I was really pointing that place out because I'd suggest not going there unless you tell him to just fix that one problem, and nothing else. It's worth a read when you have 20 minutes to blow. Take it to Stance Factory, they can fix this and they are closest to you.

first thing i would do if i was in your situation is to grab a screwdriver and tighten up all hose clamps for the cooling system, then i would check for wetness around the waterpump, if thats dry then i would check the rad and coolant reservoir for cracks/leaks.. but thats me.

a 'bolt' is to general... need specifics on where this bolt is.

Put a peice of cardboard underneath the car, look under and you should see the general area of where the leak is coming from. Than post your results! run your hand around the expansion tank check for cracks, I'm going to bet it's the water pump or expansion tank that is leaking.

+ 1 on Vanderheyden. Good guy to deal with.

The mysterious coolant leak may be the result of a worn o-ring on the Coolant Temperature Sensor. It's a pretty common problem according to other e46 posters. I fixed mine and after a month no leaks! Cost . . . wait for it . . . 50 . . . cents! BMW won't tell you the o-ring part number but this poster will:

Hope that fixes it. Some poor guy swapped hoses, the expansion tank, the radiator, then the sensor (with a new o-ring). At least he doesn't have to worry about those parts breaking for a while.

Start with the o-ring.

Pop by Autobahn East in Ajax during the week, no charge to check it.

I checked it, took out the fan to get a better look, hoses are fine, expansion tanks fine, only culprit is the waterpump, unable to see the leak, but it leaks onto the crank and drips down, reason he had more on an incline was because it was pouring out of the bottom cover on an angle. Easy fix.

^^sounds like waterpump or thermostat. You could also be leaking coolant form the HG.

There aren't too many clear, watery fluids in your car, that's almost always coolant (although rommel is right, it COULD be brake fluid, most people can tell the difference based on consistancy).

Also, there's no A/C fluid. Although its actually liquid in your A/C system, as soon as it touches oxygen it will turn into a gas, so you'll never see it puddling.

Good luck getting it fixed. If you're changing your waterpump i'd probably do the timing if its close to due.

Sounds like you need a cooling system overhaul.

Waterpump
Thermostat
Hoses
Belts

Might as well do it right and not have to worry about it.

[Adrian_Lindn]

Thanks for all the help and comments. Im going to change the water pump this week reason being the squeel i had is still there, meaning one of the bearings must be messed up in the water pump. I might was well change th wp since im almost at 160 000 km. You could tell it was wet underneath the water pump and thats where it was dripping from me and A Karski checked it on the weekend.

[Adrian_Lindn]

Can anyone else confirm that since i have this whistle noise it can be a bearing in my water pump?

[1bmw1]

I'm not sure what a 'whistle noise' is but if its wet underneth your water pump and it is making noise then it's more than likely to be shot. Keep in mind that its possible to hve a leak elsewhere and its just naturally pouring onto your waterpump making it appear that its leaking from there.

Went to my cousin at the Beamer dealership. Once i got there the leak was gone :SSSSS Yea my luck right?! Seems as if wherever the leak was it sealed it self temporarily. He saw some crusted coolant around the pump and thermo stat but cannot determine which one it actually was. I guess ill just have to wait and see...I say eff it im gonna keep driving. The leak only pours harder when im on an angle. FML
