ERRECOMCool Shot Ultra R134a+R1234yf+A Conditioner Sealant Car A/C Stop Leak

I used it after using Extreme Ultra. Which also worked great. I had my AC on for 20minutes to make sure it was as cold as it was going to get. I then installed Cool Shot and ran the AC for another hour. I logged a 7F degree drop in temperature. I am very impressed with this product

Helps get better performance out of the A/C system, it doesn't do miracles or fix leaks, but it improves a bit. When applying it, it is preferable to handle a route of at least half an hour so that the product can be better distributed in the system. I don't have a thermometer, but maybe the air dropped by 3 or 4 Celsius.
