Where is the water outlet housing on a 1996 Chevy cavalier?

The water outlet housing on a 1996 Chevy Cavalier is located at the front of the engine, on the cylinder head. It's where the upper radiator hose connects. It's generally a fairly large casting near the thermostat. However, without knowing the specific engine (1.8L or 2.2L), pinpointing its exact location on the engine block requires a visual inspection. A repair manual specific to your Cavalier's engine will give the most precise location and diagrams.
