Anyone have a diagram for heater hose routing for a Chevy G20 (1990, 5.7.l ) WITHOUT a rear/aux heater?
been looking online and found nothing useful.
Just removed the rear heater and all the hoses because of leaks. Almost done replacing all the hoses and old couplers.
Installed a new 4way heater valve (right at the in/out of the cab heater) and it leaked so it's going back; i would prefer not to wait for another and be done with this.
Seems to me hose to heater routing could be way more simplified. I have a feeling that 4way Im using is only because there was a rear heater.
