installing new AC belt
OK. So I removed the front pulley along with the 3 shim rings, placed a new belt around the compressor pulley, and replaced the front crank pulley over the new belt with the 3 spacer rings still in front of the pulley (not being used). I think I followed the shop manual instructions correctly:
1. Tightened the bolts by hand,
2. Turned the compressor pulley to free up the belt,
3. Repeat steps 1. and 2. until front pulley is seated and belt moves 10mm-15mm when pressed.
Maybe because the belt was new, I could not get the pulley to seat, so I removed everything, put one shim ring underneath the front crank pulley and put it all back together again (using the same shop manual technique). Once again the front half of the would not seat down tight against the rear pulley half, but this time the AC belt was looser (I could push it down about 10mm).
I took the whole thing apart again and this time tried it with 2 shim rings under the front pulley half. Again I could not get it to cinch up tight to the rear crank pulley half (even though I spun the compressor pulley as much as I could, and the belt would no longer slide loose in the crank pulley).
Finally I put all 3 shim rings under the front pulley and tightened bolts by hand, spun belt free, tightened bolts by hand, spun belt free, repeated many times, still could not get front half of pulley to pull all the way down on the 3 shims without pinching the belt between the 2 pulley halves. And the belt seemed pretty loose (I could push it down about 25mm).
Is this the way it should be? Do I need to re-install everything (fan, radiator, coolant, etc) and crank the motor over with the starter to see if the belt frees up and then tighten the pulley bolts again (and keep turning over the engine and tightening the pulley bolts until they seat fully)?
Can I just crank the engine a little bit without re-installing fan and radiator and coolant? How the heck can you tighten the pulley bolts when the fan, radiator and shroud are installed? It seems virtually impossible to turn the crank otherwise unless I put the car in gear and push it.
