can I put coolent dye in the car to see if I have a blown head gasket because I don't see water in the oil or oil in the water but I do have air coimg in from some where?????????

As long as you have the light and glasses. I've seen the kit at PepBoys.

better off pressure testing the water system.... its a lot less complicated, i think autozone might do it.

Autozone doesn't pressure test. However, they do have the pressure testing kit you can rent. Pay a deposit, and when you bring it back, you get your money back.

yeah...i have my own kit, but it will deff be less messy if you do it that way.... fill it up with water...pump it up and see where it leaks at, if the pressure doesn't drop then no leaky leaky
