If you were truly a student of this board, you would have done a complete cooling system refresh.
And you've not given us enough of a complete history of the repairs you've done to your car? What is the mileage on this car and service history?
And perhaps most importantly for now, did you replace your thermostat?
And learn how to use the hidden OBC functions and set it to monitor your coolant temperature. Report back to here.
And verify that your fan is functioning properly?
I just hope its not the gasket/head ?
So what more should i do? try to bleed it the same way i did before?
Well as i said i've only had a mechanic to change the water pump and the mileage is 172k thats all i know
About the thermostat, no i havent replaced it.is it hard to diy?
and in the pdf file included in ur answer, what is the "left insturment key" mentioned in there? is it the one which unlocks the car?
sorry for all the nuisance, but a car to me is like a i know nothing about them, but im always eager to improve.
thanks for all the help so far.i will try to bleed it again.

Simple rule: bleed until you get no more air out. Then you're done.
Thermostat is easy DIY, and I'd do both main hoses at the same time along with temperature sensor in the lower hose. Always search for DIY's or youtube vids to watch for yourself if you think you are mechanic enough to do the job easily and you have the correct tools. You know your skill level better than we do.

Did you read the entire post #1 on this thread? If not, you should.

And oh yeah, we hope it's not your head either!

Sure it's boiling? What's the temperature?

Did you check with the OBC?

I thought that I would do my cooling system refresh but the eBay fan removal tool turned out to be crap. After finding Smolck's YouTube video, I may try the rubber mallet and 32mm wrench maneuver. It looks a little over the top but the mechanical fan is on there tight. If that doesn't work, I can always take the mallet to the fan and then replace it

It's burnt in my brain, I've been watching quite a few video's and reading DIY's. It was just aggravating to have a few hours to do the job and the fan was not going to let go. I'll have more time on Monday and will give it another try.

I thought I explained this 400 billion times already? Spray the fan nut w/ WD40 and let it sit 10-20 min. it helps. If you have the upper hose removed (which I assume you do) take your 32mm wrench (or appropriate adjustable wrench) and a large screwdriver wedged between the water pump bolts then it'll come off quite easily.

HTH!

400,000,000,000 times? I don't think you're there yet. Close, but not quite. Keep going.

What i noticed this morning, after adding some coolant to the ET together with removed bleeding screw (till its bubble free ofcrs). the top radiator hose got really hot and quite hard, also the lower radiator hose did get quite hot too it wasnt cold at all. so if both hoses are hot, does it mean its the head gasket?cheers guys!

oh, and the big fan just behind the radiator isnt spining at all. is that very bad? could this be the real problem?

You left out a few (E30, 2002, 635, etc) but yes. All of them.

My original water pump died today after 193K miles.. just heard a loud sound while driving and it's my fan hitting the shroud. Turned off the engine immediately so no overheat, my temp didnt even move past 12 oclock.. all the cooling system are NEW (radiator, hoses, thermostat, expansion tank) last year 15K miles ago and flush all done at the stealer...

I will DIY everything this time but question:

1: do i need to replace anything else when i change my WP (undecided yet between graf or Saleri)
2: do i need to do coolant flush or just top off will do? bleed?

Thanks all in advance...

@mango

I cant seem to find the the $54 saleri bump you mention at bmaparts??

Call BMAparts and ask for it. Saleri=BMW.

Replace anything you haven't already from my list.

You 100% need to refill the system AND bleed if you're replacing the water pump. Half the water will eject itself.

See #5
Looks like a twelve year old hose!
Cant seem to find hose #5 to order. Anyone know the order code off the top of their head?

why can't you find it on www.realoem.com when you plug in your VIN?

Then use www.furiousmethod.com to shop for prices on genuine BMW parts.


EDIT: Glad to be of service!

OK i will bleed after WP has been done (still waiting for parts to arrive)... but upon lots and lots of google and youtube vids - i have come up with 3 methods (so far)

1: posted on page 1
2: this 2 youtube video, they start bleeding while engine is running..



and this



3: similar to 2 but start the engine and rev it 5K (post here: http://www.e46fanatics.com/forum/sho...6&postcount=35)

there could be more methods out there (saw a post from dmax about his alt method but cant seem to find it) so it's really confusing me now..

again this is gonna be my first time bleeding a 99 323i M/T e46 or any BMW car so im loading up the info and getting ready this weekend..

Thanks in advance for the input..
