AC valve replacement?

I've found my GTVs AC leak. The filling valve leaks. Is there any way to repair or replace these valves?

Thanks

Andy

If it's only the valve, you're in luck, just a few quid, they can do that when you get the system serviced.

If your A/C system has been open to atmosphere for a while, though, you will really need to replace the receiver/dryer.

This is filled with a dessicant to remove any moisture from the refrigerant. Once the atmosphere has got to it, however, it will need replacing, adds another £40-60 to your bill...

Fair enough, It is going back to Kwik Fit who filled it last time tomorrow, they said they will try and refit the valve thingy. Is this a hard job? Do the AC valve use the same inserts that I used to use to re-core shraeder bike tyre valves?

Wouldn't have thought it was too difficult! But I think they are different from the bicycle ones...
