I have a 93 Ford Escort started over heating, I have changed the thermostat, no coolant in oil, no smoke ?

I do not see any leaks, but if you drive it and look, there is coolant all over the motor. Also with a new thermostat, the top hose is still hard, like the coolant is not flowing. Help anyone.

If coolant is seen on top of motor ,possible one of the small coolant hoses that preheat the air intake plenum is leaking.Do you see any oil floating on top of your coolant inside the radiator? Another thing is when starting the cold engine see if the radiator hose gets hard quickly.This can be a sign of a head gasket leaking compression into the cooling system.No coolant in the oil doesn't mean you don't have a head gasket blown.The leak can be only 1 way, from cylinder to cooling system.Just depends on how bad head gasket leak is. Another thing it can be is cooling fan or the thermostatic switch which usually screws into radiator.Or the fan relay. Hope this helps you.

Have the radiator flushed it is that old it a good Idea.
started overheating hmm...back up ck your work thermo installed with no cracked housing? and look at all hoses...heater hoses..small hose for cracks.....You need to find out where coolant is coming from..is the engine boiling over out of recovery tank or radiator? You need to find source of original overheating.....and hope its a hose somewhere...ck them all....good luck!
go to advanced or auto zone and borrow the coolant pressure tester, it hooks onto the radiator, look at the radiator cap for psi, like 12 psi or something like that then pump the tester to 12 psi and you will find your leak, if it has no leaks then the pressure will hold, watch the gauge
