Fits perfectly on my 90 6.2 1 ton. Old one was overcharging and draining battery. This one is performing flawlessly.

This Carquest Premium Remanufactured Alternator replaced and old rebuilt alternator that lasted over 20 years. This new alternator looks like brand new and in combination with a new DieHard battery has improved the electrical performance of my 305CI 76 Chev Nova. All the lights are brighter now with the new alt/bat the engine starts much easier. It's nice to have a fully charged battery again. I waited a few months before writing this review to help determine if the new alternator was going to last. It's been my experience that electronics will fail fairly quickly if it's going to fail. I'm happy to say that the alternator seems to be perfect. The wiring and belt configuration were identical to the old and installation was easy and fully explained by installation instructions that were included with the unit. Thank you Advance Auto Parts.

well this is for a 1984 Chevrolet V8 305 H engine 78Amp . I had the OEM alternator creating high volts. so I did purchase the carquest refurbished alternator. the carquest alternator worked great charged and put out 14.5volts DC .. then when I put the headlights , on the alternator failed . could not output the power to hold the volts dropped down to 12 volts. I was very frustrated that now I have the opposite issue , low power .. the OEM original high power. so I returned it to the store they did take it back and no problem .. did not have one in stock , so I went back home and took apart my 1984 alternator .. what I found was the power diodes had some corrosion on the diode fingers .. cleaned up the copper and the alternator worked perfectly . not a common problem but if you have some ac volts on the brown #1 alternator wire I had 4volts AC , then those diodes are the problem .. must not have ac volts on that #1 wire or this is how it will react .. bench testing is not 100% accurate !!!

alternator was the correct part. had to change over the pulley. my pulley 3inches this 2.625 in.. started engine , alternator had a delay in charging but I reved it up and it worked great.. I had a high voltage problem on my oem alternator and some ac volts causing the choke relay to flash on.. so I thought it was fixed until I put the headlights on... well the alternator volts dropped down to 12 volts.. headlights off volts up to 14.5 volts. I then measured the amps , the alternator put out only 18 amps with the headlights on and 12 volts was all it outputted.. none in stock and when I picked it up looked like a returned alternator.. but the store had one so I gave it a shot.

Good price, and had it in stock. I needed to modify the alternator to make it fit my1978 Jeep, probably something the average backyard DIYer wouldn't do. Been working well for about one month, and I expect it to continue without a problem.

The part is probably fine, but it's the incorrect one for the vehicle I selected. I wanted one for a 1977 Cadillac Deville, but the recommended "exact fit" part is incorrect. Change your vehicle to a 1977 Seville and you'll get the correct one; word to the wise.

Works good, easy install on my 79 Chevy. The fan on this alternator is a little bigger than oem which made it hit my power steering pump bracket when i had it fully tight on the belt, loosened it a tiny bit and the clearance was fine.

Purchased to replace a failing alternator. First replacement did not charge at all. They traded me a second unit. To my surprise, it charged for a few seconds and also failed. Two faulty reman units out of the box is enough for me to move on to a better product. Likely from a better supplier. Advance should not be selling this garbage.

The product came without an insulator on the positive post it's just tightened right down on the casing. And then once I noticed I took my cable off the positive post and the whole post came off in my hand and I can hear what I think is the nut backing for the post rattling around inside. ALSO it grinded as took as I took it out of the box which I promptly figured out was a magnet because I saw pieces of it falling out of the air vents. Absolutely would not recommend just don't buy it.. I will never use a carquest product again this is absolutely ridiculous.

I have a 1984 Chevrolet Monte Carlo and the Alternator on the car was original equipment. Anyway my battery was being drained out every night and car would not start the next morning. I didn't receive a check engine light but I suspected the alternator was going bad. I replaced the alternator with this one and placed a charge on my battery. So far the replacement alternator has worked perfectly and I couldn't be happier. I recommend this alternator for anyone who needs one at a great price and built with quality.

I ended up returning the first alternator. After just two weeks the alternator began to have an internal squeak. I though it was the belt, but when I took off the belt and turned the alternator by hand there was a high pitch squeak. The amps and volts where all good. Something just wasn't lubricated. The second alternator has been on for a few days now. It seems to be working properly and quietly.
