how hard is it to flush heater core

Pretty Simple. I dont remember which hoses are which, but you need to find the two that go into the heater core. The are one on top of the other, on the drivers side of the firewall. Then find which one of the two is the outlet. This is the hose that you will hook your flush into, to go "back" through the core, hence the term back flush. You want to go reverse of the normal flow of coolant because you get a lot more crap out this way. Hook a hose up to this. I used a barbed plastic connector that we got for like garden hoses. Take the Inlet hose off, and point it in a bucket or on the ground if you dont care, so all the water you flush through doesnt get into the system.
If you want to do it well, I would actually flush through both ways. Reverse first, then normal flow direction. This is what I did. Afterwards, my heat worked great.
This whole process took my dad and I maybe twenty minutes. You actually only have to have water running through for about 30 seconds or less. The rest of it is prep time. If I made anything confusing let me know, I can try and make more sense lol
