5.0 out of 5 starsSupercool=Great Flush and no residue like others, filtered and reused it to clean out my evaporator
Reviewed in the United States on June 30, 2020
Replaced my AC system in 94 Grand Cherokee but needed to flush the old Evaporator at the engine firewall (Evaporator is hidden inside behind the dash) Used my flush gun and blew this flush into the evaporator - on my 1st run I got some tiny black particles - see picture (I think these are just corrosion & not the black death material you hear about). I was shocked to see these particles but when I put them on a white background, and they dried out, I think they were just corrosion coming off the inside the evaporator - I was thankful I cleaned this out before charging my new AC system and running my compressor.
I needed to flush this several times, to get out all the tiny corrosion particles, so I flushed into a container then filtered the flush and reused it - I was able to flush my evaporation about 10 times, by filtering & reusing the flush, and got evaporator squeaky clean - the evaporator was the only old part I needed to reuse as I replaced everything else.
Supercool AC Flush evaporates quickly and does not leave any residue. Most cheap brands sold at auto parts stores will leave residue and you never think you can get it out of the system.
I have been using my AC system, in Las Vegas summer heat, for a couple months and working great (with all my new AC parts I am getting a 50-60 degree differential to my vents and could not be happier).
In my opinion this is the best AC flush out there right now - evaporates quickly and does not leave residue.
