Need to find a diagram or layout of the belt system in a a Ford Econoline 1987 E-350 7.5l Motorhome/RV

Just go to an auto parts store/distributor and tell them you want a fan/alternator belt for a 1989 Econoline with a 460 engine. That's all you have to say. Speak nothing of Motorhome, it really screws them up when you say that. All the have to know is that it's an Econoline 350 with the 460 engine. I have 2, an 87 and 88 Tioga with 460 engines and I never mention the word motorhome. I'm scrapping the 87 and have all kinds of stuff to sell from it. A complete front end with fenders, hood, doors windshield and bumper in good shape. I'm putting the seats and refrigerator in my 1975 18 foot Midas on a Dodge chassis, now with a small block Chevy 383 and 700R4 trans in it. Already put all the cabinets and booth from the 87 30 foot Tioga into this little 18 footer. Oh, the front end fits from 83 to 91.

Typically if the batteries are in the engine compartment they are for the engine. There are usually a bank of remote batteries located in an access panel in the R/V body.

It is possible you need a fuel pump or carb could be all gumed up from sitting around

Is this an F350? Heading say's f53. What size engine is in this vehicle?
