I have a 96 honda accord 197k miles on it. For some reason it keeps overheating i'm trying to figure out all possibilities. So far i have did a radiator flush, new thermostat and new radiator cap. Any ideas on what it possibly could be?

Clogged radiator, inoperable radiator fan, blown head gasket, defective water pump, etc.

Just curious about the flush? Oil in the coolant. Water in the oil? Looks like a milkshake? Head gasket more than likely. A motor gets hot once and its garbage. Especially small ones. You can pop a motor in that car in no time.

First off, what were your reasons for the coolant flush? Was it overheating before that? If not, then I would say clogged radiator or defective waterpump. When was the last time you had your timing belt replaced? From my experience, it is likely the fan. Or clogged radiator. Sometimes the radiator can get clogged during a flush. You're moving debris around during a flush. It could clog a coolant line or your radiator if not done thoroughly. My 1999 Toyotas Camry had the radiator changed and started doing the same thing. Mechanic had to flush the system three times to get all of the debris and rust out of it, but that did the trick. Previous owner ran water in the car instead of coolant.

First the obvious is checked. You changed out the old rad hoses for new because hoses rot from the inside so a flap of rubber could be slowing down the flow of coolant. Next, there's sufficient coolant. The radiator is not blocked with a "Bra" or newspaper laying flat against the rad fins or the grill fins. Then your driving consists of mainly driving 30mph on an open level road
(if it is all hills going up, then the engine gets hotter)and you are in bumper to bumper traffic… And you do not hear the rad fan come on occasionally during these times.

Tire pressure is at normal pressure(not under-inflated).
Air cleaner is clean or new.

I'm supposing you checked all this out. And responded with the correct answer.

Then I don't know

See a mechanic and pay the big bucks.
