my 93 camry v6 is overheating while idling

[gushie]

my 93 camry v6 overheating,it just started today,i jacked it up on the driver's side(left hand),just under the drivers door.i turned the engine on and left it idling while i was checking my exhaust underneath because it's leaking and giving out an annoying sound.while i was under the car,i noticed a spray of coolant coming from that overspill horse(is it the correct name?) to the ground.i then getout from under the car to see what was happening,i noticed the engine was overheating,the temperature gauge was in the red.
i thought it overheated because it was idling while it was tilted,the coolant couldn't go all around the engine bcoz of gravity.thats what i thought.i took off the jack,i left it to cool down and then added more coolant. but the problem is still there,if i idle for like 7-8 minutes it overheats even on flat straight surface.if im driving its alright

is there anyone who can help

When the car is idling and getting hot are the fan(s) coming on?

I expect you don't notice it when you're driving because the forward motion of the car is enough to pass sufficient air over the radiator to cool it. Especially if it is cold outside.
