Product as advertised

Fit my 2010 2.5 non-turbo Forester just great! My old belt didn't show visible signs of wear (see pic) but since I was already replacing the squeaky alternator belt I figure why not - my Scooby has 75,000 miles so it's overdue for new belts anyway, in theory. I'm not sure I believe the Gates video when they show you how to use the tool and claim that the AC stretch belt is designed to wear away at the same rate as your regular serpentine belt. The AC belt, while it does spin as much and is shorter than the serpentine belt, only has load on it when the AC compressor's clutch is engaged. Meh. The Gates 91031 tool is a must when replacing the belt. I posted a review there but basically, you should watch the video a few times on how to use the tool before going under the hood and while you're replacing the belt. My stomach was a little queasy as I cut the old belt off like it showed in the video. It was the hottest day of the summer and if this didn't work then I'd have been out of AC! Fortunately, its so easy a caveman can do it.

The belt is made very well with a quality not unlike any of Gates products. I've put about 10,000 miles on it so far and it still looks good from a previous removal and re-installation. It's still too soon to talk about wear and such, but from what I see so far, its a good fit. I'm trying to offset the bad reviews because, although I understand the switch to a stretch fit belt is a DIY-unfriendly change, it was Subaru's decision to use these types of belts. The belt itself is made well and serves its purpose. I DO have my gripes about the use of stretch-fit belts that I'll address below. First off, the old tensioner pulley design on quite a few of the older model cars had (in my opinion) a bad tensioner design. For those who have the old tensioners, they were set to apply tension at an ANGLE rather perpendicular to the belt. This would cause unnecessary strain to the tensioner and subsequently they wind up with customers who get damaged tensioners. Instead of redesigning one that applies tension perpendicularly (90 degrees) to the belt, Subaru decides to slap on these stretch fit belts. Now you are left with a few options on getting an A/C belt on your car. Option 1: There are mounting points on some of the new engines which could be mounted with the old tensioners, just do some research to find the right tensioner and belt and you can convert to the older but easier and cheaper (in the long run) way to replace your belt Option 2: Buy a proper install tool. There are "universal" ones that wont work. Some tools require the A/C belt to be on the outer part of the crank pulley. My 08 Impreza has the AC belt on the engine side of the pulley. Option 3: It is possible to get the belt on and off with a bit of muscle and with a 1" inch width nylon strap (about 3 or 4 feet of it will do). Just use the strap to pull the belt towards you as you rotate your crank to "walk" the belt off the AC pulley. Once the strap gets caught between the AC pulley and belt, just use the other part of the strap to pull on the belt to continue walking it off the AC. Getting a new belt on is more of a challenge, but can be done in the same fashion. Having someone to turn the crank as you walk the belt back ON can make this easier. You'll have to pull hard and get enough initial tension so that the belt can hold on to the pulley's instead of slipping. I've done this successfully on my own with no damage and no problems, it was just a pain to find a method that works. If you are REPLACING a belt you can just cut the old one off. I have re-used my OEM belt when I installed a new crank pulley and put over 70,000 miles on the re-used belt with no problems and installed a new belt at my 90k mark. The old belt didn't even show any unordinary wear.

Thank you it worked perfect

This belt replaced the worn out ac belt. It fit and worked well using the gates tool to install it.

It’s a stretch belt so make sure you have an installer tool. Worked great at a great price.

As described

Original OEM belt on my car. What else can I say.

Beaucoup moins chez que les voleurs de Subaru

this belt should be sold with the install instruction and tool .
