I just dont want to break the bolt head off. Thanks again for the people that are giving the good advice and help.

Normal thread. I think the guy that torques that bolt at the factory sumo wrestles on the weekends.

Another good point noted above.

BTW...why does putting a supercharger on a 4cyl car automatically mean that you actually know something or use common sense for that matter?

Where can I find the Serpentine Belt Routing Diagram?

Any guidance on this issue would be appreciated. I have spent two hours trying to loosen the bolt at the bottom of the alternator to no avail. I have tried some pb blaster as well. I have nothing to show for my effort except sore hands. Does anyone know the trick to getting this bolt loose? The space is really awkward to get good torque so I tried a universal extension, but am still having no luck. The replacement belt only cost me $11 but paying someone else to replace it is starting to look pretty good.

^^ Do you have a breaker bar?

Klink10 · 03-20-2011, 07:45 PM

It will come loose. Initially I had to use a 1/2 " drive and move the ac line bracket. Now a 3/8 inch drive gets it.

bankrobber · 07-01-2011, 11:13 AM

Done. Very simple job. Not as easy as my Dodge Ram. Kinda a PITA with a sideways engine. Think I got the tension good. Just a FIY found the same belt on Amazon for 11 dollars after I already bought one from Autozone for 20 w/tax with 3 year warranty

othater · 07-17-2011, 11:24 PM

Whats the recommended belt brand and best place to buy it.
Thanks

bankrobber · 07-18-2011, 04:35 PM

In the South I buy from AutoZone. They always honor the lifetime warranty with no reciepts. Napa or PepBoys is a good place to buy also.
Use Part Number: 5040465 Dayco Brand

Thanks Bankrobber for the reply, I will go with Autozone with the 3 year warranty.

I think this is done and gone, but I just wanted to say that I recently did this to my Egg. She has about 90K on her and needed a new belt. The bottom bolt is on there REEEEALLY good. I had to use a socket wrench and put a tube on the end to extend the fulcrum and had to make sure the socket I was using was the exact right size.

heat, time, patients and penetrating oil is your friend lol.

im sure you already knew that. But I cant stress enough. Soak those stuborn bolts with penetrating oil. Heat is always good, Taps with a hammer. And time. Always time. Soak them go eat a sandwich. Come back and soak again. hell soak 3 times a day for a week. That bolt didnt become stuck overnight so its not giving up the battle in a minute. Also try different kinds of penetrating oils. I find that some work better in one case and others work better in another. Also get some Kroil or aerokroil it will make pb look like water.

Best Luck.

I replaced the belt going on 6 months.
Had to tighten the belt at least 5 times due to screeching.
Seems like the belt stretches a little every time.
(I marked the original location of the bolt)
Belt looks good, maybe this Dayco is just cheap or defective.
Probably will see if I can return it under warranty.

Are the gates any better or just go get the OEM from the dealer (on-line)?

Can someone tell me what the actual torque for the two bolts are?
Thanks

tigerpaw · 07-13-2019, 01:49 AM

othater, torque value for the 12mm top bolt is 14 ft.lbs
For the 14mm bottom bolt it is 40 ft.lbs. New belt deflection is 7.0 mm- 8.5 mm.

othater · 02-27-2012, 06:59 PM

Got a replacement serpentine belt.
Still a Dayco but a better quality one. Store would only give me credit for the same brand.
Originally went with the part number above. Didn't know they came in different grades.
So far so good.
Sure was easier the second time replacing.

Just used this guide - thanks all. Easy Peasy.

the rev · 03-18-2013, 07:58 PM

So, first off, thanks for the great guide!

Second, a word of caution to those who wish to undertake this:
You need to oil the crap out of the bottom bolt, several times, and let it sit BEFORE endeavoring to remove it! They apparently make these bolt heads out of pudding (on the 2010 anyway), and it will round right off with little effort. Oil it (from the backside) and let it sit.

Happy motoring!
