Ok so I have the dreaded no or minimal heat in my new to me ram. It had a heater core done recently and has been like this at least since then according to the previous owner.
I read about putting a flush kit T in the heater hose near the core to help release the air. Which side do I put it in drivers or passenger?
Which side is inlet, which is outlet?
Thanks for any help, hoping to solve this asap as its a bit chilly in there now.

Those on passenger side is inlet, hose on drivers side is outlet. You want to put the T in the outlet hose, at its highest point. Unfortunately, that is RIGHT by the heater core. (fun place to work in.....) I just lay across the top of the engine. If the engine is warm, keeps me warm too.
All you should really need to do for the heater core is just start the engine, crack open the T, when you get just coolant flowing, and no more air bubbles, tighten it back up. Once the engine warms, you should have good heat, if you don't, something else is going on.
I bought mine individually from a local parts store. Cost me $2.00 + two clamps. Its a 5/8" T.
I put it on the drivers side beside the brake booster. Was a little distance away from the core outlet but where it is I can lift up the hose and hang it with a piece of wire so its higher than the rest of the system including the heater core while I am bleeding the air out.
Not sure if its the best way but so far it seems to be helping.
Well I still have mediocre heat at best. If its all the way on the hot setting I get warm air at hiway speeds but idling is barely enough to keep windows clear when outside temps are hovering around freezing. My 96 v10 truck would cook me out of the cab like most other vehicles would. So I assume its not normal.
My temp gauge is just above the middle (95*) on a Canadian truck. Which is 203*F so I assume im around 210+.
On the 01, check the temp door motor. Its on the bottom of the heater box, just to the passenger side of of the trans tunnel. There is a plastic coupler in there that likes to break, and the door doesn't move thru its full travel.
