05+ Alternator Failures

[firestang70]

If I remember correctly Ford wants $330.00 + a $75.00 core charge for the remanufactured altermator. Hawgman found this place on ebay that sells them for $129.95

Is this the latest part number or the earlier style? Thanks

I've got 42k miles on my PA Performance 200A alternator with no problems either

Mines an 08 from Feb with over 24k on it so far an no issues. Is this something that happens all of a sudden or are there warning signs?

Usually just a CEL with a P0340 DTC.

80k on my original, KOW.

Mine failed after I put in my KB. Somehow it started to melt. I got the remanufactored one and it has yet to fail.

80k on my original, KOW.

Holy shit!!

At my failure rate I would have gone through 8 in that many miles. But at an average of 5,000 miles per year that would take 16 years.

I firmly believe that these alternators last longer with a better battery. 90% of alternator failures are due to having a weak battery. After my first alternator died I replaced the battery with an Optima yellow top and have gone 48K with no problems. I'm replacing that Optima with a Braille 21 pounder 550 CCA to lose 22 pounds of weight. We'll see how long the alternator lasts with this battery.

73k miles on my `05 with the stocker.

My '06 has 33k on the original

My second factory alternator died with the optima. You're just lucky

The one on the 05 went out ~ 60k...

(An old timer here using the search feature to find the OLD part number)....which I found here: http://www.s197forum.com/forum/showpost.php?p=286062&postcount=13

I paid $309 wholesale from Ford and now the fuckin thing is going out! I gotta get out there and find the number on it, but I bet it ain't a 7R3Z-10346-B!

87K...you should feel lucky. Get a PA Performance and be worry free.

 

[Tre06GTP1SC]

Do you have a link to the PA performance one? My 06 has 36K and still on the original alternator

Part # 2158W (130AMP) or # 2158WHO (200AMP). You can also have it powder coated for around $40.

hmmm fwiw they warranty replaced my alternator trying to chase a belt squeak. That did not fix the problem, but then within 2 weeks the REMAN alternator they gave me...its bearings died. Then another ford dealer wouldnt warranty it because it was on a dealer installed FRPP supercharged car so "that voids my warranty." Yea whatever asshole...took it to my friends at Downs ford in toms river. No problems. Changed it right out. All american in paramus....you have fun being everything thats wrong with the car business.

My 07 was built in Sept 06. Original alternator died in less than a year at about 9K miles. Covered under warranty. Now, with 25K on the odometer, my alternator is starting to make the same noise the original one made just before it puked, so I'm likely looking at another failure soon.

A friend of mine who is a remanufacturer of alternators took one look under the hood of my 2010 and said "good you have the Denzo not the ford alternator". Unfortunately he doesn't get cores for the Denzo.
