Steam coming from radiator, but don’t know if overheating
I have a 2002 Dodge Ram 1500, 5.9L. I recently put an engine in it, because I locked the old one, and I didn’t reinstall the coolant overflow tank on the radiator. Whenever I drive the truck, when it gets heated up, it starts blowing steam out where the overflow tank would normally connect. I don’t know if the trucks overheating because my gauge cluster is dead. Before I put this coolant tank back on, I want to make sure it’s supposed to blow steam into that reservoir or if it’s overheating. I always stop the truck when I see steam

Why didn't you reinstall the coolant tank??
Coolant Reservoirs: What You Need to Know - AutoZone
COOLANT RESERVOIR
COOLANT RESERVOIR
A coolant tank acts as a regulating component to the excess coolant that’s produced from the heat in your engine. As the warmth rises, coolant expands and overflows into the coolant reservoir and is then sucked back into the radiator as your car cools down after shut-off. Your vehicle relies on your coolant tank to readily accept the excess coolant with each cycle, and a crack or leak means constant replenishing and the possibility of overheating your engine.

Google how the system works.
The overflow is also called the expansion tank. Yes, it collects heated coolant, which flows back into the radiator as it cools. Reinstall the tank. If you're not topping off coolant daily, you're likely overheating at some level.
