Calais V6-3300 3.3L MFI VIN N (1990)
Figure 4
By visually aligning the front edge of belt spans No. 1 and No. 2 so that the edges align perfectly, compare them with span No. 3 (See Figure 2). If the
belt on the crank pulley is forward of spans No. 1 and No. 2, then the A/C compressor needs to be shimmed forward (See Figure 3). If belt span No. 3 is
not forward (belt span No. 3 cannot be seen), then align spans No. 1 and No. 2 along the rear edge and then compare them wfth belt span No. 3 (see
Figure 2). If belt span No. 3 is rearward of the edges of spans No. 1 and No. 2, then the crankshaft pulley must be shimmed forward (see Figure 4.)
If the A/C compressor requires shimming, loosen the three compressor attaching bolts and install a .030" front end alignment shim (Part No. 6270717)
between the bracket and compressor at all three locations as shown. It will be necessary to use longer bolts of the same hardness for the two front
attaching bolts (Part No. 11507023). Tighten the two front attaching bolts to 40-60 N-m (30-44 lb.ft.) and the rear attaching bolt to 20-34 N-m (15-25
lb.ft.). In some cases, it may be necessary to use two shims (.060"); however, never shim more than .060".

pulley. Reinstall the pulley and tighten bolt to 270 N-m (200 lb.ft.) In some cases, it may be necessary to use two shims (.060"); however, never shim
more than .060".
