[V8] Trouble finding a coolant leak

[George Tur]

I have a question about tracking down a coolant leak. 

Over the past month my V8 has been losing about half a pint of coolant per 
week. This past week this has increased to where I have to replace about a 
pint every 2 or 3 days. I've looked for leaks and can't find any wet spots, 
or smell anything inside the passenger compartment. Is there a way of 
tracking coolant leaks using dyes like they do for oil leaks?
