Heater not working top notch
#21
unhook both heater core hoses and take the item bellow shove it in one hose run water through it till turns clear. do the other hose. go back and forth till there is no more dirt water coming out (could take 10 plus back and forth). hook hoses back up and turn truck/ heat on. to start with i only open valve about half way or less (all the stuff in the heater core will slowly dislodge. gradually opening it more and more each time till complete. NEVER OPEN VALVE MORE THAN 3/4 OPEN probably would be fine but you never know. done this on about 8 dodges over the last few years for friends/ self. it will be nasty just so you know.

I use a water pressure regulator for RV's. The adjustable one...

Even, then, don't open it all of the way. Too much flow OR pressure is a bad thing.

Not to disparage any insights here, but my truck has never had a problem with bleeding the coolant system. I've had several t-stats installed and never bled, plus this summer I put on all new pump, hoses, and t-stat with a full coolant flush including heater core. Just closed it all up, filled it, and ran it til warm. Added coolant and was good to go. And this was on a flat driveway.
Maybe your t-stat is weak or heater core is so clogged it can't flow?

dodge heater cores get clogged over time. all heater cores do but saw it more in dodges than others when i was mechaninking my way through college (Don't really know why). like i said though i only have done 8 of these all worked out with the tool in my post on city water. some of the mechanics that taught me this blew up heater core from time to time but they were always in such a hurry they probably WOT that valve so ya be careful and that tool works great

I have. The biggest problem is getting all the air out of the heater core. Heater core is the highest point in the cooling system, which makes it an ideal place to trap air. (and it does a very good job of it....) Finding a way to purge the air is the *hot* ticket.
