Does anybody know if it makes a difference which of the two water lines go to which heater core connection.
I am having a tough time diagnosing my cold heater air root cause and if it makes a difference I will swap the hoses/connection to core to see if it makes a difference.
So far I have flushed the core once with a water hose.
I put a new thermostat in last week.
The trap door that is operated by the cable labeled heat --->max seems to be operating correctly and makes movement noises. I can't see it, so not real sure whats actually taking place.
I have felt the hoses after running it 30 mins or so at highway speeds and there may be a slight difference in temp from one core hose to the other but not significant.
Funny thing, even the hose from the block to the radiator is not hot to the touch, just a little above warm.
Fan works fairly well, don't know if I want to mess up my firewall paint to install a bronco fan motor.
I live in the sunny south and my jeep is only driven for pleasure so I can leave it be if it is too cold.
That said, I would like to get it working anyway.
I really think I need to flush the core some more and bought some Preston flush this morning.
So back to the original question, does it make a difference which hose goes to which heater core connection?
