hey guys and gals 😉 ,I just recently bought an alternator off PearlS13… and I was just wondering if anyone has replaced their alternator by themselves… if so, how is the easiest way of replacing it… I really dont want to go and spend 80$ on getting it done… i m fairly good with using tools, and have done repairs myself … but like i said i just want to know the easiest way to replace it… any information would be great… thanx Chaz ---

I did mine in the summer, and if im correct… Take the belt off first, then there is a bolt on the top of the alternator, one on the bottom as well both 14mm i believe. Then get a light and put it on the side of the alternator by your oil filter, you’ll see a plug, careful not to break it, it clips out like the other electrical plugs through-out the car… And last, beside the plug theres a red rubber boot, pull it off and you’ll see a nut holding the power cable on, 10mm i think, undo it and your done… Remember to disconnect the battery. And if you have a amp meter, start the car, rev it to 2000 rpm and hold the meter on the positive and negative terminals of the battery, if the meter reads between 13.8-14.4 your alternator is fine… if its below those numbers its pooched. if its above, then iuno what the fuk is with your car, lol… Good luck ---

the alternator is locted on the left side of the engine looking down from the front of the car… i hope the job goes smoothly, but remember to draw out a lil diagram of how the bel;t goes on, thats all you need is to finsish putting the new alternator on and forgetting how the belt goes… ne ways thanx a lot to everyone for ur input! thanx again chaz ---

well i just finished putting the new Alt on and shes running great now… ummm just a change from shiftKrunk’s input the bottom bolt you take out is a 14mm (so hes right), but the top bolt is a 12mm, just to make things a little easier for those who are gunna tackle this project themselves!! chaz ---
