Engine is running cold, Is this normal ?

[jnjlizak]

I live in Vegas and the temperatures have began to cool down. I noticed that my 6.0L has been running extremely cold as far as my temp gauge indicates on my dash. I took a picture just after a 15 mile drive on the freeway doing an average speed of 70 mph. My heater was set to 72 degrees inside the cab. My engine coolant temp gauge barely came off of the bottom line. It was 42 degrees outside during the drive. Is this a normal condition, or do I have a potential problem that needs to be adressed ? When it's warm outside, 70 deggrees or higher the temp gauge rides right in the middle where it should be.

Replace the thermostat. That will get you fixed up.

What is the process of changing the T-Stat? I know where it is, but what about draining out some of the coolant?

only the coolant that is higher than the tsat will fall out
