Ok this will sound strange but I have used one of my wifes nylons in a pinch to get home. ;DJust stretch It around the pulleys and tie a knot. No tools and takes about one min. works great and will keep the lights on and the car from over heating.
that is fantastic. Just to clarify . . . do you use just one leg section? i am assuming you cut off the panty section .. . or do you leave the panty section? Wouldn't it be flapping about? Maybe I'm overthinking this, but if I'm going to ask my wife to contribute this particular garment "to fix the car" it better work.

Some wise-ass German engineer designed the worse possible way to route and tighten/loosen that alt belt.
1st disconect the neg batt lead
2nd remove the top bolt on the alt to alt bracket
3rd loosen the bottom alt support bolt below the IP
4th loosen the nut on the idler pulley
5th loosen the idler adjustment bolt
6th find something to bang like hell on the idler nut in the forward direction to get the f'ing pulley to move fowards enough to get the new belt on
7th tighen belt and all associated hardware.
Let me know if you need me to walk you through an oil change
Hello, I did not read the above stuff because it looks like there is an argument going on.
I have driven these stinking slow cars since 1981.
I have learned to always carry a spare alternator in each of the cars I own either behind the passenger side seat or in the trunk (in a Jetta). I also carry two metal ammo cans wth a full complement of "our" numerically uneven (13 mm, 15 mm, 17 mm, etc) wrenches and sockets along with screw drivers wire cutters and some spare wire. I always have at least one spare belt of each type specific to the car within the car. I also carry at least one good voltage regulator with new, long brushes on it along with fuses some screws, vise grips, jumper cables, and a 12 volt tire pump. I carry one complete alternator idler pulley (Mk. II with air conditioner) and its corresponding hardware. Oh, I almost forgot a new pump shut off solenoid and curved 15/16 Snap on wrench for it.
I carry two original VW jacks which are in good shape....because they are amazingly light and they do work in a pinch.
I always have two Sears rechargeable LED trouble lights which are really usable for everything from emergency car repairs to avoiding rattlesnake bites at night......got one yesterday....the SNAKE, NOT the bite.
Why do I go to all this much hassle??? Because I live out here in the sticklers and drive in all types of weather in very high mileage cars.
Over the years, I have had to use ALL of this stuff. The worst was an air conditioned Mk. I alternator in the middle of the night in the middle of winter in this hell-hole they call Wyoming!!!!!
What was your question again......?
EDIT: A water pump? Ah, NO, I do not carry one of those.....but, I do reach in a give it the wiggle test all the time

The steps above is the easy part and can be done from above. What has been omitted is the power steering belt and the water pump/AC belt, which has to come out first before the alternator belt can go on, and which can only be done from below the car by loosening the pwr steering tensioner and the pulley. Then the water pump /AC belt has to come off next, which means loosening the tensioner on the AC compressor and fighting to get the belt off. I just can't imagine removing and replacing those three belts in an emergency on the side of the road unless I have practiced it and kept all the tools used in the practice in the car.
