ERRECOM Extreme – 30 ml, Leak Stop for Vehicle A/C Systems using R134a Refrigerant Gas, includes Adapter for Low-Pressure Charging Port R134a

Lots of bad and thoroughly misleading comments on here by people who have not used the product properly. Add to a pressurised/full/gassed system (ignore silly comments about the system having to be vacuumed/empty). Start car and run aircon on maximum Cold. Remove product from the box. Attach the adapter kit. Locate your low pressure port. Place the end the adapter on the low pressure port and push down the block collar to lock it on. Press (hard) on the plunger to inject the solution. When all in and whilst still holding down the plunger, pull up the black collar to release the connection. Keep car running for a while or better still immediately take it for a run to spread the solution through the system. Job done. How simple was that? - not simple enough for some it would seem….

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.

I had my a/c system charged a year or two ago and the mechanic told me the system was completely empty but held vacuum, not so long ago my system was completely empty as i was getting no cold air at all only ambient. I've used ERRECOM uv dye and this along with a bottle of gas to recharge the system and a couple of weeks later it's still working just fine, I haven't been able to see any leaks with a UV torch and i'm hoping this product has solved the issue but only time will tell, I will update the review if it hasn't resolved my slow leak and if i find the source. You need some refrigerant in the system for the gas to circulate this product and a uv dye, so don't waste it on a empty system.

Top tips 1) Screw the syringe onto the adapter before fixing to the low pressure port. If you don’t you may lose the AC refrigerant gas already in the system 2) For those who say they can’t press the solution into the AC low side as it’s too hard….. get someone to sit in the drivers seat and raise the revs to around 2.5k rpm. As the revs are raised, press (hard) the syringe. If it’s still too hard to inject, then raise the revs. The higher the revs, the more it assists in inserting the fluid (think of higher revs as higher suction as the fluid is inserted) Hopefully this helps.

Good stuff seamed to do the job.

This is a great product and well worth the money. But Note: 1) It is ONLY for small leaks (i.e. if AC loses gas over a few months Rather than a few days) 2) You MUST connect it correctly, otherwise as others have said it will simply leak all over the place You must turn you car on, set the AC to lowest temp, then inject the solution. Injecting can be difficult because of the pressure in the AC system. So wear gloves and press the white connector down very firmly before sliding down the black locking loop. TIP: Inject a small amount and check for leaks, if no blue solution is seen, then depress plunger fully. Car must then be left to run for 30mins to allow solution to fully circulate in system.

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.

Didn't stop the leak

Buen producto.funciona bien

Heb het gebruikt in mijn citroën ds3 vanwege een lekke verdamper, waardoor het aircogas na zo'n drie weken weggelekt was. Dit product heeft voor mij helaas niet geholpen. Airco wordt niet meer koud. Kan zijn dat het met een kleiner lek wel zou werken.

Ottimo prodotto

Good
