Get a new hotter stat and a candy thermometer at your grocery store & see what coolant temp you do have. Get the eng coolant temp squared away then back flush the heater core and a garden hose/spray nozzle will work just dont use full psi. Make sure the heater hoses are on the correct nipples and the heater controls are positioning the doors where they should be & same w the vacuum servos if used

dummy gauge maybe...Do you have the correct radiator cap on it? Perhaps you aren't building enough pressure to start cookin' the coolant. If your thermostat was stuck closed you would boil over the block because it won't cool down. If it was stuck open you would at least get a lower than normal hot temperature. Can you grab the radiator hose with your hand when its been running for 10 minutes?

1/4 scale should be enough to get heat, your heater core is probably plugged.... Disconnect the hoses & flush the heater core,,, A garden hose works well for this.... If you still get no heat try partially blocking the radiator with cardboard behind the grill..

If the heater core was plugged, wouldn't it run HOT??? In my experience, Mopars have always ran on the cool side according to the guage. Ae there other issues that you assume are related to your low temps???

If the radiator were plugged it would run hot, the heater core is completely unimportant to cooling & if plugged coolant flow is un-effected..

My '88 Gran Fury police car barely gets to the 1/4 mark and has heat. It never passes the 1/4 mark even on the hottest Florida days. Like others have said, feel the rad and rad hoses. I agree it is probably a heater core or blend door problem.
Facts are stubborn things.

Check the valve for the heater also.Those had vacuum problems and especially the control head in the dash.I replaced a bunch back when they were daily drivers.Check the heater hoses.Both should be hot.GMs were great for no heat with the crappy DexCool plugging the heater core.Rocky

If both are hot Id say its a vacuum problem.The hoses usually break and loose vacuum to the control head.That or the head itself.Not a real hard system to fix.Rocky

OK, I see my mistake in reading the subject/question and responding to the OP (my apologies).
