We have a 1996 Voyager and the air conditioner locked down. Is there a way to bypass the airconditioner with the drive belt that controls all the mechanics under the hood? The motor was making a very loud rattling noise before the ac unit locked down. What can we do other than replace the air condtioner and compressor?

Without seeing the belt diagram or your motor, if not sure about the routing. Make a sketch with arrows of the pully direction of rotation. See if there is a direct straight line between the pulleys that are adjacent to the pump your bypassing and will still accomodate the direction of those pulleys. If it is good, take a string and wrap it around the pulleys and bypass the compressor. Now measure the string and record it. count the grooves and record it. Tell the counterman at the parts store your marked down numbers and ask for that size belt, the next size up and the next size down. Return the belts that didn't work.

Suggested Repair

Identify the engine size. A 3.3 may accept a bypass pulley and bracket in place of the AC compressor; check the belt diagram on the passenger-side strut tower. If routing a bypass belt, confirm adjacent pulley rotation directions, measure the path with string, count the grooves, and try that belt length plus one size up and down.

Conversation Summary

The owner of a 1996 Plymouth Voyager wants to bypass a locked AC compressor with the serpentine belt after the compressor rattled and seized. One reply says a 3.3 may have a bypass pulley and bracket, and the underhood diagram may show the routing. The expert recommends verifying pulley directions, measuring the bypass path, and trying nearby belt lengths.
