I need help figuring out why my heat won't work!!

Ok last winter my heat worked but wasn't great. It would cut in and out. In early summer I decided to do the egr delete and oil cooler. My coolant was the nastiest I have ever witnessed to come out of a vehicle. I was an intense 2 or 3 day flush followed by the new cooler and egr delete. As it got colder I noticed my heat to not work. It was just under 30 degrees when I left work tonight. Windows iced up and no heat. That pretty did it for me. It needs to be fixed. Could the heater core be clogged? The reason I think it's clogged is because the coolant was like sludge. Is there anything else that could cause no heat?

Did you replace the thermostat? Try that as well as disconnecting the 2 lines on the heater core and use a shopvac to try to suck them out and then use water to try to flush it out while your using the shopvac on the other hose. Then switch it up and repeat. Put it back together and see if that worked.

I actually replaced my thermostat a week ago with no luck. I might have to try that. If I can flush/vacuum It out it will save me from having to replace it. Worth a Try. I should lose much coolant should I? Just remove the hose and tie them up?

You will lose some coolant but it shouldn't be a whole lot. Just drain the degas bottle first then disconnect the lines and go to work.

Turn your heater on, make sure the valve is operating correctly, feel the inlet hose to see if it is hot, then check the outlet hose to see if it is warm. If you dont put the fan on high, you should be able to tell that coolant is circulating. The outlet should not be cool.

Update. Got home after work. Turned the heat on as I ran down the driveway. Got out after a couple minutes and both hoses felt a little warm. It was a warm as in they are next to the motor not coolant flowing through warm. Is there a valve of some sort that can go bad?

Make sure this valve is moving when you switch to hot or cold. The grey hose should be plugged in.
