The Total Leak Stop and UV dye kit was a major disappointment. I followed all the directions to the letter, yet it failed to stop any leaks in my car’s AC system. The dye didn’t help me identify any hidden leaks either, which rendered the product completely useless. I was hoping the dye would reveal any potential issues that were hard to spot, but it didn’t glow or show any signs of leaks at all. The leak stop didn’t seal a single one of the leaks I was dealing with, and my car’s air conditioning remained just as ineffective as before. I even took it to a mechanic to double-check, and they confirmed that the product didn’t do anything. The canister itself was hard to use and didn’t fit well with the AC system connectors. Instead of saving me time and money, this product ended up wasting both. I would not recommend it to anyone who is serious about fixing leaks in their vehicle’s AC system.

Used this on my 2016 Honda Civic and it sealed up everything now my AC works for the first time since purchasing the car two years ago. It works wonderfully!

I read where some people had issues but there were not many choices so I gave it a try. I had no problems, put it on the low side port started the engine and turned the ac,I pressed the button on the top and it went in with no issues. After that I charged the AC to the proper pressures. One week later no leaks AC is nice and cold.

Needed to return, amazon will not. Manufacturer is not the seller, third party seller. The phone number is to manufacturer, they will not help. Ended up keeping it, not sure if it is good, I have no idea if I will ever use it.

It was hooked properly to the vehicle and made the entire system leak all the refrigerant as it dumped on the engine dye and sealer that should have entered the system. Amazon shows a return possible before aug 11 but don't give the link, only the tech # of the distributor.

It's good and for the price it's great. I had a leak in my car and my air conditioning wasn't working and this helped me a lot this summer.

Followers the instructions and ended up really working. I didn’t recharge right away though because the weather cooled. Once I did it held the charge. Very Hard to press the valve!

Worked well and easy to do. Unfortunately my condenser had a larger leak than expected.

I also found that it did not fit my low pressure connector (1999 Land cruiser)Tried pushing straight on, nothing.. tried pulling back collar.. which just released coolant gas and still wouldn't fit on.. Will try again later - but oh dear!

We fitted a new ac pipe to the car and got it recharged by a garage and it only lasted three days. So we bought and used the ac leak stop, then refilled the system and it’s been working ever since. It’s so easy to use.
