Refrigerant Leaks on 2003 Ford Explorer

Where and what size O-Rings are needed to replace and seal the A/C system. And what is the refrigerant charge?

Asked by for the 2003 Ford Explorer
The different components in your A/C system use different size o-rings. Check with your local parts store or Ford dealer parts department for o-ring part numbers & prices and the A/C charge amount. (There may be a sticker under the hood stating the charge amount.)
