Bought and had issues right away mailed back and got replacement, lasted 3 years then seized up, not even 25000 miles on the alternator.
Don't Waste You're Money
(Maryland) | February 3rd, 2018
Purchased 1/2015 as an upgrade to the stock alternator. It lasted 3 years and less than 15,000 miles. The problems began a few months ago with the truck being incredibly hard to start & sometimes stalling at start-up. Once it got running, the truck seemed a little sluggish. One morning went to start the truck & the truck wouldn't start, almost thought the batteries were weak & I would need a jump. I did finally get it to start, but only after ripping the serpentine belt apart, only to find this $400 alternator was seized, bearings must be junk. I almost want to give this product 2 stars for being able to stall a 7.3L....kinda impressive!
Failed After 1 Week
(Longmont, CO) | February 25th, 2015
I saw great reviews for the Mean Green alternators for my 02 F250 7.3L diesel. Two days after installation there was a bad electrical smell. Figured it was just varnish on the coils. Smell never went away and coils are now crusty black. Several attempts to get a return call from manufacturer have failed! Warranty may claim to be several years and 300 miles, but good luck when you need to return it!
