Local stealer or from the usual board supporters (hint).
Dealers will most likely need to order the part but the board supporters (2002haus, La Jolla, Max to name a few) will most likely have the part ready to ship.
P/N 13521259269. Order 2 and keep one in your trunk along with your extra fuel filter, fuel hose……
I'm going from memory as I did this this last summer (in other words, 2x check your manual or McCarthy book).
If you're just replacing the belt them make sure you align the same.
If you belt broke, then make sure you align the crank first. Removing the radiator and fan gives more room to work. Remove the valve cover and manually turn the crank till #1 TDC aligns via the cam. Check the alignment at the crank. If the PO had removed the alt. pulley he/she may have misaligned. Remove the alt pulley and the plastic covers.
Then align the hash mark on the KF pulley and replace the belt. CD has a picture and hopefully he can post. Install the belt and replace everything is reverse order. While you’re at it, replace any belts and hoses you may suspect are past their prime.
Is the alt pulley or the toothed belt pulley all cruddy
if the toothed belt, are your covers intact? If not order replacements. If you car has/had an A/.C the lower cover is "modifed" (cut oujt) for the A/C belt and will let more dirt in. Don't over tighten during install as they will crack. Gently clean with a brass wire brush. When you remove the alt. pulley, note the orientation. If you don’t, you could misalign the alt. pulley when you re-install.
Good luck.
