Always get this slip if you can so you can check they put in the correct amount...some machines have outdated info and don't fill with the correct amount....as was the case once with my ALFA...too little. Although the machine does say how much its going to fill with before its starts.....ask what it says before they start so you can check on your phone that it's correct</div>

Degassed and all fine. They did not have a cap to cover the port so I searched the web for one. I zip tied a finger of a rubber glove over the port while I awaited the cap arriving the finger inflates showing the valve was not sealing. The valve is similar to the ones used on a push bike. New valve core fitted using a flit from EBay so no gas escapes then swapping the core. Car fine over a year on. Begs the question why fast fit garages insist on new valve core for road tyres but don’t change them on air can especially as the valves may not have moved since the cars production several years earlier. </div> <div class="bbCodeBlock-expandLink js-expandLink"><a role="button" tabindex="0">Click to expand...</a></div> </div> </blockquote>A god A/C mechanic will replace the mini Schrader valves during the service , they are cheap , and let's face it the one in the car are most likely to be as old as the car itself.</div>

<div class="bbWrapper">have you all seen the price of the DIY top up bottles at places like Halfrauds these days ! <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f631.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":eek:" title="Eek! :eek:" data-smilie="9"data-shortname=":eek:" />. Im sure the first one I bought some years back was about £25 , same bottle (R134a) is now £73 , R1234yf ? £100 !<br /> <br /> I still have an almost full bottle left and both A/C systems on my cars are spot on (famous last words) so hopefully all will be well this summer.<br /> <br /> I see they also sell A/C leak stopper . Anyone on here used it ?</div>

The sticker was corrected next model year.....the joys of driving Italian!!!</div>

If it's just intended to make old seals pliable again, I suppose it might work.</div>
 
<div class="bbWrapper">And if your car is a few years old, and you are going to get it regassed, it’s probably worth changing the drier canister too. Not a big expense, but dries out any moisture within the system.</div>
 
<div class="bbWrapper">Did a quick Google , mainly down to EU regulations and the fact that a 'litre' of R134a let out into the wild takes up to 12 years to Pi$$ off via natural absorption .<br /> <br /> R1234yf ? ....11 days.<br /> <br /> Fair enough.</div>
