I have a question regarding recharging of the A/C system. The haynes manual shows in chapter 3, figure 12.21, that the system can be charged on the low side with an off the shelf kit. I also have a Bentley's manual that states that only the high side can be charged with a special machine. Who should I trust?

Hi duke,

Well, both sources are correct, if you rearrange your wording a little. The system can be charged on the high side, but only with a professional-grade recharging machine. This machine charges through the high side, with the engine not running.

The way the Haynes manual describes the charging procedure is with a consumer grade charging kit, through the low side, with the engine running. NEVER try to hook up a charging hose and a can of refrigerant to the high side and charge the system with the engine running - the can of refrigerant could explode! That's why the high side fitting is different.

Hope this helps.
