CLIMASET - Full KIT AC R134a 4in1, Gas Replacement, For cars 1994-2016 - Air conditioning solution, Standalone application - Complete set - Sealant, UV Colorant, Refrigerant

Worked perfectly for my 9 year-old Fiat 500.No leak, but it had lost sufficient refrigerant via the seals over the years to trip the pressure switch and prevent the aircon working. As soon as I gave it a few more PSI, it all started working again. I juiced it to 35psi.The kit works well, just remember that the valve works in the opposite way to a tap. Also remember to cover the end of the hose with a rag before unplugging it from the car. otherwise UV dye sprays all over the car engine and that makes it impossible to locate a leak with the UV pen since *everything* glows....! Easy to use and works well.

It worked for a day , I don't know the exact reason but better to get inspected by a professional .

Wanted to diagnose where a leak was, that was requiring seasonal refills, on a 13 year old Astra, and this appears to be the only UK option, at present, that contains UV dye, even comes with a UV torch, for those without one.Trivial to add the dye laden gas to the car, turn on ignition, turn on AC, open vents and turn up to max, and leave running for a few mins, while you grab some gloves, some goggles / glasses, and some clothes you don't mind ending up a bit stained. Retract / unscrew aerosol seal piercer, on the supplied hose, screw on to can (but don't pierce seal), locate and remove dust cap from the low pressure port on the AC pipes, clip the can's hose to port, screw piercer all the way into can, to break seal, then back off a few turns to let the gas flow, and wiggle can for several mins, till it feels more or less empty. Check pressure on AC is in the green, on gauge, screw the piercer all the way into the can to mostly seal one end, just in case, unclip from the AC port carefully, as the last bit of gas and dye in the can's hose will spray as you disconnect. Check air temp on vents, then drive around with the aircon on for a day or two. Then at dusk / dawn / in a dark garage, use a UV torch to look for florescent yellow dye between where the high and low pressure pipes disappear through the bulkhead into the car, and the compressor and condenser (radiator). Found a spray of yellow dye from both ends of a rubber pipe that joins two metal sections of the low pressure line. If the leak stop element doesn't work will have to replace the whole pipe due to that rubber section being crimped on :(

Did the job.

Very easy to use. Got the air con working again in under 10 minutes !! I was lucky it had stopped working due to slightly low pressure! If there had been a leak it would not be so straightforward.

Easy to use ice cold car just in time for very hot weather

For this to work YOUR AC SYSTEM MUST BE FULLY CHARGED. Why? To create a vacuum within the system that draws thr refrigerant into the pipes. If you have a leak there wont be enough pressure to draw the climaset into your system

Great product, easy to use, didn't see any leaks under UV light so hopefully it's legit :D
