Heater Core hoses diagram for Dual Heater system 86' Gmc Van

\015 I need a reference of some type to return the hoses for the heaters in the correct places after installing a new heater core. It has a heater in the dash and one in the rear of the cabin. Please help with a diagram or some type of explicit verbal instruction. I'm lost. Thanks,\015\012\015\012Tim\015 Posted / edited by AnonymousUser on : 11-11-2019
