want to bypass my ac, can't i just use a really short belt and leave the ac on? This way I could put the longer belt back on the ac for the 3 months I need it, and the rest of the time I could gain 0.25 hp from the reduced rotating mass? Would this affect the ac system negatively in any way by not constantly turning the pulley when the shorter belt was on?
Belt is easy to get on and off, and every little bit counts, I'm sure this would help more than the $65 alternator pulley (which is a very nice pulley btw.) I bought that saved me 3 whole oz...
Thanks...
If you don't occasionally run the compressor the seals have a habbit of drying out and then your compressor starts leaking. Other than that, you shouldn't have any negative side effects.
chances are its not gonna work, the A/C compressor will most likely be int he way of the shorter belt.. What engine?
if its the 2.4 LD9 you can do it. the only thing is that you end up running the ribbed side of the belt against the tensionner. i don't know the belt size but if you search for ac delete threads you should find it eventually
its an ecotec
you can just run the shorter belt, the compressor shouldn't be in the way.
this topic needs to be made a sticky.
I just did this a couple days ago. The 345K5 belt is $10 at AutoZone and it works fine. I found it helpful to remove all the plastic crap on the passenger side of the engine because that makes it a LOT easier to pull on the tensioner (which is a bitch in itself to move) and install the belt. This was on an Eco, btw.
About the seals...can they be greased so they won't dry out?
awesome, i'll try this out in a couple of days, doubt I'll feel any difference but every bit counts I guess...
No, the seals can't be greased... But you can have the system maintained regularly (As in yearly) to keep it in good shape. It's just one of those things people take for granted 'til it fails... like the EGR valve.
Go beyond the "bolt-on".
so, what belt do I need for an LD9? on another thread someone said it was the 350k5, and another person said it was the 345k5. I got both from O'Rielly's and neither one worked; the 345 was too short, and the 350 was too long.

How does that work...?
^ Are you sure you were loosening the tensioner all the way? I thought my belt was too short at first until I pushed a little harder on the tensioner, lol.
the 345K5 will fit on a LD9, but it is tight....and a PAIN in the ass. The 350k5 fit better, but after it stretched it started to make noise.
I'm running the GM bypass pulley currently on my LD9.

I've had luck by putting the 345 around the factory scissor jack with towels over the metal edges of the jack and using the jack to stretch out the belt just enough to work.
just becareful with the compressor. you need to run it once in a while cause inside your system, your lines contain oil to lube up everything. if you dont ever use it your system begins to leak easier. and you have more problems. just remember for example if you use your ac everyday it will last longer then someone that doesnt use it.
ECOtec DOHC
ld9 = 345k5 belt to bypass it, ive had it on both my cars just use some muscle and put it on there
Are you guys using the 345k5 with or without your tensioner?

You're going to need a tensioner.
well, I thought I had the tensioner pulled all the way, but I wasn't using a serpentine belt tool; my wrenches might have been the limiting factor...
the 350k5 was definitely too loose. I'm sure having different-sized pullies would change how the belts would fit, whough. (Maybe I should get some of -MD-'s pullies...)
Question: What belt should be used to do the same on a LN2?
Go beyond the "bolt-on".
Uh, on the LN2... I dont recomend using a shorter belt to bypass the A\C. I tried that with a 98 2200, and the brand new belt would slip on the water pump. I didnt know, so the car would randomly overheat. A few parts later, i figured it out. Damage wasnt to bad on mine but could be worse on yours.
