InterDynamics Certified AC Pro Car Air Conditioner Leak Detection Kit

Daniel Shaw: Easy to use, pour in and wait for your leak to show. I used half a bottle and was more than enough to show where my leak was. I kinda had an idea so that may have helped but the dye really glows bright! Take the guess work out of find a leak. Highly recommend

Covfefe: This is totally worth the money, finding leaks was so easy to track down BOTH oil leaks and radiator fluid leaks on multiple cars. Before, I’d foolishly pour the whole bottle in. You don’t need to, the black light makes it pretty obvious and doesn’t seem to degrade over time. So if you can’t see it, you can always add a little more in to save money.

hans: Worked perfect. After major engine repair I am still having antifreeze consumption. Mechanic blaming it on everything else besides his lack of getting head inspected for cracks or warpage. Put this in antifreeze.. Put paper towel over exhaust ran engine for 30 min.. And sure enough, uv speckled across paper towel. Now mechanic willing to pull head... After showing him uv specks on towel and on spark plug. What a pain in the a$$...

dc722: I ordered the UV dye and a $9.00 uv flashlight from amazon to troubleshoot a very difficult leak in the cooling system of a fiero. I could see drips of fluid on the frame under the engine, but I could not find any evidence of leaking hoses nor any solid evidence that the leak was coming from the water pump.

Just to be on the safe side, I used 2 doses of the dye in the fieros cooling system since it holds about twice as much coolant as a regular car. I waited until dusk and examined the engine with the uv light. The dye showed up bright and clear and I was able to quickly rule out hoses and water pump as the source of the leak. The leak is in a very difficult to view area of the block and behind a heat shield, so I can't get a direct view of the precise place it is leaking, but the drips of dye leave marks even after the fluid dries out so by process of elimination it appears that I have a leak from the head gasket. If I had better access I have no doubt I could see exactly where the leak is, but that would require some disassembly and possibly putting the car on a rack which I haven't done yet.

All in all, this stuff worked great for finding a difficult leak. The...
