If your temp gauge reaches 195-200 the thermostat is doing it's job. If your coolant level is at the correct level you may have a problem with a partially plugged heater core, replacing it is not a job for a DIY mechanic.

2017 truck - hope it's hater isn't clogged!
The heater baffles me. Our car (similar eng) has been sitting about 3.5 hours in the 40's today. I got in, started it and after about 15 seconds I checked for heat. Yep, it's blowing slightly warm air.
How the heck does it warm up so fast?

Is your engine temp gauge indicating where you expect it to be?

Temp "gauge" is in the middle of the dial ... Will try to remember to check the digital readout in the menus next time I'm behind the wheel. no CEL or messages waiting from the computer

For body type codes, your display wont show them.
I had a blend door motor failure and nothing showed for me but the dealer was able to see exacty what motor was bad by the code.

Maybe you've got a bum thermostat. If it's stuck open it could cause this.


Possibly low coolant too.

Low coolant almost always results in low heat output to the cabin... at least in my older Chevy trucks that was the culprit

I have a 2003 dodge diesel that it takes 5-6 miles before it starts to warm up, but it is fine after that.

OP has a gas motor. Regardless of what the issue is, I guaranty it has little to do with the operation of the heater in a 16 year old diesel pickup.

So bee more specific. Check the actual coolant temp and describe the conditions in which it takes a while to get warm....I.E., it's been -20deg up there.
Truck outside?
Plugged in block heater?
Was it fine last month when not so cold?

Once you can check all those boxes, start looking for a problem if everything else is as it should be.

He's talking about the digital temp reading.

I doubt you have any mechanical issue with the engine or cooling system. You probably have a blend door that is not completely closing, so the hot air from the heater is blended with cold outside air.
