Mastercool 53351 Professional UV Leak Detection Kit – 12V High-Intensity Light – Detects A/C, Coolant, Fuel, Oil, ATF Leaks – Includes Universal Dyes, Glasses, R134a & R12 Compatible

This is a great set and the price is below $60 bucks. It is pretty straight forward and has usage label for each dye. If the dye happens to be same color as your coolant just go to local auto shop and buy alternate color. Do not put anything in your engine gas coolant or engine oil that is not recommended for the car. If you are not mechanically inclined leave it to the professionals. That said if you are buying this it is because you want to do it yourself. The kit works and you will be able to service cars a few times the best part of this kit is the UV light that connects right onto the battery. This means you never have to buy batteries and the cord is very long so you can see all over the engine. The kit comes with everything you see in the video and the major set back is to not have a case. The more expensive kits come with carrying case but that will run you extra $20 bucks or so. How to check for leaks 1. Your first step is visual inspection oil will flow down and backwards because of gravity. so start from the back of the car and move forward. 2. Look for highest point oil is coming from and that should be source of your leak 3. Clean the area of oil or coolant or what ever fluid is leaking with break parts cleaner and a paper towel or wd40 both work well for cleaning grease and oils. 4. Turn engine on again to see where fresh oil or coolant or leak is coming from this will help locate the exact spot for the leak. 5. If you still did not find leak manually then time for some uv dye. pour dye into fluid you are testing. (again you should clean area FIRST before putting in dye to get better results. be careful when injecting dye into pressurized systems so make sure to weak gloves and goggles. 6. Start the car after putting in dye and let the dye circulate through the system after 2-3 minutes turn engine off and connect your uv light and put on glasses and follow steps 1-2.and you should find your leak 7. Typical places for leaks are connection points hoses being cracked or broken, bolts being loose or seals being work, or maybe no leak at all just a sloppy mechanic who poured oil all over the place or didn't tighten oil filter. hope this advice helps if so please click the helpful link and let me know. and good luck with your leak job. this test works for any year make or model.

The kit is set up to test for different kind of leaks. It worked really well. The UV light flashlight is very durable and well built. The only thing that’s not clear from the instructions is what dye to use for power steering fluid (it’s the oil one) and how much to put in. I poured half the little bottle and it’s more than plenty! Probably should have went with 1/4 or 1/8th of the bottle. You don’t even need the special glasses with the amount of fluid I used ;). I found my leak, it was a small hose clamp, saved myself $2500 worth of mechanical work. So definitely worth it.

Fantastic kit very useful for all different types of leak detection

I used this on my Vintage Air system in my 1974 Dodge Charger. The kit I used was universal so I made the lines and I was able to find a very small leak in one the lines. It was because of a poor job by me when I crimped an end on. This made the job much easier than expected!

Can’t tell you too much about this kit not used yet but had the use of simuler kit and was happy with finding leak results
