Here's why:
* Vehicle Specific: The presence of a gasket washer depends on the specific model year, engine size, and other factors.
* No Access to Vehicle Data: I am an AI, and I do not have access to your vehicle's repair manuals or specifications.
Here's what I recommend you do:
1. Consult Your Repair Manual: Check your vehicle's owner's manual or a repair manual for your specific model year.
2. Check Online Resources: Search online for repair guides specific to your 1999 Pajero Sport alternator.
3. Consult a Mechanic: The best option is to consult a qualified mechanic. They will be able to inspect your vehicle and confirm whether or not a gasket washer is present.
Remember: Working on your vehicle's electrical system can be dangerous. If you're unsure about anything, it's always best to seek professional help.
