My 325i is drinking water !

[challe]

I just found out that my 325i is drinking
water ! Just a little over 100 ( swedish miles ) ,,,
But what could it be ?
The m50 Engine is not overheating and it works very well !
Anyone got any idea ?

I assume that by "drinking water", you mean the coolant is disappearing? This may be a no-brainer, but have you checked for any leaks? How long has it been acting up?

[challe]

No leaks as I found !
It have acting like this since I bought it .......
But as I told .. No problems with how the engine work´s !
But the " coolant is disappearing " ( My great English lol-lol )

The owner before me change the Heather ( you know that little
cooler in car - to get hot in winter )
Could it be some "Air"problem ?

Sorry for my bad English - I hope it will be better !

Have you tried topping off the coolant?

You should only measure coolant level when the engine is cold.

Hi Autotechnica !

I will do that once more !
yes I only will check the Coolant level when its cold !

Could it be some air in the system ?

Thank you for helping !

It never hurts to check for airlock.

Just unscrew the vent hole (it's the one beside the filler cap, unscrew with a phillips screw driver). Unscrew the filler cap as well. Start the car, turn the heater to full blast. Check the coolant level and make sure it's at the top "COLD/KALT" mark at all times, top off as needed. Once you're done topping off, put the fill cap back on. Leave the vent screw out. You should see the coolant bubbling out of the vent hole. After it stops bubbling screw the vent screw back in. See if that sovles the problem.

check if the cap is tight, and make sure you have a 50/50 mix

Hi CiscoKid !

It will be a good idea !
Thank you !

I hope it's not a broken head gasket. Did you see white smoke in your rear mirror?

[GnnSk8]

if you baught it used it could have overheated before. And when BMW engines overheat they tend to burn coolent because the cap can easily melt. So maybe if you havn't check out carfax. Get your VIN# (open your drivers door and look in the part that is normally closed)

It's too bad, Carfax wouldn't work in Europe............

[Autotechnica]

Carfax wouldn't tell you if the engine overheated either. It only reports whatever the owner reports. He could have crashed the car into a wall, towed it to a shop and had it fixed, car fax wouldn't tell you this.

In simple words, Car fax is only useful to a certain extent.

Another thing is i had a very similar problem to this in my 93 325is and it turned out that by removing the black plastic shroud that covers the radiator i found that the small hose running between the coolant tank and the top of the radiator had a small (1/2 cm) crack that at high pressure ( high speed, high rpms, etc) it would leak coolant that would hit the engine blcok after hitting the fan and being shot onto to engine blcok and it would evaporate with the high heat.
