Replacing the alternator belt on a ’94 Honda Passport is a fairly routine task. It only requires the use of two tools to accomplish it. One of these would be a socket wrench and the other a pry bar. When attempting to replace the belt it is imperative that you replace the old one with an exact match. Alternators vary in size from manufacturer to manufacturer and for the size of vehicle they are for: small, midsize and sedan. Honda, however, keeps up with its suppliers and any auto part store should be able to provide you with an appropriate belt.
As for the alternator belt itself, it is what distributes the torque produced by the engine to the alternator. The alternator is the mechanism that produces the electrical current necessary to run the car. Belts should be inspected and replaced regularly, especially if they are showing signs of wear (You should check these every 75,000 miles or so.) A worn belt will have tears, rips, and cracks or even be loose. A loose belt will greatly impede the electrical output of the alternator and the automobile will cease to function properly.
Remember that all the belting systems in a vehicle are interconnected. This means you will need to remove some of the others to get to the one you are changing. It helps to make notations of what goes where so you can replace them properly. Okay, now locate the power steering pump. The tensioner bolt is located on the bottom of most of these. You will want to get the right sized wrench to loosen this bolt enough to remove that belt.
Then you move over to the AC compressor and do the same loosen and remove procedure. You now have access to the alternator belt. On the alternator there is an adjustment bolt you will want to loosen this bolt and pull the belt off completely. The alternator will be loose from the mount. Put on the new belt making certain that it is around all the pulleys. Carefully, use the pry bar to force the alternator back into its proper position and tighten he bolt. Keep tightening until the proper tension is restored in the alternator belt. Now replace all the belts you removed, working in reverse order from the notations you made. If you have any parts left then you have not been successful.
