After measuring low voltage (less than 13v) at the battery terminals when the car was on, I decided to do the alternator replacement on my e90 335i. DIY without removing the Oil Filter Housing!!!
Ok, I was skeptical when I watched the video and he skipped the actual important part of... actually swapping the alternator without removing the OFH. I just did this replacement without removing the OFH myself and can confirm that it can be done. What I did was remove the airbox, loosen the charge pipe completely, remove serpentine belt from the alternator pulley, removed the cowl, loosened and pulled back the intake manifold, pushed aside all hoses that were in the way and disconnected the alternator. Now the actual important part. Push the alternator towards the front of the car, it has some wiggle room front to back. Then tip the top of the alternator towards the cabin. This should put the alternator at a 45*'ish angle and you can slide it out. Repeat this in reverse to put the new alternator in. I did this in the dark just now, taking a couple of swear breaks, in 2 1/2 hours.
Found another video where the guy just shaved off the plastic from the manifold airbox front right mount. That allowed the alternator to come out without removing manifold.
you should have shown how you slid that alternator back in place because it just magically is in place and I know for a fact thats a super tight fit. getting it out is one thing putting it back in the same way is not as simple
Wait, were you initially not able to get enough leverage or good enough angle with the lock plier on the T-60? Why did it skip the belt tensioner effort? That’s the part I needed help the most
I’m saying that because I’ve changed mine 4 months ago and only had one shitty video to go off of.. also it was impossible for me to take the alternator out without taking the housing off. Remanded alternators from advanced come with a thicker casing sometimes.
How long did it take you and how many breaks did you take before cutting back to the moment of alternator coming off. Because this is NOT a good way to do this. Just take the OFH off and get it done in half the time. Ask me how I know this.
@@Spoolzone yea I just realized I put ewg but I have a pwg tho lol,taking it off was a pain in the ass but putting it back wasn’t that bad, all u have to remove is the intake manifold(u don’t even have to remove it entirely as long as u can lift it a good 5-10 inches u will be able to get it off and back on) and as long as u got another similar alternator (most aftermarket alternators will be slightly larger) it will go back in smoothly without having to remove ofhg. Don’t forget to also replace the intake manifold gaskets and clean ur throttle body, I didn’t do so and ended up with a small vacuum leak lol
NEED HELP ASAP! For details and photos please visit the this link: www.e90post.com/forums/showthread.php?t=1727903 Something similar happened with me today. I was driving normally and then the dash went off but I started losing power and eventually things went dead and had to pull to the side of the road. Jump started but no luck. Had the jumper attached for like 10 mins and then somehow fired up to life and bought the car home but it was LIMPING. Being clueless I happened to check the engine light code via OBD and it gave me a P0015 and a random/multiple cylcinder misfire. Next day, I bring a new battery home from lordco with the exact specs, plug it in and all the interior lights come to life. I start the car but when i rev it past 3000 rpm, all the interior lights go off. Everything. I DID NOT REGISTER THE BATTERY AS OF RIGHT NOW. Now the car threw more codes at me, P1055, P1774, P1777, P1891 and the old one, P0015 was still there. I'm clueless and stuck as to what to do. My alternator has some greenish whitish thing all around it which someone pointed out is a leaking coolant but the car's built in readers via the BC button say that the engine oil and the coolant is full. or is it a faulty sensor idk yet, which might have damaged the alternator. Would find out soon. I'll go after replacing the alternator but I'm not sure yet plus the alternator is expensive. Please someone bring my car back to life as it's my daily :(
Watching this video and another I was able to replace my alternator WITHOUT removing the oil filter housing. Be careful if you do this because the tensioner is a B****.
