COOLANT BLEED ADVISE.

[expediant]

Ok, So heres the picture: I needed to replace my temp gauge sensor and i was having to drain some of the coolant off so i thought i would change the thermostat to a genuine BMW one............so all the car is back together now.

Ok So, i took the bleed screw out to replace the coolant and followed the 'haynes' advise to fill up until coolant came out of the bleed hole.

So, i have started the car up and all seemed well, but........... now the engine is overheating..........obviously when it gets to the red i switch off.

Tomorrow i am going to check the thermostat is installed properly as it was a bit of a bugger to fit.

BUT, CAN ANYONE GIVE ME CLEAR INSTRUCTIONS AS TO HOW TO CORRECTLY BLEED THE AIR FROM THE SYSTEM. I AM HOPING THIS WILL CURE THE OVERHEATING

ANY ADVISE.

There are a few DIY's here: http://www.geocities.com/e36rulz/DIY.html , which I've been reading because I plan to flush my system soon. According to these, if there is still air in your system your temp. guage will show overheating. But like I said, there are a few different DIY's on that page, read them all for different tricks for getting the air out of the system.

ALSO I JUST WANTED TO ADD THAT WHEN YOU FILL THE RAD UNTIL THE BLEED SCREW SPILLS OVER, THE WATER LEVEL IS TO THE TOP OF THE RAD AND IS NOT DROPPING................HOW CAN I AMKE IT DROP.

Idle your car with the heater on full blast, when the thermo opens, it will go down.
