excellent results

When out of state a Chrysler dealer gave me a $3000 estimate for repair of my Town & County’s 2 zone AC system. My first can of Red Angel stop leak had to be replaced (faulty release button). The second worked fine…4 months and no problems. Two tips: pressure drops as you add freon simply mean your condenser is working; and you need to add plenty of freon for cooling to begin. Auto Zone loans pumps to evacuate your system.


Claims by other marketing groups have been disappointing. Your product worked well from the outset and system is better than at any time I can recall.

Fix it

It seems to be working for now. Time will tell for I had a slow leak and from what I have been told this is the bomb. Cross my fingers I have faith in it.

Super Easy to Use

Super easy to install and works as advertised. Perfect product..

I have worked in the refrigeration field for some 40 years (Retired now) I doubted this stuff would work but did’nt want to spend $1100 on my old work van to replace evaporator.(I had the equipment to evacuate and re charge the system.)It has been about 2 months now and AC is working great. I’m astonished!” – Amazon Customer
