I love to purchase aftermarket parts, but would never purchase this again.  *DEFECTIVE*

Poorly manufactured.  I replaced this pulley bracket trying to save money from going to the dealer, but it backfired on me.  I love to use aftermarket products whenever I can, but I would not recommend this to anyone.

After replacing the fan pulley bracket (which was part of larger project to replace my radiator, fan clutch, and heater hoses), I drove my 2007 Nissan Xterra around town without any issues.  After roughly 20-30 miles of drive time, I start to hear a "chatter."  Before I could pull over at the next gas station, I hear a large "crash" which I found out was the bearing separating from this bracket...sending my [plastic] fan and fan clutch straight through the BRAND NEW radiator, condenser cooling fan, as well as tearing my brand new serpentine belt and breaking the plastic fan shroud.

After calling Amazon, their only remediation (in accordance of their policy) was to replace or refund the pulley/bracket, which is probably fair on their part.  But it does not help the $350 bill I had to pay to replace the parts (plus the extra time to get this all replaced AGAIN).

I hate purchasing parts from the dealer as much as the next guy...it's expensive...but this is something you should REALLY consider.  I'm sure people have had luck with them as well...maybe I'm just unlucky...but this one is pretty important and can cause a lot of damage if it is not quality.  Hope that helps.

The "T" on the hitch was off-center and crooked.  Plus, returned it due to defect and was charged return shipping.  BS!  If the product is defective, I shouldn't be penalized!

Apparently the piece was defective. But then again the dealership may have lied to me so I'd buy their piece. Frustrating

I had to take the vehicle to a detail shop to fix what the product did to it.  I would not recommend it to anyone ; unless they want to spend a lot of money to fix what the product should have done.

They sold and shipped me a "complete strut Assembly" funny thing it wasn't complete. The "new" strut never had a bearing installed. My mechanic was the one that discovered that this item was defective. Whether the item as purchased yesterday, a month a ago, or two years ago; this part would have never worked. They sold me a defective part and could have seriously caused some damage to my car and possibly an accident.

Absolutely never again. It's a good thing they didn't put a 160day warranty on this thing cuz then they'd be replacing it. Supposed to be original but it's either re-manufactured or a crappy aftermarket knock off. I'm only giving 2 stars because at least it was cheap

Have a terrible time with after market, so I'd rather pay a little more for a product that doesn't give me fits and starts.

I just received this car for my son. After we installed all part, we find a broken line in it and we connect the car's charger several hours, but it doesn't work and all press buttons don't have any reaction. This product cannot return and replace. Beware to buy it!

As promised: I'm back to bomb rate this particular product.  Had a second one failed within the following month after the first one did out of the box.  I've replaced all of them since with OEM product. This last one cost me a lot of unnecessary diagnostic time and money (who suspects an item out of the box/new to be defective?).  This company's QC/QA is equal to their product: "junk".  Their customer service equally disappointing.  I could not resolve issue with Amazon as "warranty is through manufacturer" and I was left holding this bag: six useless Spectra "Premium" (what a joke) ignition coils.  I wouldn't recommend these to anyone.  I worked on my auto too long, removed airbox (labor intensive job to get to the back 3 cylinders) THREE times because of these garbage items.  My previous review below:
I had bought six (6) of these only to have one fail well within 6 months of installation.  I have rated this item 3-Stars THUS FAR as I'm giving manufacturer the benefit of the doubt (oddball/small Q/A issue: one of six) and the price was excellent BUT, if I have any other ignition coil fail within the next 60K miles, I will bomb this product/rating. Product is made in China.  Working through Amazon Customer Care (excellent outfit!) for replacement.

Seller/shipper did the usual excellent job at getting the item to me.  I have purchased other ACdelco parts from Amazon in the past with satisfactory results.  Unfortunately, the specific item I received this time was manufactured with deep gouges in the metal tubing portion of the hose assembly.  Had I not seen this prior to installing it on my car, I would have risked catastrophic failure of the part and a serious crash due to brake-system hydraulic failure.  Quality control is the responsibility of the manufacturer, ACDelco.  This part should never have left the factory in such terrible condition.  I will inspect all new ACDelco parts more carefully from now on since I almost didn't catch the problems with this one.  While I find that Amazon's purchase/return process worked just fine with this transaction, I no longer have the confidence in ACDelco's quality that I used to have. This review was edited by me, the author, after initial rejection by Amazon.

Product cost me $800 in repairs because it was defected.  Would not work at all, broke air intake manifold bolt.  Cost me $800 in repairs. XXXXXX

Looks like you can't trust aftermarket engine mounts. Second time I received an engine mount with mounting holes that don't even line up with the chassis. What happened to quality assurance? I will be returning this and spending my money on OEM products, the money and time I wasted on this would justify the higher price for a good solid OEM product.

