160 degrees should be hot enough to get some heat.
You could check the engine temp with a scanner to confirm.
I would double check the blend doors, and the temp of the coolant in and out of the heater core. I use an inferred temp gun.
SOURCE: Cool air blowing from heater, even when on high.
if the heater core is bad, it will leak or not flow water. even tho you can "hear" the blend door working, it may not be actually moving inside the box. check to see if the actuator is connectd to the blend air door. You may be hearing the actuator moving but not the door.
SOURCE: 98 dodge dakota slt 318. no heat, low operating temp
First thing first, turn off the engine wait for 15 - 20 mints, open the radiator cap and fill it up to the top then start the engine and see if it needs more water adn add as needed, then wait till you ca see the water circulating in the radiator now instead of corculating if it starts boiling out shut the engine replace the thermostat and do the whole thing again.
unless there is water in the engine the gauge will not be able to show the actual temp of the engine, so always malke sure you have water / antifreeze
SOURCE: Temperature gauge almost redlining
What engine does your Ram have? This could be an indicator of a bad head gasket. If the sensor for the gauge is truly bad, the only way test that theory is to install an aftermarket gauge, use an infrared temp sensor on the water outlet hose or replace the coolant temperature sensor. If this doesn't help, you may need to take it to a mechanic and have them do a leakdown test. Failed headgasket can cause bizarre overheating issues. Good luck.
SOURCE: 2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat
Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.
SOURCE: BOTTOM RAD HOSE COLD TOP HOT. ENGINE TEMP ABOUT
Did you burp the air out of the system after changing those parts? It sounds like the thermostat isn't opening which is why the lower hose is still cold. Click my screenname, go to my tips and tricks, and choose the one about burping the cooling system - it may help you out.

You would think that 160 would produce heat but nothing, removed dash last night blend door is opening and closing , like I said both heater core hoses are hot so system is circulating but no heat..
