Hi
I have fitted a new radiator and filled with water, ran it without the cap for a while but it keeps wanting to boil over! i have undone the vent screw to try and expel any air, had the heater on but only cold air coming through with the temp gauge getting near the red!!
Car is a 91 318i cab

Any suggestions appreciated!!

There is a way of bleeding the cooling system.

I'm guessing yours is the m40 engine?

If do mine was m42 but the same way applies as the whines are based on the same design.

The link may help
