That's why they don't have any money to begin with. They don't understand these concepts. Then they come in a week later wondering if we approve of installing a used fuel pump because theirs died and they can't wait for a new one to be shipped in.

The mentality of replacing things as they break is just as costly and more inconvenient than preventative maintenance. Wait for my water pump to break? Really? Why would I do that? Most cars get a new WP around 100K. Nobody waits for those to break unless you are stupid and like over heating. Expansion tanks seem to blow up regularly around here. That also makes sense to change. I've seen several fan explosion threads in the past couple months. There are specific parts you need to do PM on. Other things can wait (VCG for example).

To the moron who says over heating will only cost you a head gasket and a milling of the head: How much do you think that costs? It's well over $1000 and you'll still have a broken cooling system to fix. No, you won't have to get a new engine, but have fun without your car for a week while they do this work. You'll replace that broken WP that caused it or whatever, then the next day your ET blows up and you lose another head gasket. This time they can't machine it because you can't put a head gasket that thick on. Peace engine. Anyway, $500-700 now would save you thousands in the future.

*Awaiting response with anecdotal evidence that their PM didn't work because some other part broke*

At the very least I think replacing the expansion tank, water pump and thermostat will save any drastic coolant-exploding-side-of-highway experiences and more importantly overheating.

Replacing a headgasket and warped head is an expensive PITA

Wow, I was a non believer, now converted

For starters, I used to be a "don't fix until it makes a noise or leaks" mentality. At 110K miles and thinking that Expansion Tank stuff is BS, i got the pop and smoke of the ET Failure. Luckily it popped right near my house and I had it towed home.

Hoses, ET, WP, Thermostat, all replaced. You have to figure you are going to replace this once while owning the car, why wait until it fails, replace in the spring/summer. I replaced mine when it was 0 degrees outside, the garage heater got it up to 40, but repairs are much more fun and easy when you plan them!

Note: Yes I did use an AZ water pump since I had a credit there, 15K miles and pump is fine.

I also have 15k on the Autozone waterpump I put in a pinch. The bearing on the old pump just started making noises and it bugged me enough not to wait for something online. The one I put in was a quality unit and I have no doubt it will go my standard WP interval of around ~60k miles.

That said I went to purchase the same pump for the other car. What they brought to the counter was by far NOT the same pump. Whatever it was, even I knew to stay away. Probably changed suppliers, I don't know.

I think OP needs to make yet another self-appreciation thread where he can talk about how knowledgeable he is, how his way is the ONLY way to maintain BMWs, and inflate his ego even more.

Seriously Mango, give it a rest. Providing part numbers and information is great but the whole forum doesn't need to be constantly told when they should change their cooling system. Are you just on some mission to get the most amount of replies or views in your own thread or something?

I see much debate among you veterans and I can understand some your comments. However I think this post was geared toward us NEW owners. So I wanted to give a shout out of thanks to Mango. As stated before I just purchased my E46, and with the shopping list of other things I need to fix, the cooling system eluded me…until this post. I took apart all the cooling system components and found my expansion tank and tank holder just over a year old as indicated by the mfg lable. However the radiator had a mfg date of Dec 2002 and by the looks of it has been in the car since new. I sprayed it out and black water came through the veins, being that I live in AZ temps in the summer are in the 100s and 110s like dznuts007 in NV. I’m sure this would have been a problem for me this summer. Also found the fan switch leaking at the lower radiator hose too. Sure I would like to spend my money on angel eyes or some other cool stuff, but gots to take care of the go go first,

so...


thanks again Mango!

p.s. will also be replacing the water pump and hoses too.

I think you are missing the point. Most people skip over the Stickies when they join the forum. I didn't, but I'm old, and came here for the wealth of information. Mango noticed a lot of newcomers lately, and simply wanted them to be aware of the cooling system issues. Nothing wrong with that.

Mango is a very black/white person. There are no shades of gray for him. Something is, or it isn't. Nothing wrong with that either. For me, it provides a nice balance to my many shades of gray.

I don't think it's an ego thing at all, at all. We all have egos so, to an extent, every post we make is an ego thing, including this one.

Wash your car, clean components, change the oil, etc, etc. Since you're new and only did this other thing because someone told you.
You do not need to remove the radiator to clean it. You could have used a hose. Hours of your day saved to do other things. Thank me now.

Sure this is a forum and people giving advice to help out is all good. Which is exactly what this thread was for. All good.
but..
i do see how some point out there is a Sticky at the top and placed there for this very reason. i could bump a dozen threads pertaining to this same thing written years before that Sticky too. but i don't because i figure people come to a forum to learn and the things they may find the most useful in one place are Stickied..no??

I think the best post would be remember to examine one's car or have it inspected.

How many people read this thread before reading any other?

http://forum.e46fanatics.com/showthread.php?t=523290

Based on some of the questions posted in the past week, I would say quite a few newcomers zipped right to the "Post New Thread" button without reading any posts. Some have been justifiably flamed, but others have not. Rules are made to be broken, it seems. When you see a 55 mph speed limit sign, and everyone around you is going 70 mph, how fast do you go?

Another problem that newcomers have understanding terms like "sig" and recognizing that underlined words are actually links. (Hard to imagine, but true.) It takes a while to learn the lingo of this forum. We should keep that in mind.

As far as the "Do It All" suggestions, they are just that. It's up to the reader to determine what really needs to be done. If they can't, then they should do it all. There's nothing I've found in the suggestions that will hurt the car. It might hurt the wallet, but not the car.

I took it out because I have ordered a new one to replace it. I take very good care of my cars and I want to start off getting this car to a high level of service.

I just dont know the history of my new car or how it was taken care of (or lack there of) etc. So what better way to start off the best way I can, (money wise) and keep it up from there.

I still have a few things to do, but Im taking it little by little. Once all the yuck stuff is done i.e. leaks, tears, misfires etc,

I will move on to the fun stuff for the car. Cant wait for all that, especially seeing some of the rides on this forum.

Kaktusjaque--awesome. That's exactly what I like to hear.

MKodama, I am in general every single day almost the entire day on weekdays. Lately we've had thread after thread asking what's wrong w/ my cooling system?! I made a comment that people were passing over the cooling sticky. The whole point for stickying the sticky was so that people can click on it. Apparently, I've found, a lot aren't. So by providing yet another PSA on the very most important thing on our cars as summer is approaching, I thought it would be a good idea to promote healthy discussion and sort of a Q/A session for new members. And apparently, it's serving its intended purpose. Lots of people lurk so that's another plus. If I made 10 threads on this subject, I'm not sure why you'd have a problem with it. It's a very important topic that new people need to understand. And this thread is also for those who have or don't have the parts and have been putting it off.

As for the radiator, Alex. Do you have a special technique to use? Because the condenser is sandwiched right up against the radiator and I really don't know of a way to efficiently clean it out besides removing it. I'm actually looking for a good comb to clean my condensor fins. I think I saw them at Harbor Freight.

You should have a Grainger nearby. If not, any good HVAC supply house should have them.
