Here's a breakdown of what contributes to the work involved:
* Accessibility: The alternator's location on a 1998 Malibu might require some maneuvering to access it. You'll likely need to remove some components to get a clear working space. This could include things like belts, brackets, and possibly even the power steering pump (though not always necessary).
* Bolts and Fasteners: Expect to encounter several bolts and possibly some stubborn fasteners that might require penetrating oil and some muscle to loosen. Rust and corrosion are common on older vehicles, making this aspect more time-consuming.
* Electrical Connections: Disconnecting and reconnecting the alternator's wiring harness requires care to avoid damaging the connections or accidentally shorting something out. It's essential to label wires before disconnecting them.
* Belt Tensioner: You'll almost certainly need to deal with the belt tensioner to remove and replace the serpentine belt before accessing the alternator. This can be tricky if the tensioner is stiff or seized.
Time Estimate: A skilled mechanic might complete the job in 1-2 hours. A novice could easily spend 3-5 hours or more, especially if they encounter unexpected problems.
Tools Required: Beyond basic hand tools, you'll likely need:
* Ratchet and socket set
* Wrenches (various sizes)
* Screwdrivers (Phillips and flathead)
* Penetrating oil
* Jack and jack stands (essential for safety)
* Possibly a serpentine belt tensioner tool
In summary, it's not an impossibly difficult job, but it does require patience, the right tools, and some mechanical skill. If you're unsure about tackling this yourself, it's always best to consult a qualified mechanic. The cost of labor at a shop will likely outweigh the cost of a new alternator, so weigh the time investment and potential frustration against the cost of professional service.
