Soak it with Pb Blaster or any rust bust, try taking the entire fitting out not just the bleeder screw, also in the future always post the year and engine.

oh ok ya its the bleeder screw holder fitting the screw broke right off

sorry is the Lumina 91 3.4 engine

oh by chance how do u loose the siezed head light screws on same car i cant ajust them and i put wd 40 in the shaft area but no luck

WD 40 is no good for freeing up rust, Seafoam or PB blaster and let is soak for while.

[comet240]

oh i thought WD 40 was always to free up rust

will seafoam and the PB stuff be sold and canadian tire?

so why does the headlight screw sieze up? its pain in ass i cant adjust the dam headlights i dunno why they make it a 90 screw style lol
