Loosening the Belt?

CNUco2007 · 09-23-2006, 08:21 PM

I need to swap out the alternator with a HO alternator, but I can't figure out how to loosen the belt. On my last car there was a specific bolt you turned to loosen it, but I can't seem to figure this one out by just looking at it. Anyone here care to help me out? thx

Whats the voltage/wattage on the alternator? and where did you get it? is it for SI or Coupe? or both? direct bolt on fitment?

CNUco2007 · 09-23-2006, 08:39 PM

200Amp alternator... not sure what voltage... i don't have it yet lol. You can find out more here:

My new HO alternator

Only difference is mine is for an Si, and mine will be a "winkle red" cuz i also plan to have my Valve Cover powdercoated that same color. my only problem is after looking at the setup, I have no idea how to get the belt off

I had a high output alternator in my last ride...worked well. I'm assuming there is a belt tensioner on the K20 or R18. Pretty difficult to mess with without a tool from Honda, however I did it on my last ride (J30) without the Honda tool, but I can't recall how...it was a real bitch though I remember...

a simple open end wrence will work. what u need to do if irecall was take an open end wrench to the belt tensenior bolt, and push up, like u're about to unscrew the bolt, but i think u need to give the tensioner a little boost so that you dont break the bolt tension and unscrew the bolt. the tensioner will slide right up and u hsould unwrap the belt. thats what it looked like when my mechanic did it.

CNUco2007 · 09-24-2006, 03:37 PM

do you know which bolt was the tensioner? That's basically what i was looking for cuz that's how ti worked in my lumina, but everything looked like it stays in place. haha thx for ur help btw.

yea, if u look very carfully, u can see the pivot, it will be right there, it's right by what looks like the brake junction box. where all those very small metal tubes go into. it's about 2 inches in diameter. the way you can tell is by pulling the belt w/ very firm pressure, somethign will give, and thats the tensioner. u'll see it piviot in adn out. the tensioner is the third bell down, i belive, it wont be right in there. so thats why an open end wrench is needed.

the best test is the tug test. give a nice tug and u'll see the tensioner working. also, make sure u route a diagram before dissasebling so u dont forget for wtvr reason how to put it back together.

edit,i'm sorry, he used an open end wrench w/ a breaker bar for more leverage as the open end wrench wasn't enough to open it, well mainly because the wrench was too short that it didnt' extend past the engine bay.

thx, i found it. i didnt even think of tugging on it haha. now I just have to get it loose :P

radiocontrolhead · 09-24-2006, 06:05 PM

NO! u dont lossen the bolt! u use the bolt to help u loosen the tension, not the bolt! thats why you need to give the tensioner that little boost by tugging the belt and it wont put as much stress on the bolt and lead it to unloosen the bolt? u'll understand.

oh i know that. that's what i meant haha. It just doesnt look easy cuz there's not much room to work w/

if u take a open end wrench and use that indent in the wrench to shove it arond the bolt, u can use a cheater bar to hold it up, u just need to give it alittle boost so that u dont break the torque on the bolt.

CNUco2007 · 09-24-2006, 09:11 PM

ok. i'll give that a try as soon as i get the new alt. thx for the help :)
