Wont hurt anything, but also is not very effective. The reason it is not very effective is that there is very little circulation in the air system like there is a an AC system. The dye becomes suspended as an aerosol in the AC circulation. It takes circulation to distribute the dye.

Get an Infinicon - you can HEAR the leaks and diagnose them - best $$$ I have spent for tracking down air leaks…

I agree with pairodice "Get an Infinicon"
I bought one and as soon as I opened the engine access on the curb side I heard a whistle coming from the air separator.
I couldn't feel the air coming out of the bottom plug or from around the cylinder near the top but the leak detector alerted me before I leaned in to search.
It wasn't cheap but it works.
