I am fairly new to this forum, but I must say that my hopes that this would be a more useful/ informative forum than the maxima forum i used to belong to has not come true so far. for instance I posted a question about coolant hoses for a 1992 e36. I got like 3 answers, only one of them useful in any way (thanks to the guy who did post). However, here is the scary thing... lots of you guys running around in cars that old or a little younger with ORIGINAL coolant hoses!!!!! ten years on a rubber hose that supplies the life blood coolant to your car and you dont know crap about when it was changed or if it was ever changed? These are the same guys that are worried about 6 HP from a fan delete ?

Ok, so maybe just maybe I was hasty, but then some poor guy is out there with a car he can't turn off and there are 12 posts to answer his emergency. Only one post had anything useful to say, the others best as I can tell did nothing more than want to see themselves in in print. To say nothing of the erroneous information about how auto electrical systems work. I especially love the guy that so "clearly" explained but no battery = no fuel pump. no fuel pump = no fuel flow. no fuel flow = no running engine. If you haven't yet, just disconnect the negative battery terminal " News flash there dude, your car will likely run until it runs out of fuel assuming you only pull the negative battery terminal becuase a a fantastic new invention that BMW has used on their cars called an ALTERNATOR!!!! depending on the draw from the electronic ignition the computer and the fuel pump, the alternator may put out enough current to run that car at idle until it runs out of gas. Other guys are talking about blowing fuses and frying electronics, manula tranny versus automatics, etc. The simple, safe answer is pull the fuse from the fule pump. Is this dangerous or harmful? well gee I hope not since that is the very same procedure that the FACTORY describes for removing pressure from the fuel system before work begins.

Going back looking at the posts responding to this gentelman's emergency, I see lots of pretty pictures of owners cars, but not much in the way of info. do you think that they guy cares what your car looks like while his car is contuinuing to run ? or better yet do you think he wants to read about how tearing the dash apart is not a good idea because you cant get to some mystery kill wire?

My point is that there is nothing wrong with BS sessions but the forums should be a place for useful information not people who only want to hear themselves speak..

P.S. i also looked at some of the cars those guys that posted are driving... get to 100K miles yet fellas? did ya change your plastic impellered water pump, your plastic thermostat housing, and all 7 or 8 of your coolant hoses so that you dont get stuff out on some road and overheat your motor? Well since as far as i can tell most of you have not, I will post my results as soon as i do the work, and let you know if it is as involved as removing the intake manifold or whether a little grunting will be all thats required.

Your thoughts are always appreciated. I'll admit some people on this forum would rather post information reguardless of whether or not they know the answer to seem useful. However, I make it a point to say I don't know or to ignore a post if I don't know the answer. It's better to say you don't know than to give wrong or useless advice. There are a lot of knowledgeable people on this forum. I apologize that nobody could help you. Hopefully you'll have more luck in the future.

Anyways, you can easily check to see if rad hoses need replacement if they seem soft or brittle. Just squeez them. If you're really anal about it, you can replace them as often as you like if you don't mind refilling your coolant. I can't help you with your problem as I am only familiar with the M42 motor. However, on the M42 there are no coolant hoses under the intake manifold.

318's already come standard with upgraded aluminum thermostat housings and waterpumps.

Should I move/delete this thread?

nycbmw325is:

This isn't a forum of BMW mechanics posting in their spare time. It's a forum of ordinary people who all have one thing in common: [E36] BMWs.

Like any public forum, it's your job to weed out the valuable advice from the crap. We are a collection of people who enjoy everything about BMWs; which includes chatting about them and passing along personal experiences, sometimes in hopes of helping others.

I definiteiy agree with Autotechnica; to supply a guess as a response and display it as certainty is not just ambiguous; it's also inconsiderate, and makes the poster look bad.

However, to post a guestimate or a hypothesis based on experience and state it as such may help point people in the right directiron for their own problems.

Itt's actually quite odd, imo, that you would expect so much from an internet enthousiast forum.

The only thing that would/could change this is to have the forums more fine-grained; but then that just creates more forums to sift through when your looking for answers. (Assuming of course you don't find what you are looking for with a search.)

