View Full Version : Engine Vibration after A/C Install

Well, we now have cold air in our '66 but now I have a pretty noticeable engine vibration when I turn the A/C on.

No vibration at idle with A/C full blast or when A/C is off.

Anyone experience this issue??

First and easiest thing to do would be to remove the belt to the AC compressor and inspect it for lumps or buldges. Run engine to see if the vibration is eliminated, if so, something in the compressor is the culprit or causing vibration from being out of balance.
