1985 B250 318 belt routing
Thanks the diagrams helped, mine is actually different again from those but it was enough to figure it out. A few tips I coded all of the bolts with dots and did the same on the locations. The waterpump has 3 different lengths of bolts and the entire front adjusting bracket and spacer system is quite convoluted. Here are some pics of the belts. Maybe it will help someone.
318/AC/60ampalt/airpump/ps/ and idlerpulley 4 belts.
The old girl now has new w/p,belts,hoses,fuel filter,fuel pump,plugs,wires,cap and rotor,radiator and reconditioned heater core.
Now time for oil change,trans filter,diff fluid and check brakes.
None of this stuff had failed but it is our camper van and hasn't been used much at all since 2003.
