Pics of the truck, please.

My first guess is that you still have air in the cooling system. What does the temperature gauge show when you are running the truck on the road?

Welcome to your first post since joined over a year ago.

Suspect that @Joseph Garcia could be right but I wanna know why you were changing the thermostat in the first place?

Did you per chance install thermostat backwards or is that not even possible? Water pump problem? That is why I am curious why the thermostat was installed in the first place.

Make sure you burped all the air out of the system. These things are notoriously hard to get all the air out. You didn't mention if it was over heating or not either.
