Review: Excellent Product, think it through before use. - For £20+ I would expect instructions! Yes I can go on YouTube, the issue with that is its full of clueless "wanabees". If your system is fully charged you will not be able to press the plunger, in fact because the fitting doesn't appear to have a one way valve you will have a lethal projectile from the back pressure. No gas in the system and the compressor will not kick in so running the engine for 30 mins will just add further expense and achieve nothing. Having instructions would prevent any mishaps, ideally I guess a half charged ac system would be best. All that said, and little common sense, my system was fully charged and the condenser leak minor.....I attached a G clamp to my syringe to prevent back pressure and slowly closed it (I couldn't have done it with my hands). Why 5 stars? Because the results were excellent, just give some thought to the above before going 'gung ho' potentially covering your engine bay in blue dye or worse still taking your eye out. Excellent stuff for condenser pin holes.
Review: Great product easy to use - Great product, easy to use, some reviews saying system shouldn't has gas in it but that's nonsense how else is the product meant to work? Start engine , turn ait con on fully and clip on the adaptor to low point adaptor self seals so there's no gas leak, then inject the product, yes it's had as you are pushing against the gas pressure. Total job took 2 mins. I dont know it my leak is small enough to be fixed but the product is easy to use.
