    Interestingly enough, I've seen this before.
    For various reasons, some coolant leaks will only show when the vehicle is thoroughly heated up. Others only show up once the engine is stone cold.
    Due to the use of so many different materials employed during manufacturer, there is no predicting what will leak nor when.
    Intermittent conditions require whomever is inspecting to take into consideration that there may not be a leak, but surely there will be evidence: coolant stains, etc. You could help in this by trying to ascertain exactly where on or under the car you see coolant, if any.
    What exactly are you seeing when you say it's leaking? Puddles? Reservoir level low?

    There is a puddle under the car. The reservoir is full and then when its cold there's a puddle and the reservoir is completely empty. It looks like the leak is coming somewhere from the passenger side of car just right of the tire. It only leaks when it wants to . It does not leak everyday that is is cold, It's a stuburnn little car.

    It may be that the reservoir is cracked and leaking.
    Checking this out locally seems the only thing to do and it shouldn't take long. (Where is the car?)
    You may perform a close visual inspection yourself. Use a good light and just look closely. Check the hose that goes to the tank, too.
