Porsche 911 Alternator & Fan Pulley Tool – 99957104702

If you’ve ever tried to change an alternator belt on an air-cooled 911 without the correct tool… you’ll know exactly why this exists.

This tool is designed to safely and correctly loosen and tighten the fan pulley nut, allowing you to remove and refit the alternator belt without damaging components or resorting to guesswork.

It’s one of those tools most owners don’t think about — until they actually need it.

And when that moment comes, nothing else really does the job properly.

Whether you’re carrying out routine maintenance or dealing with a snapped belt at the side of the road, this is the tool that makes the difference between getting moving again… or being stuck.

Why it matters:
✔ Correct engagement with the pulley nut
✔ Prevents damage to fan and pulley components
✔ Essential for proper belt tension adjustment
✔ Compact enough to keep in your toolkit

Perfect for:

• Porsche 911 F & G Series (air-cooled models)
• DIY maintenance
• Roadside emergency use