**Follow Up from July 2015. It's now Jan 2016 and the part has failed. Great. I get to waste even more time replacing it.**
This is NOT a MOPAR part. OEM means Original Equipment Manufacturer. It does NOT mean Original Equipment "Manager" as is printed on the box this part arrived in."OEM" is the name of this company. Sneaky. I don't like sneaky. I didn't notice until the part arrived.
The part itself, above the bottom portion, looks Chinese and feels just a bit lighter than the original. The cylinder cover is shiny steel, unlike what is in the picture. I expect it will soon rust. The ONLY reason I gave it 3 stars is because it does fit well and as far as I can tell, it does work. It did arrive quickly and well packed. It included two gaskets and the two larger mounting bolts.
I installed this part on a 2006 Town and Country with the 3.8 motor.
If you have this vehicle or the Caravan, keep reading. I used a wobble extension with a long socket which did work, but the problem is that the bolts have a flange on the top that prevented the bottom bolt from unscrewing all the way when it bumped up against the alternator. Literally a few millimeters off. I had to remove the wheel and splash cover, then loosen the serpentine belt and then move the alternator in order to fully remove the bottom bolt attaching this to the motor. It burned up 4.5 hours of my afternoon.
Had I known this beforehand, I would have just paid the dealer to replace it. Thank goodness my neighbor helped me. He had the tool needed to loosen the belt. I did NOT include this labor in my rating because that has nothing to do with the part. Just some advice.

So where to start on this one?
I went in hopeful. I'm a huge fan of E3D products, and at a third the price, I thought I'd give this clone a shot.
The best thing I can about it is it looks the part.

It comes fully assembled, needing only some tightening once installed. Or, you would think so. I wanted to be thorough, so I disassembled it to get a feel for it. So, the first thing I noticed was that the PTFE liner only went to the bottom of the actual bowden connector, not into the actual heat break. Had I not caught this, it would have caused an immediate issue.

So, taking it apart was another issue. There was serious binding on the the threads of the nozzle and heat break. After a careful ten minutes or so I was finally able to get everything apart without any damage. Looking close at the threading, it became immediately apparent that the materials and tools used were all of pretty low quality. The threading was jagged and rough, causing the binds. Additionally, the nozzle's hole was not cleanly machined and had some sharp edging that would have caused scraping along prints. I had to clean that up before use. It's also worth noting that the nozzle diameter is slightly off, which can cause slight issues with the quality of your prints.

During reassembly I had to feed the bowden down to the stopping point in the heat break. I treated this more along the lines of the E3D Lite, since the heat break was built like a mix of the two, but with the PTFE gap going all the way down to the bottom of the heat sink. In an actual V6 it stops a little farther up, but with the Lite is goes down nearly to the nozzle. Had I not done this, it would have lead to issues with filament feed and jamming.

And on jamming: any print more than a small part jammed and oozed. I couldn't figure out why. That is, until I noticed my ABS actually starting to SMOKE. It was burning my filament! I used the thermistor settings in the product listing, and whatever was sent with my hot end did NOT match. Setting at 230C, when measured by my thermocouple, was actually at 248C. This has two major issues, the first and most noticeable being heat creep, which is the filament getting too hot and melting further up the line, causing it to bunch together and jam. The second being that at above 245C PTFE starts to burn off, and it releases fumes that are neurotoxic. This is no joke you don't want to be breathing that stuff in.

I had another, known accurate thermistor available that fit perfectly and I went back at it, wanting this hot end to be worth all the hassle. After doing this, no more jamming, and printing reliably, albeit not with the best filament flow. And I tested this in both bowden and direct feed configurations.

Another side note: The fan doesn't fit snug against the injection molded shroud, causing a decent amount of airflow to come out the bottom and directly on the print. With ABS, this was causing first layer issues until I covered the gap on the bottom with a bit of kapton tape.

I really wanted to like this hot end. I really did. But its a poor imitation of the real thing, and while it passes at a glance, it just doesn't function nearly as well. Even as someone with a ton of printing experience it took a ton of work to make this usable, after which the quality still lagged behind the most basic of hot ends. Anyone going into this building their first printer would have a nightmare with this, and have no idea what the issues were.

In the end, save your money, no matter how low the price drops. Your time is more valuable than the amount of effort you'd have to put into this hot end.

I bought this product in Nov. However, i didn't open it till yesterday since my current one was working on and off so was lazy to get it replaced. Yesterday i dropped it off with my mechanic and he said, this is a crappy product,doesnt look good and he said it might not last long(not more than a few months), since i already bought it i asked him to goahead and replace it and when it try to get the existing part out...it doesn't FIT. Now i have to get a part from the dealer to replace this. Waste of time/money and peace of mind. Now since its out of return period, i cant even return it.

I hate getting remanufactured items, but decided to give it a try.  Old pump leaking from the main shaft. Got it off and the new pulley put on this new unit with the 7874 Pulley Puller and Installer Kit, by far the most time consuming part of the repair.  Installed new pump back in the Jeep, cranked it up, turned wheels back and forth, power steering level good, shut down, all done!  Get cleaned up for a test drive, crank up the engine and power steering fluid sprays all over the bay and out 5 feet! Leaking from the center shaft! Now I get to do this job again, tomorrow, with a part from the local Oreily's Auto Parts.

Extremely disappointed! This part FAILED after only 30 days of use. Had it professionally installed! Now I've lost my total investment in parts and labor and must pay full price for the shop to order their part and do all the labor again! I'm so angry because we had to return this part once already because it arrived bent up. I am not happy. Do not buy this part!
