So i just about have my 86 305 4bbl with A/C, E fan, and P/s back together. The only thing left is putting back the v belts, but i cannot figure out how the hell they route. Two belts broke on removal before the tear-down of the engine because of dry rot, so i have no idea where everything goes now. So far i have the serpentine and air pump belts on. Air pump is going from the crank to the air pump, and the serpentine is going from the crank, then water pump, then alternator. I have no idea how the rest go.

I couldn't find anything under the hood as far as a routing diagram, and i couldn't find anything online or in the manuals i have either. I was looking at replacement belts online and there are like 6 different belts for this car.

Currently the P/S and A/C aren't connected to anything. If anyone can tell me the routing of the two missing belts as well as the part numbers or something it would be greatly appreciated.

 

If you have a serpentine set up it is one belt with a tensioner. So, I'm confused what you have. If you have V belt set up you hadn't mentioned A/C or power steering.

 

the alternator has a serpentine belt and the rest are v belts. There is no tensioner. The car has power steering and a/c.

 

Its still a Vbelt set up. You will have the alternator turning off the crank pulley to the water pump. You will have an Air pump vbelt off the crank pulley. You will have a power steering pump belt from crank and water pump pulley to power steering pump. Lastly you will have the AC belt. They are the only belt driven accessories on the motor. Belt routing is not hard, unless the brackets have not been properly replaced....then its a PITA

 

a/c belt goes around water pump to a/c comp, the p/s pump back to crank. p/s either goes around crank, but dont remember if it does or doesnt go over water pump
