Detailed Description

This Four Seasons 56686 hose assembly is built for the A/C refrigerant path on 1989-1991 Ford E-150 Econoline, E-150 Econoline Club Wagon, and E-250 Econoline models. The assembly uses aluminum and rubber construction, a female springlock discharge end, a female springlock suction end, and a manifold with muffler to match the original routing and connection style used on these vehicles.
