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.

 

Ok thank you. Do you think doing it withough draining the system will work?

 

Certainly. You may lose a little bit when you cut the hose, just don't let the free end flop down to low, or it will suck out a bunch.

 

Well put the T in, been burping it for a couple hours. It's gradually getting better but still not great. Are these cores really this much of a pain to bleed?

 

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.

 

What size Flush T did you get? I'm going to do this as well.

 

I don't think you can get them individually, they come in a kit. It will have a couple different sizes.... use the one that fits.

 

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.

 

Thanks for the info guys!
