Heater hose placement schematic
Hose from the water pump goes to heater(PS).
Hose from thermostat goes to control valve(closest to firewall).
Hose from control valve(closest to front), goes
to heater(DS) | | | | | Joined: Jun 2021 Posts: 69 'Bolter | | 'Bolter Joined: Jun 2021 Posts: 69 | hopefully i didnt cause any damage to the valve i had those connections reversed | | |
