If you can't find a thermostat, you should forget about changing it or whatever else you had in mind after you found it. They've been in virtually the same place since the 1930s or earlier.
When you service the cooling system.

On a 2005 GMC Jimmy, the thermostat is located in the engine compartment, typically near the engine's water outlet. To access it, you usually need to remove the upper radiator hose that connects to the thermostat housing. It is often situated on the driver’s side of the engine, near the intake manifold. Be sure to allow the engine to cool before attempting to locate or replace the thermostat.
The thermostat is inside the housing, it is on the motor where your upper rad hose connects to, hope this helps
Left side along the frame rail.
I had the same problem with my 98 jimmy I repalaced the water pump have had heat since.
remove the 2 bolts that hold the thermostat housing to the intake manifold which the upper radiator hose attaches to the housing then just pull the thermostat out and replace.
