However, "at the upper hose connection to the engine" is a bit vague. To be sure, you'll need to look closely at the engine block where the upper radiator hose attaches. The thermostat housing is usually a separate metal housing bolted to the engine, and the upper hose connects to that housing. The thermostat sits *inside* that housing.
It might be a little tricky to spot without knowing exactly what you're looking for. A picture or diagram specific to a 1995 Honda Civic engine would be very helpful. You can find these diagrams in a repair manual (Haynes or Chilton are popular options) or online through a site like Honda's service manuals website (often requiring payment).
