So far everything is going well!
I’ve had this alternator in my truck for about a week or so now and it’s been working just great. Alternators are the sort of things that tend to be good up until they have a failure, so I can’t quite speak to the longevity of the part, but the castings and such all seemed really good. Oh, a note for people installing these in GMC vehicles after 2007. Measuring the voltage at first threw me because it was putting out 15v. I found out that the ECM in GM vehicles has some smart battery charging and that it will charge at 15v depending on certain conditions, such as your battery being really low voltage and also when it is very cold out. It’s the winter when I write this review. This is to compensate for the charging characteristics of lead acid batteries and, at the temperature the vehicle was at when I measured, this voltage was the correct charge voltage.So yes, everything seems good and my truck is charging like it should. The voltage is nice and stable and measuring with an oscilloscope showed a smooth waveform. I hope it lasts, but since I did the swap myself I have the original alternator and plan to rebuild it to have on hand. (You can buy kit’s for fairly cheap, though I bought the new alt because I wasn’t sure if it was diode failure or regulator failure on my old alt.)

Faulty Alternator
It failed to charge properly and showed issues within a short period. Installation was straightforward, but it didn’t perform reliably.

Good part
Right fit, works well, new as ordered, minor squeak before break in or I’d give it a five

The auto parts store is not always right
Was told at the auto parts store I needed a new alternator turns out I bought this product for nothing it was the starter all along but works great 👍🏽

Really good price .
This works really good just like the OEM .

Good product, the fit was a little tight, I had to persuade it a little. Works fine, produces 14.3 volts and runs quiet.Good price. I just installed this, I will update in six months.

Very bad product, connector was broken and the placement of the connector itself was off making it difficult to access,it makes whining noise that can be cleared heard by anyone standing next to the car, whining noise is also audible in the cabin when the car is idling. No issues with the charging but the noise puts me off, I will not buy again I value my car. Not recommended.

Très bien

Good replacement alternator at reasonable price. Would recommend as it does the job as good as an OEM.
