5.9 magnum too cold
Hello, I have a 2002 Ram 2500 with the 5.9 v8 that is not will not get above 130 degrees unless i fully block it off with cardboard, but when i cover it it goes to 215 degrees. I replaced the thermostat, and it still doesn't get above 130 at all. I drove it 4 hours and it will not heat up. I did replace the radiator this summer and it ran just slightly cooler. Does anyone know if it could be the radiator is cooling too good? The CEL is on for code 1281.

Code is for "engine cold too long." How old is the pump? If the radiator is new, did you burb all the air properly by jacking it way up on the passenger side? Have you checked the temp of the upper hose? How about the heater core hoses?
Even at 0 deg F it should warm up eventually, especially with a winterfront. I put one on my grille to heat up quicker with my 180 stat but it never really gets that cold here in the PNW.

+1 on using a Stant… they don’t cost much more, but the time and money you save by not having to replace it again (and again) is a win.
As a guess, I’d say the thermostat price difference is less than the cost of a second thermostat housing gasket, so even if you consider your time free, it’s a win.
