Default Where is the thermostat located on a 1999 Honda Civic. ?

I looked under my hood and I think I narrowed it down to two places. There is one location where a radiator hose goes into it and it is mounted near the engine head on the side. It has two bolts on it. The other location is a little behind the engine and I think it has 3 or 4 hoses going to it and like 2 or 3 screws. I was hoping someone may exactly where its located or how I can locate it myself.

your first thought is correct with the two bolts

Your thermostat is inside the thermostat housing which you've described as the radiator hose connecting directly into it. See these photos for confirmation: luck!

it will be located on the upper engine block towards the firewall side, its usually between the head on the intake side & the engine block. follow the bottom radiator hose goes near if not under the distributor. yes has two bolts holding thermostat housing to thermostat lower body and its bolted by two other bolts holding it to the engine block. there is a metal pipe it travels from the thermostat housing towards the pulleys side of motor it connects to water pump - it has hoses that feed off it for the intake manifold/throttle body heater(for cold winter) and the passenger cabin heater. this pipe will have rubber "o" rings seals on each end. ** I INCLUDE PICTURES WITH NOTES ON IT SHOULD HELP....
