X AUTOHAUX Car AC HVAC Oil Dye Injectors Kit Compressor Manual Tool 30ml/1 Oz

As soon as it was hooked up to the ac port it just blew the plunger out the top and the dye went everywhere.

Muy buena compra, muy útil.

Bueno funciona bien

It is what I needed.

I have done anything like this. It is plastic so take it easy. I had to use all my strength to push the die with a little oil. Not all will go in plus what's in the hose. It was enough to work. I ran the engine for a couple minutes. Then I changed high and low pressure switched. The slight release of pressure put yellow die around both connectors. I used my black light flashlight and it was so bright. I wiped that die off and searched the entire suburban for leaks. Happy to say, no leaks anywhere. For home use it's okay but don't expect to use it often.
