Should be at the engine end of the upper radiator hose
The thermostat on a 4.7L is under the housing where the lower radiator hose hooks to the engine.
Try in the housing at the engine end of the upper radiator hose
Usually in a housing located at the engine end of the upper radiator hose I have an 01 Durango with a 4.7 and the thermostat is in the lower radiator hose at the engine end.
Contrary to every other car and truck that I have worked on, the 2004 Dodge Durango has its thermostat located on the bottom radiator hose. A close inspection of the bottom hose where it connects to the engine will show you the thermostat housing.

The thermostat is located on the bottom of the the timing cover. crawl under the front end and look for the hose and housing. Its right in the front of the block.
You can find the 1991 Dodge Shadow thermostat in the thermostat housing. The thermostat housing will be on the front of the engine.
On a 5.9L the thermostat is under the housing that the upper radiator hose hooks to on the engine.
Follow the upper radiator hose. Where it attaches to the engine vertically is the thermostat housing. Remove this to access the thermostat. This job is easier if you first remove the alternator and its upper support bracket.

The thermostat is located on the front of the intake manifold. Follow the upper rad hose to the manifold. It drops behind the alternator. Not a fun place to work but you can remove the thermostat housing and hose connected together.
It is under the housing where the upper radiator hose attaches to the engine.
