaporator, where the restrictor valve is located, to the condenser.

When are you are replacing your A/C hose, examine the rest of the A/C system to be sure that all the damaged hoses or components are being replaced.
