Product Details

Four Seasons 55234 is a discharge and suction line assembly for HVAC service on select 2001-2002 Chevrolet Express and GMC Savana platforms, including the Chevrolet G30. The hose assembly is built as an OE-style replacement for R134a air conditioning systems and uses female O-ring connections at both ends for proper sealing at the refrigerant circuit. The manifold and muffler configuration supports the original system layout, while the aluminum and rubber construction balances routing flexibility with line durability. This part cross-references UAC HA11288C for the same application.

Installation Notes and Tips

Verify the vehicle’s R134a system configuration and match the female O-ring end style before installation. Replace the sealing washers and O-rings as part of the repair, and inspect mating surfaces for damage or contamination before connecting the line. Proper evacuation and recharge procedures should be followed after the A/C system is opened.
