No heat

If your inlet hose is cold too then my guess is that you are real low on coolant.

I flushed it out and added about 2 1/2 gallons when I checked the coolant level I could see some in there

Well theres your problem. Your coolant overflow tank has a fill mark on the side. If it isnt full then fill it. If it goes back down then you have a leak in the coolant system. Once your coolant level gets so low your heater core will get very little coolant if any and without coolant in the heater core you will have no heat. Common leak point is T fitting and couplers at the heater core nipple and hose.

Update.....it's been a while but I performed a total of 3 heater core flushes. The first 2 did nothing then I realized I needed to back flush it. A rather generous amount of pebbles/rocks came out... Heats blowing at 165° now, compared to 65°

Yep next time just grab the heater core hoses if 1 is cold and 1 is hot thats your problem blocked.
