* No factory mounting points: There are no pre-existing brackets or mounting locations on the passenger side for an alternator. You'd need to fabricate custom brackets and potentially modify the engine block or accessory drive housing. This is a challenging task requiring welding, machining skills, and a good understanding of engine mechanics.
* Belt Routing Complexity: Routing a serpentine belt across the engine from a passenger-side alternator to the other accessories (power steering pump, water pump, etc.) would be extremely difficult, if not impossible, without significant modification and potentially custom pulleys. A 6-groove belt adds to the challenge.
* Clearance Issues: The passenger side often has limited space due to the exhaust manifold, steering components, and other accessories. Finding enough clearance for the alternator and its belt may prove impossible without extensive modification.
* Electrical Connections: Relocating the alternator also means rerouting the wiring harness. This involves understanding the wiring diagram and ensuring proper connections to avoid electrical issues.
Instead of moving the alternator, consider these alternatives if you have a specific reason for wanting it on the passenger side (like a custom engine bay setup):
* Use a different engine: If this is for a custom project, consider an engine that naturally has the alternator on the passenger side.
* Seek professional help: A custom fabrication shop specializing in automotive engine builds could potentially handle this modification, but it would be a significant and expensive undertaking.
In short, installing an alternator on the passenger side of a 1989 Chevy 4.3L V6 is a highly complex and impractical project. Sticking with the driver's side location, which is the original design, is by far the easiest and safest solution. If you need a 6-groove serpentine belt, simply find the correct belt for the standard driver-side alternator setup.
