I need some serious help. I was given a 2008 town and country and have been getting A TON of work done on it and a mechanic went MIA and left me with a bucket of bolts to put my whole belt system back together like the water pump alternator etc that whole side of the engine is currently in the floor board with all parts and bolts (hopefully) but i need some serious guidance on what BOLTS go where. I have plenty belt diagrams but not any for the bolts??? Please help me.

 

The diagrams from online parts sites can be of some help, they usually show where the hardware goes and what size it is:

Here are some links for the 3.3L/3.8L engines (you didn't specify which engine you have but these are the most common):

Pulleys and Related Parts

Hello what I do is take for instance the timing cover, I place the questionable bolts in the holes where they fit and look to see how far the bolts are proceeding out of the other side. Normally they will stick out about 3/4" Also you can try the threading the bolts into the suspected holes. Hope this helps.
