Where is the thermostat housing location on a Chevrolet s-10 pickup with 6 cylinder gas engine?

The thermostat housing on a Chevrolet S-10 pickup with a 6-cylinder gas engine is located at the top of the engine, on the passenger side (right side when looking at the engine from the front). It's typically where the upper radiator hose connects to the engine. It's a fairly prominent part, often made of metal and containing the thermostat itself.
