Liqui Moly3339 Fluorescent Leak Finder 50 ml

The media could not be loaded. Great product, does exactly what it says it will. Within moments of putting it in the expansion tank of my car and shining a UV light on it, my red coolant appeared to glow like radioactive waste, returning to its normal colour when the light was removed.Easy to see in daylight and especially at night, the coolant leak I have will have nowhere to hide. Used a lot of products by this company and never had any issues with any of them.

You need to get a torch to go with this stuff but it's very very good.You just need to remember to pour it accurately as if you spill it the shine will potentially ruin whatever leak you were trying to detect.

Really useful and easy to use, helped speed up locating a odd oil leak on a hidden part of an engine. Used with a small UV torch which was also another value for money purchase for Amazon. These 2 items are essential for any DIY mechanic.

this stuff really works top product

Great product, made it extremely easy to find a small leak beneath the coolant bottle. And (a few months later) another leak beneath a coolant flange!Use in conjunction with a tool to pressurise the coolant and of course a UV torch to reveal leaks with ease. Mirrors can also be helpful to locate leaks behind/beneath parts that are otherwise impossible to spot.Quick and easy to use, highly recommended!!
