Running hot

[Moz]

Hi,

1991 325i

After the car is running for 30 minutes, the needle starts to creep past the halfway point towards the next line. Heaters blew hot correctly.

Flushed the coolant and have tried to bleed but nothing comes out of the bleed screw, what's the best way to clear the screw if there is a blockage? Viscous is fine, cannot be stopped when running once at operating temperature.

Turning from cold to hot on the dial makes no change.

Blowing hot now since new coolant change but still creeping over half.

Next steps to check?

Thanks
