How do I know if I need this Vanagon alternator adjustment bolt for my Waterboxer?

Most 1988-91 Vanagons with the Waterboxer engine came with this adjustable bolt and bracket. It's best to double-check your existing alternator setup. If your current bolt is damaged, missing, or you simply don't have an adjustment system, this replacement Bolt is likely what you need. If your van isn't equipped with this system, it's a straightforward and affordable upgrade.

Is this the correct alternator adjustment bolt for my 1983-91 Vanagon Waterboxer?

Yes, this specific alternator adjustment bolt is designed to fit Vanagon models from 1983 to 1991 equipped with the Waterboxer engine. It's a direct replacement for damaged or missing bolts, and also serves as an easy upgrade if your van didn't originally have this adjustment system.

What if my Vanagon doesn't have the alternator adjustment system at all? Can I still install this bolt?

Absolutely! If your Vanagon Waterboxer (1983-91) is missing the original alternator adjustment system, this bolt and the optional Tensioner Bundle provide a simple and cost-effective way to add it. The installation requires only basic hand tools, making it a manageable DIY project.

Is there a way to get both the bolt and the bracket? I might need the whole assembly.

Yes, you can purchase the Alternator Tensioner Bundle! This option includes both the replacement alternator adjustment bolt and the necessary bracket, often at a better price than buying them separately. It's a great choice if you suspect you need more than just the bolt.
