Just had a pressure test completed on my truck for any leaks that I might not know about. Turns out everything checked out ok, but just in case I still lose any coolant can a dye turn up anything? The reason I ask is that I may have an intake gasket leak that I might not know about. Thanks for any info, Andrew

The dye can only help if the leak is external. If the leak is internal, it wont help.

You best bet to watch the level in the overflow tank. If you have to keep adding, then you have a leak.
