10 minute job - Alternators

This is very easy to install with 15mm bolts and I think 8mm at the back with a small one Wire. Mine required some curiosity to get and some. I like to put in a new one 🤣. However super easy to get in and out of.

Pros
  • GM Recommended part for your GM vehicle's original factory component
Cons
  • Contact Seller

Excellent for alternators

Works great. The alternator turned out to be all new components. I believe it may have been a remanufactured block based on the markings resembling those used to properly assemble the parts. Another buyer wrote a similar review, which caught my eye. Another clue was the box it was packaged in.

Pros
  • Components are tested to original specification and have exceptional durability.
Cons
  • Unfashionable

False advertising of Starters and Alternators

Claimed Description: 100% new manufacture exact replacement of your GM car's original alternator What we received was RECONDITIONED! Generator. Very misleading and uncharacteristic of Revain. I'm embarrassed that I didn't read previous reviews that said the same problem from other misled buyers. I expect Revain to take a closer look at the products they sell.

Pros
  • Offering GM Quality, Reliability and Durability OE
Cons
  • Negative Impression
