I have a 1995 ford aspire its steaming at the radiator,changed cap already temp gage is normal

If your antifreeze is boiling, at the moment, I don't trust your temp gage? Does the radiator fan work? Any applicable trouble codes? Can you check for coolant flow through the radiator, cool engine. Check the thermostat and coolant temp sensor. If you could do a little testing it might help narrow things down, a little.

Toyota corolla 1993 water pump leaking and steam coming from top of radiator. added chem and weld solution to radiator recently

Since the water pump is leaking there is low action of the water pump to circulate the water into the engine jackets and the radiator.
So you need to remove and overhaul or replace the water pump, replace the gasket, check the radiator for leaks with high pressure test, replace with a good cap and the fault of heating and steaming will be gone. Also check the timing of the engine, do a tune up.

Radiator overflow steaming when driving 15 to 20 mile distance, don't have a manual to see if there is another location to put in radiator fluid or water, temp is normal, and nothing seems to be leaking,...

Yes, the cap could be it. But, I would also check the strength and concentration of the antifreeze/coolant to make sure it's 50/50.

Also, check that the fan is coming on for the radiator, even though it may seem to not be overheating.

Good luck on this repair.

Bought saturn SL 2000 at auction, drove it home and it's steaming out of radiator cap, filled with new antifreeze and bought new cap, appears to be leaking out and there is a light on on the dash of course...

The light is letting you know that the engine is oveheating. You did not mention how many miles are on the car, so the over heating could be a number of factors; Thermostat is stuck closed, cooling fan is not operating, radiator is name a few.

Fluids are spraying out of my radiator, it's kinda steaming/smoking, and the warning light on my dash lit up. what do i do?

You may have a blown head gasket or a coolant leak and the water was low enough to over heat.

Top radiator hose is HOT, radiator is steaming

have u replaced the radiator and hoses? Thermostat could also be stuck open. Water pump could also be your issue. with motor cool and of remove radiator cap(cap may be bad as well) top-off fluid and start car check for fluid flow with flashlight. Water pumps typically leak from what is called a weep hole when the shaft seal fails. Yours will be located under the timing cover (drivers side) running of the timing belt.
Hit me up after u have check on these.
