(You save)
Keep cold-side and hot-side refrigerant flowing through your A/C system with the Four Seasons A/C Refrigerant Discharge / Suction Hose Assembly 66748. It installs as a direct-fit replacement on the 1996-2002 Chevrolet Express 2500 and 1996-2002 Chevrolet Express 3500, plus the 1996 Chevrolet G30, restoring the plumbing that carries refrigerant to and from the compressor.
Combined discharge and suction line: handles the high-pressure refrigerant leaving the compressor toward the condenser and the low-pressure refrigerant returning to the compressor.
Assembled unit: ships as a hose assembly with its end fittings, so you replace the full line as one part.
Direct-fit application: installs on the listed Chevrolet Express and G30 vans.
Rubber A/C hose can crack, chafe, or leak at the crimped fittings over time. Signs this line may need replacing include refrigerant leaks, oily residue around the connections, or weak A/C cooling. Because low cooling can have other causes, diagnose the system first; if a leaking discharge/suction hose is the cause, this assembly replaces it.
It routes refrigerant between the compressor and the rest of the A/C system, handling both the high-pressure discharge side toward the condenser and the low-pressure suction side back to the compressor.
Which vehicles does it fit?
It's a direct-fit replacement for the 1996-2002 Chevrolet Express 2500, the 1996-2002 Chevrolet Express 3500, and the 1996 Chevrolet G30. Check the Buyer's Guide tab to confirm your vehicle.
What are the signs this hose needs replacing?
Common signs include refrigerant leaks, oily residue around the crimped fittings, or weak A/C cooling. Diagnose the cause first, since low cooling can have other sources.
What numbers does this part interchange with?
It interchanges with 1530886, 781573, 15074398, 15742928, 19209168, 700161, 4814503, 211659, A83344, and HA112052C.
Is it sold as a complete assembly?
Yes. It ships as a complete discharge/suction hose assembly with its fittings, so you replace the full line rather than assembling individual pieces.
