Dorman - OE Solutions A/C Hose Assembly P/N:926-866
Swap out corroded rear auxiliary A/C lines for flexible hose that is easier to route under the vehicle. The Dorman OE Solutions A/C Hose 926-999 is a direct-fit replacement for the 2002-2006 Chevrolet Trailblazer EXT and 2002-2006 GMC Envoy XL. The original rear auxiliary lines are aluminum, and exposure to the elements under the vehicle can corrode them until the air conditioning system fails. This A/C hose assembly is part of Dorman's OE FIX line. It uses flexible reinforced rubber in place of the original aluminum to make installation simpler.
This assembly carries refrigerant, so the A/C system must be properly recovered, evacuated and recharged during installation. Consult the vehicle service information for the correct procedure and refrigerant specifications. Engine details for each vehicle are in the Buyer's Guide tab.
