There is a routing diagram under the hood on a placard.
If you don't have this card you can go to any Autozone and they should be able to print one for you
It should be on a sticker on the radiator fan shroud. If it's worn away, look at a friends, or in the junk yard.
What do you want the "diagram" to show you? Mechanical assembly? Hydraulic fluid circuit? Serpentine belt routing? Be specific and include the vehicle year. Sorry, I cant be more helpful without more info.
belt diagram for ford 4.9 without ac.
Yes, I need a diagram of the serpentine belt for a 1997 3.8 liter Bonneville SE without a turbo charger.
Might have better luck in a Chevy forum. http://experts.about.com/q/Chevrolet-Repair-808/indexExp_33416.htm
If your local auto parts store has a listing for the belt without air conditioning, then yes it is. They should also be able to provide you with a diagram of the new routing.
If that model was available without a/c, you will need to purchase the belt for a 95 town car w/out ac, and follow the appropriate belt routing diagram for that model.
under the hood.
There is an idler/tensioning pulley that keeps the belt tight. You must release the tension on it (usually they have a nut on the shaft that can be used for leverage to release the tension). Then remove the belt paying careful attention to how it is routed. There also should be a sticker under the hood that shows the belt routing. Usually it shows the routing with different options- cars with A/C have a compressor that ones without do not have. Just follow the routing diagram to install replacement belt.
You should be able to. Go to your local parts store and give them your make and model. Tell them you want a serpentine belt for your engine model without A/C. There should be a belt routing diagram under your hood that will show you how to install.
Under the hood should be a diagram of the belt, this is your best reference without the service manual. All you have to determine is which direction to rotate the belt tensioner, then put the belt back on as shown in the diagram.
There is no spring loaded tensioners on the Mercury Villager. Look for manual adjustments, loosen the nut in the center of the adjustment idler's and then move the adjustment bolts toosen the belts for replacement. Since this vehicle does not have just one long serpentine belt the routing is fairly simple to figure out. If the belts are still on the vehicle you can draw a quick sketch of the routing to help when re-installing the belts.
