Review: GOOD PRODUCT and, an inexpensive way to resolve an evaporator leak. - I admitted, I was a little skeptical about the effects and effectiveness of this product but, I am impressed. A leak on the evaporator coil is the last thing you want to hear when facing with an Auto A/C issue but, if you are interested this situation, concider using this product. Easy to install and after more than 6 months, it's holding pretty well with no side effects noticed.
Review: Would not close up a thumbtack pinhole in an evaporator - Purchase two of these for my wife's Toyota Camry and it did not work. We ended up taking it to a local AC company and had the dashboard removed in the evaporator replaced. When the tech pulled the evaporator I asked them to locate the hole that was in it. How do we know the evaporator core was leaking because the condensation line had the dye coming out of it. After putting this into the system using two different tubes the pinhole was never blocked. And I say pinhole because the hole that was inside the evaporator after it was all completely cleaned was the size of a thumbtack pin. So it did not work it was a waste of money

### ⭐⭐⭐⭐⭐ Works Great
*by J***. on July 29, 2026*

This worked great for the small leak I had in my 2016 Tacoma. Using this sealant with a fresh recharge of refrigerant made the A/C very cold and like new. Use the green adapter for R1234yf and the black one for R134a refrigerant. Run your engine with the air conditioner on for about thirty minutes after though to circulate the sealant.
