Question about 1995 Mercury Sable
My mechanic has installed 2 serpentine belts. The first belt he had to replace as he states that the pulley on the water pump was broken and cut the belt. I now have a new alternator and a new water pump and a brand new 1 year warranty serpentine belt. Last night after test driving the car for 2 hours I went to pick my son up from work and the brand new serpentine belt fell off for the second night in a row... Are their any diagrams that he can look at as he is obviously not installing the belt correctly if it keeps falling off.
I have the same car and last night my belt slipped off. The top small pulley backed it's self out. The problem is in most cars the pulleys are reverse threaded so this wont happen, in ours not so much. The pully spins loose with the turn of the belt so it has to be tightened way down. IT's a pain. Here is a diagram I found and You need a 15mm wrench, which doesn't just come in most sets. Good Luck
The book says "Using a 15 mm socket or wrench on bolt attaching drive belt tensioner pulley, rotate drive belt tensioner clockwise. Make sure spring keeper engages into slot." I would put a socket on the 15 mm pulley bolt and a long handle for leverage. Thats one tight spring.

I think you have the same problem I had, but my car was a Honda. Remove the large nut that keeps the harmonic balancer pulley on and i bet you will see that the bolt behind it is semi worn off due to wear and tear. It may appear to be fine but look closely. If it is worn the pulley will loosen up eventually and then your belt will keep coming off. Replace the bolt and you'll be fine, but you may have a problem getting it out, if so you may want a mechanic to do this, i didn't want to tackle that project so i let someone else do it, but i did manage to get the large nut off myself that holds the pulley in place. i replaced the pulley knowing that the bolt was worn down and sure enough the belt came off again after driving a liitle while. I checked the pully again and it was loose.
(Tip)-I had to remove plastic engine coverings under the car and turn the front wheels in order to get the pulley off.
