After all I tried because it was a tight location, I end up using a 10" Pipe Wrench and still removed front tire. On in a matter of minutes, but thanks for the tips.

Awesome Video. You saved me a lot headache. Replacing the belt on 2.2 ecotec on 2005 Cavalier with very tight space was extremely frustrating until I discovered your video. Thanks.

I am preparing to do the timing chains on my G5 -2.2-vin-F…I just acquired it about 4-5 months ago. As I was looking at other vehicle's, the dealer said they had a Pontiac over there & that she fired it up & it had been idling 4 a while-should have been a big red flag! They started it to hide the noise the timing chain makes at start up! I ordered a new tensioner & replaced it(thank God that I had a small, extendable magnet within reach because the tensioner came out in pieces & would have fallen down into the timing chain compartment) As I was shopping for a new serpentine belt, The question kept coming up asking if the A/c compressor has a triangular weight or a circular weight on the compressir-NEED TO KNOW WHEN BUYING A BELT! MINE IS TRIANGULAR!!! What length is your belt?I know they range between 39.96"–to–40.625". I was then told the model with a/c (triangular weight) takes a 40" belt…I am acquiring every part needed to change the timing chain's, & water pump! Then I noticed my belt was cracked up so,Just in time!!!

I just used my 3/8 drive ratchet now if you have one with a flex head that works even better then you're straight 3/8 drive ratchet which is what I use on my 2004 2.2 4 cylinder Chevrolet Malibu

Why not remove the air intake box? This will give you much more room to work.

Just like was said already, the serpentine belt tool you can rent is useless unless you want to cut and weld it at a 45 degree angle. The angle is completely wrong to be able to use it on 2005 Cobalt.

Beautiful work, good sir! My car is nearing that age where the thought of old parts inside of it makes me shudder. Thank you for this wonderful video and information. I need to replace the serpentine belt as well as a/c condenser in my 2005 Chevy Cobalt. Apparently it has an issue where the a/c condenser fails at a random point taking the serpentine belt with it. Good Times.

Anyhow, thanks a million for this! Should be fun doing it too xD

you worked entirely too hard for that. check out the haynes manual for instruction.

after doing this repair today I have some advice: 1) don't bother with a serpentine belt tool. we rented one from O'Reilly's and if was totally useless. it was tool long to have enough clearance to maneuver it to a position to allow it to fit I to the drive hole. My advice is to use vice grips to just pull the tensioner up. 2) the repair is a two man job. 3) do the repair in this order. remove the passenger wheel. Remove the plastic of the inner fender well and the splash guard covering the serpentine belt. Remove the air box. Have a friend clasp vice grips on the tensioner and loosen the belt. Grab the old belt and toss it out. While the friend holds the tensioner up, go under the car and wrap the new belt around the crankshaft and the compressor. Still while the friend holds the tensioner up, wrap the belt around the alternator from the top. Let the friend release the tensioner. Put splash guards and wheel back on.
