Which amperage should I choose, 140 A or 150 A?

Match the rating of the alternator you are removing. Choose 150 A if your car has heavy electrical loads or you have added accessories such as amplifiers or auxiliary lighting.

Will this fit my Saab 93?

Fitment depends on engine, model year and the original alternator's connector and mounting. Check the part number and amperage against your current unit before ordering.

What is the core deposit?

It is a refundable charge held until you send back your old alternator. Return the core in the supplied packaging to get the deposit back.

Is this new or remanufactured?

Units like this are typically remanufactured, meaning the housing is reused with new internals. Ask the seller to confirm the condition before buying.

Do I need to replace the belt at the same time?

It is worth inspecting the serpentine belt and tensioner while the alternator is off. A worn belt can slip and cause charging problems that look like alternator failure.
