Question about Mercury Sable
There is no problem with reinstalling the Serpetine Belt. But what have you done about the pulley that is locked up?
You need to find the bad pulley or you will smoke a belt before you leave the driveway. Unplug the wire on the A/C clutch pulley if the compressor is locked up. You need to do this because the A/C will cycle when the dash is set to Defrost setting as well as on AIR.
The idler pulley is the spring loaded tensioner. It is common to lock up. If this pulley is bad, you can keep using the A/C and just replace the Idler pulley.
Check the Alternator, water pump, anything that turns to find the lockup. The timing is done inside the engine with a steel timing chain and is not a part of the Serpetine belt.
