I have a 2004 Hyundai Santa Fe 3.5L AWD.
I want to "back flush" the heater core, but I can't find the hoses that go to the heater core. I can only see the main radiator hoses that go in and out of the radiator.
If I take out the thermostat, is there a way for me to back flush the heater core by just using the large radiator hoses?
If so, I assume that the return hose at the top of the radiator would be the one that I would use to back flush the heater core -- since I think that would be a way to reverse the flow through the system.
Am I right about that?
Thanks.
