I have a 97 523i
Today after driving 100miles, leaving the motorway and slowing at lights the engine overheated....!
Temp went up and lite the warning light.
Turned the engine off and took a look under the bonnet to find steam and coolant pouring onto the road but could not locate where it was comming from.
Car has been allowed to cool and then i started to fill the coolant back up, i believe i have removed the air from the system by using the two air release plugs at the top (1 by the filler cap and the other on the top feed pipe).I started the engine and allowed it to heat and then in course to pump the water round.... the water level dropped and i then topped it back up.
The problem is that it continues to over heat but it does not leak now and there is no steam.
Also now the heating within the car is cold even when set to max 32 degrees.
Being cold in the car may suggest a airlock and cause it to continously over heat?
Does anyone have any ideas where it may have poured it's coolant out from? When i looked the whole of the front of the engine was wet from the condensation of the steam, the coolant was pouring from the front left of the engine bay but from no obvious location.
I know it could be coming from anywhere and this post is a bit vauge but i will try and give as much info as possible.
I had wondered if there was a possibility if a faulty thermostate... not allowing the water to circulate and therefore overheat...? But then how did the coolant get out...Is there a kind of pressure valve that will dump it in this kind of emergency?? I really dont know and am just scratching at ideas.....
Any advise is greatly appreciated!!