Just my 2 cents (CDN.)

no its, fine.

as for the alternator, please show me where it has wires connecting it to the fuel pump, ECU, fuse box, and every other electrical component in the car. When you remove the negative battery terminal, you remove the ground. No ground = no complete circuit. No complete circiut = no power flow. Thank you for playing. As you seem to have a good grasp on alternators, I assume you also know that they produce AC power. I will assume you also know that the electronics in the car are all DC.

Further, removing the fuel pump fuse still does nothing to turn the car off. the engine stops, but his key is still stuck to run, which will still make the battery power everything until the terminal is removed.

A response to all of you guys so far... You are right about the nature of forums, and I always try to weed out the fact from the opinion, as should we all. However, when people state things as facts, that are either their opinion or flat out wrong, and others relie on that info then it harms not only that person but the usefulness and integrity of the forum at large.

P.S. as to the "wires" going to the ECM, fuel pump and ignition from the alternator, try this little experiment. Take a little test light that shows continuity and and start touching various metal parts under the hood. you will find that amazingly enough, many of them are electrically connected. The principle is known in automotive speak as a 12 volt negative ground system, where the vast majority of metal parts are grounded. even though your alternator may have a big thick ground strap on it, it would likely work just fine without it since it is anchored to the rest of the big block of metal which is all part of the negative or ground. If you really truly dont beleive me you could of course try disconnecting the negative terminal, but I would caution against this as there are sensitive electronics that may not be happy about doing so (per the owners manual warning )

keep in mind the average age of the members on this forum is about 17. This provides for a lot of excess chater, and while I'm not nearly as youthful, I have sucombed to the horse-play nas well.

On the flip side, I have learned more about e36 cars over the past six months on this site, than I have from my mechanic and other BMW owners in my community combined. It is a priceless resource for me, and I feel lucky to have found it.

Regarding your advice for other e36 owners, it is solid, and we thank you for it. You might notice that the brunt of your statements are found in the FAQ section of this site along with many other helpful hints.

I thought it wasn't good to un-ground something with power going to it? Doesn't that run the risk of blowing electronics of all sorts? Pulling the fuse would interrupt the power just the same as pulling the positive terminal on the battery, just without killing ALL electronics.

nycbmw325is, I can agree with your argument, but this isn't just a forum to help people. Thats what the DIY and FAQ sections are specifically for. But most of all, the way I view this forum is a bunch of e36 enthusiasts who have picture sigs and lists of mods as a means of showcasing their cars and their knowledge. Its a way for all of us, to see what people are doing to upgrade/improve/style/etc. their BMWs. If they tell us how they did it, awesome. If they don't know and had a mechanic do it, at least they are honest and humble about it. Its a way for us to show off our prides in these cars. Just driving down the street, Bob the next door neighbor won't know the difference between an ODB II-ODB I conversion and a strut tower brace. But here, if we see someone do this swap, its pretty damn deserving of an applause because most of us know what kind of potential that provides in our Driving Experiences. Pretty much everyone in here knows something or can bring some special knowledge or impact to this forum, however not everyone will know everything.

Half the fun of being involved in this forum IS sifting through everything trying to find your answer. By doing that, the amount of knowledge gained is incredible. I know Hondas and Acuras like the back of my hand. Then I bought a BMW and didn't know all that much besides the basics. But since joining this forum, I have learned SO MUCH about my BMW. I know I may say some stupid things and I may say some smart things as well, but all I know is that this is a good means to education about my BMW without having a dealer charge me $50 everytime I have to change my oil. Take this forum for what it is. Its not a Maxima forum, its a BMW forum. I enjoy it here as much as everyone else does and as much as I know you soon probably will.

Welcome to the forum and I hope we can provide as much assistance and entertainment to you as well. Feel free to show us your process for changing Rad. hoses. With your input, maybe a lot more people will start doing it because I definitely understand where you are coming from. A blown radiator and cooling system is nothing to mess with...I dealt with it in my late Integra and its a bitch...Later fellas!

hello

i'm 17 and rather for the most part, inexperienced in my knowledge of cars, but not my love for BMW's this forum has taught me so much. I remember before i even posted for the first time, i sifted through most of the FAQ's and previous posts about any topic i could think of. I realize that chances are, any feeble question i could present, was most likely already talked about by someone ... whether it be other enthusiasts, or a newbie like myself. I've learned more from reading others posts and sifting through info, than from posting a few of my simple problems. There is a wealth of knowledge out there, and most of the time, you'll gain more of it from reading and searching for it, than waiting for a few fellow BMW owners to fully enlighten you.

