Coolant leak only at idle

[islandtuner242]

ok so i noticed my car slowly dripping coolant but only at idle when the car is in motion every thing is ok but once it is left to sit for a period of time i see a puddle of coolant on the ground.............. as i'm driving the temperature drops but once i'm at a traffic light the temp rises i'm lost with this one



Thanks in advance,
Kadeem

BUMP

i found out what the problem was the radiator has to be pressure tested it only leaks after excessive pressure is put on the cooling system (i.e speeding) so i'll see how it goes monday
