Alternator (90A) [Watercooled Vanagon]

This is a brand new alternator/regulator assembly. No core charge: nothing for you to return! We worked closely with the manufacturer to produce this very high-quality alternator to replace the original Bosch unit for which there have been no new replacements for many decades. We have verified that this alternator fits and performs as it should.

Pro tips:

The #1 thing that ruins an otherwise good alternator is a bad starting battery. When replacing an alternator, it is imperative that your starting battery has been verified to be in proper working order (fluid and load checked, and not too old; replace if in doubt) and is fully charged. Always check that the charging voltage is within specifications (per the Bentley repair manual) after replacing an alternator. Following these steps will place your charging and starting issues squarely in your rear-view mirror!

Additionally, replacing your alternator presents a great opportunity to upgrade your entire alternator system with our Heavy-Duty Alternator Bracket Kit, Alternator Tension Bundle, Wiring Harness Upgrade, and Alternator Charge Initiation Kit. And of course, always toss on a new V-belt and carry the old one for a spare!