Its most likely out there somewhere, and i find i can get to it quicker by scouring the net rather than waiting by my computer for an answer to my post. And if its NOT out there ... then maybe people HAVEN'T discussed it before. And if there has been no discussion, chances are, maybe the other memebers don't really know off-hand ... because they've never really thought about it in detail. How many views were there on your Coolant Hose topic? Many times, if i read somethin that i don't know about, i leave it alone and don't mumble some obvious fact just to see my # of posts go up one.

Many times, i find that i post, and read others who post, to be reassured. They ask a question that they have an idea about, but they would rather have it be cut and dry what they should do. No one wants to mess up their car with something stupid. You obviously know somethin about cars ... and obviously know what to do about coolant hoses too your comment about how you can't belive we're all running around with old, cracked ORIGINAL hoses proves that you have your own distinct idea what what you should do w/ your hoses. But it is nice to have people say, "yeah, do that, i did and its better now ... " There's not always gonna be a direct yes or no ... or the kinda response that you want. Your not always gonna be reassured, but that's life. If you know that much about cars, trust yourself a little to do somethin w/out the approval of others. Do what you want in order to keep your car (and its hoses) up to your standard.

Sites like these are not perfect, and someone doesn't always know your answer. I'm 17 and i sure didn't know about your alternator explanation. So chances are, you are more car saavy than a a bunch of us (me at least) Trust yourself enough to maintain your car w/out the go-ahead from a bunch of other e36 owners you met on the 'net. This forum really is great, and don't get flustered cause someone didn't reply to your question, and don't label the forum as "uninformative" because you didn't find the info YOU wanted. There is a HUGE amount of into here ... and other places where you can learn about your car.

And congrats on your bimmer. '92 325is --- my car too ... and doesn't she sound pretty?

nycbmw325is:

He said that he had no idea about cars. If he had some idea or felt comfortable with his car, he wouldn't be asking how to turn it off to begin with. Would you feel comfortable tearing apart a dash that would cost you a thousand dollars to replace new? What you need to do is go get on a forum with all mechanics and see how well recieved you are there. You can't go to those places with out having a Proffesional Mechanics knowledge about cars. We are all here because we love cars, namely BMWs. Most of us can not tear our cars completely apart. In fact I would say no one here could strip their car down piece by piece and then put it back together fixing everything that is wrong with it.

Coolant hoses are things that most people don't replace until they break. Theres no reason to. I have never had a car where the hoses have broken. No car my family has ever had has had a broken coolant hose. Some people keep detailed records and are OCD about their cars. Thats fine. But before you tear into other people for the way they maintian their cars and what they are worried about, such as the "6hp from a fan delete". Remember that it is their car and they can drive it off a cliff or set it on fire or let the coolant hoses break or even replace them and don't remember when.

Also it was mentioned to pull the fuse for the fuel pump, in fact I do believe that I mentioned it. Oh wait... I did. And please excuse my apparent incorrect information about it may blow a fuse or cause other damage. Because as it turns out I am not a BMW master tech. If your going to complain about the forum leave. I'm sorry that no one could give you proffesional mechanical assistance with you precious coolant hoses. But if you don't like the free and friendly help that you can recieve here and all of the pretty pictures of cars, then leave. We are not going to change for you or anybody else. And we certainly won't miss you. I'm sorry if you are now offened by this but its the plain and simple truth. Since you want to bash the forum, others will still be nice to you, (good job Autotechnica and El pres and others), but I don't like it.

wow. i go lunch and so many new responces.

getting back to mine:

I understand 12V ground fine, and really don't see how it applies, other than your claim that the engine will continue to run even if the ground on the bat is interupted at the bat. If I am wrong about what you saying, please correct me, but that is how i view it.

Here is where I will explain, again, why removing the bat terminal will halt the engine, with an emphasis on the ground vs fuse. by removing the negative battery terminal the battery loses its ability to flow power, even if everything else is still grounded and the alternator is still producing power. As I understand it, you claim that pulling the bat term will not kill the engine due to the alternators power output, whereas the pulling the fuse will. The problem with that is that the line is fused to the battery, not the alternator. If the batteries ability to flow power has been circumvented, then the fuses will not be getting any power to interupt. Ergo, the engine stops the same, as well as killing all other electronics and preventing the battery from draining itself of power overnight.
