Thermostat stuck open and truck running cold.need help ASAP thanks

 

Also when I pulled thermostat housing there was a lot of white foam. Need help

 

Going to need more info.

What Trans?
What mods? (if any)
Is it speed related?
Any smoke? (if so what color?)
Did it just start or has it slowly gotten worse?
Did you just fill up with fuel?

The more info you can provide the better.

Not 100% but sounds like head gasket!!

Not sure how long u have owned it but same happened to a friend and his was head gasket. His must have been ridden hard and put away hot. When you get it fixed get a pyro on it and always cool down to 300deg on the turbo before shutting it off. It will reward you with long life that way.
