So before I get started, here's the status:
-new thermostat
-new water pump
-fresh coolant
-system flushed
-no clogs
-heater core flushed, no leaks
Explorer runs like a DREAM! Temp gauge gets to half point, and runs at a perfect temp.
After the new coolant, burped the system, and with the rad cap off, you can see consistent flow. Water pump is going strong, and coolant temp is good.
Now, hose coming from thermostat housing that goes to heater core had coolant in it once I pulled the hose. Once the temp goes up, water pump kicks in, hose connected to thermostat housing going to heater core is hot, but is cool once you get towards the heater core. Which means the coolant isnt flowing to the heater core.
Why is this?
