What temp thermostat did you put in it?

don't know, they told me that's the only one they sell.

It should be stamped on it. Its needs to be a 190* stat.

Just because you got a new thermostat, doesn't mean you got a quality thermostat. I've had similar issues on 12v and 24v engines. Spend the coin for the newest style genuine Cummins thermostat and have heat in short order (usually about 2 miles of light driving for me.) I'm also a believer in the HD purple antifreeze helping, but I don't have any real side-by-side proof to back it up.

i got new t-stat from cummins part-3928499 but it did not fit my housing

 

[not enoughsmoke]

depending on ur motor some have small thermostats and dodge p-pump one have those

 

[Pyccak]

i have 1995 dodge ram 12v cummins p-pumped engine, and it did not fit housing is to small.

That's the correct part number for that application.

my truck dose the same thing drain about a gallon of antifreeze it should do the trick. I run no fan in the winter and take some antifreeze out and it just gets up to temp.

all my temp issues were from the t stat, i even got a genuine cummins t stat that acted up on me right out of the box, had another one suck that rubber ring into it making it stick open

 

[Pyccak]

Good deal, but what fixed it? Too many open ended threads when people are searching for a solution later...
