Where is the thermostat located on a 1996 honda accord?

The thermostat is located in the housing where the *lower* radiator hose attaches to the engine. I don't know why Honda does it that way. The upper radiator hose housing has the bleed nipple - you must bleed the air out of the system every time it is refilled but you can't do it at the radiator. Open the bleed nipple 1/2 turn when the engine is cold and close it when a steady stream of coolant comes out. We need to know what the overheating conditions are. If coolant is disappearing, look for the cause of that. Besides the hoses there is a flat spot on top of the radiator where a brace passes over it - look for a hairline crack running the length of the center of the flat spot. If that is okay, remove the radiator cap when the engine is cool and start the engine. Pinch off the hose to the reservoir and put the palm of your hand over the radiator neck where the cap was. If you feel steady pressure rise within 5 seconds that is bad news for the head gasket, otherwise you can rule that out as the cause. If it overheats at idle and cools off rapidly when you get going, even after bleeding the system, check to see if the radiator fan is running when it overheats. The fan, the control relay and the sensor are all common failures. Be aware one of those fans is the condenser fan... turn on the A/C to see which one starts up with - that is the condenser fan. Otherwise, if it gets hot on the road or gets hot and never cools down (but is not losing coolant) the radiator itself is the main suspect. If tap water has been used to dilute coolant you can be sure the radiator is hopelessly plugged with hard water deposits. You an check that by removing the radiator hoses and putting a garden hose in the top fitting. The radiator should easily pass all the water the hose can put out.

Follow the large hose on top down to the engine. Where it connects is where you find the thermostat. If you are over heating you may just have a bad fan, a bad water pump ( Broken Impeller) or even bad timing.
