No . Im gonna disconnect the heater hoses tomorrow and see if water flows thru. Replacing the core on these trucks is a colossal pain so I hope it’s not thatDo you get heat in one out of two heater hoses? Maybe the heater core is clogged?
That's the VIS Variable Intake System. Changes the runner length of the plenum.
It runs at the right temp so I don’t think it’s thatthermostate?
Have you checked the thermostat? Mine was stuck in the open position and would never really overheat in the summer but in the winter it didn't heat up at all. I was afraid that on really cold days the coolant would freeze up. I drove my poor granddaughter to school one whole winter like this. When Spring came around I took my car to my mechanic and had him replace the thermostat. That fixed the problem.View attachment 394905I have a 1997 explorer 4.0 sohc that has no heat . I’ve done the bleed procedure to no effect as the heater hoses have not heated up . I’ve replaced the blend door and actuator previously so I know it’s not that and also sent the automatic climate control has been rebuilt . Does anyone know how to test the heater control valve or to bypass it . I’m ok if the heat and AC only works if full on . Also wHat does the device in the attached picture does . It’s righ behind the iac valveon the intake manifold

By virtue of it being stuck in the open position and never closing, the coolant will never heat up because it is contiually flowing through the radiator. On the heat gauge, never moved in cold weather. Anyway, I'm interested in what the final esult will be when you find the problem. Please be sure to post it. Good luck. BTW I replaced the heater coil, the sensors on the doors, had my radiator flushed, before I went with my own judgement and fixed the problem. It can get out of hand
I once unclogged a heater core with air pressure without removing it.

It was the heater core. Back flushed it and a lot of crap came out . Heat works great now. Thanks everyone for the advice !
