Detailed Description

Edelmann 70422 is a power steering pressure line hose assembly for select Chevrolet G10, Chevrolet G20, Chevrolet G30, GMC G1500, GMC G2500, and GMC G3500 vans from 1987-1991. It is specified for vehicles with conventional power steering systems and a reservoir with one return tube, making fitment verification important before installation. This part cross-references Gates 358560 for the same application.

That approach helps the hose fit within the available space around the steering components while maintaining the intended connection layout. Part number 70422 is a direct replacement choice for service work on these GM van platforms.
