I bought 2 cans of this to solve an ac leak with my saab 9-2x. I filled one can which leaked out. I located the leak using a uv light and yellow glasses. A gasket at the compressor had gone bad. I replaced the gasket and loaded up the second can. The new gasket held and she now blows cold. This product served its purpose well. I like that this product doesn’t contain stop leak which can harm ac components.

It’s a can of refrigerant, nothing too special there. But I can tell you that the dye it includes is BRIGHT! You could probably spot this stuff without the UV light, but I have no doubt that it will absolutely glow when the time comes to track down the leak. My only hope is that the manufacturers did their homework and sold a quality product that will not muck up the A/C system, only time will tell on that one though.

it works but be careful when putting it in top can leak

When I bought this, I wasn’t aware of a need for a pair of UV-sensitive yellow glasses. But, I decided to give it a shot without them and then run out to a local place and grab a pair if necessary. I’m glad I didn’t get the glasses. This stuff fluoresces PLENTY well to be seen by the naked eye under a black light. That was the upside. The downside (?) is that I didn’t actually have a leak in my system. The only trace of the dye was right at the connection point and was, in essence, overspray from connecting and disconnecting the can. That said, if you do suspect you have a leak in your AC system, you should feel confident that this would help you find it.

I got 2 cans for my truck and the wife’s car. Both went great and I was able to exactly find the leaking part. This stuff flows bright neon green when illuminated by a UV light. I would recommend getting the kit with the glasses as they do make the uv dye pop out at your eye even more. Don’t waste time guessing what’s leaking, throw a can in and see where it’s leaking quickly.

I bought this item to find a leak in my vehicle AC. This product works great. The product shows a bright green color when released and is very visible when using the special glasses and light needed to find the leak. The color stayed so there was no fear of it disappearing before I completed my search and I was able to locate the problem. The price of this product is reasonable. I would recommend this item. It was delivered timely and well packaged.

The A/C in my bimmer started blowing only cool, not cold air. I didn’t want to use anything with ‘stop-leak’ in it after hearing warnings from others. This is pure R-134a plus UV dye, no stop-leak. Instead of these all-in-one kits with a UV light, I bought a MUCH better UV flashlight that is really bright and they are surprisingly cheap to buy.It’s easy enough to use. Get a hose with an included low pressure gauge, start the car with the A/C on high, and hook it up to the low pressure fitting on the car and screw in the can on the other end. Before puncturing the can with the twist knob, look at the reading to make sure it isn’t already high. If you have a leak you should see a low reading. If not, it may be something other than a leak.I haven’t found any leaks yet, but the air is now colder. So in my case it’s probably leaking from the evaporator, which is under my dash, *groan*. That means the whole dash has to come out to replace it, an expensive repair if a shop does the work, but it was worth a shot to check for other causes.

Had a Freon leak in my 06 Sequoia somewhere. Couldnโt find this Freon with dye, so of course I went to Amazon!! It did itโs job…it was leaking at the condenser. Note: you need a UV flashlight or some type of UV light to detect the dye…..obviously…!!!
