Looked at the how to install for thermostat and understand direction of install.
My question is
Do you just slide it into the end of the upper radiator hose nearest the engine and it stays there on its own?
I am familiar with installing in older cars that have the thermostat housing that hold it in place.
I do have the FO4 shop manual but didnt see anything that gave specific instruction and want to do it right the first time.
