I ended up returned this because the pulley was the wrong size - Lexus changed these mid-year on the 99's and mine was built in the transition month so it was hard to find the right answer. I needed the second production with the 57MM pulley - this is measured where the belt rides not the outer pulley diameter. Easy return and great service from Advance.

Was same size and fit like the previous one. The only difference was it does not have a hole that the original has where the wire clip attaches to; which did not matter because the wire is still pressed tight against it.

I purchased & installed this alternator on April 13, 2017 and it's now June 25, 2017 a mere 2 months later and, I'm uninstalling it and exchanging it for another as it has failed!!! I hope the new one last A LOT more then 2 months!!! For clarity it was tested and confirmed in car at Advance Auto to be a bunk alternator, only putting out 12.5 volts under load!!!

Bearings are validated to OE standards and loaded with premium OE-standard lubricants. New or remanufactured, a DENSO alternator is a quality component.

29 performance and safety checks.
