Manche757 Posted Friday at 05:00 PM Share Posted Friday at 05:00 PM 89 MJ, 4.0, 5 speed Replacing cooling system. Closed system. Does anyone have a diagram of what hose layouts should be? Heater control valve is still in place. Especially need the layout for the hose to the reservoir tank. Link to comment Share on other sites More sharing options...
hgeranium Posted 6 hours ago Share Posted 6 hours ago I don’t have a diagram but I can give you a picture of my heater hose set up. 4.0 closed system with HCV. Let me know if you need a different angle or a close up Link to comment Share on other sites More sharing options...

Do you know if that was the original configuration? Yes this is the original configuration. And sorry, I accidentally omitted that picture. It goes to the thermostat. Top hose from the reservoir goes down and splits, one through the heater control valve to the heater core and the other straight to the thermostat Hose on the bottom of the reservoir splits, one end to the heater core, and the other end going to the thermostat The hose on the top of the thermostat connects to the top of the reservoir. The small hose on the bottom (beneath the upper rad hose) connects to the bottom of the reservoir. Link to comment Share on other sites More sharing options...
