Detecting a coolant leak

I know I'm leaking coolant (seen it on the driveway and my coolant level was low) but now that I've jacked up the front-end, I don't see the leak! I let the car run for a good 15 minutes, turned it off, and nothing leaks. I wondering if it's the angle the car's sitting at, although my driveway is sloped as well.

Are there any tools for putting pressure in the a4 coolant system to expose a leak or any other techniques?

Thanks,

-Bill

On my '98 2.8 QM...

I had a coolant leak, but it rarely showed below the vehicle. I could smell it cooking off. I solved the leak by replacing the coolant recovery reservoir - engine bay looks much better, too - and replacing the hose clamps to the reservoir with worm-drive clamps. Haven't lost a drop since. Reservoir was ~$30 at the stealer, I believe.
