Fill radiator expansion tank.
Start engine. Run till warm. (To open thermostat)
Unscrew bleeder screw.
Squeeze hoses if necessary to get coolant to move. (may not be necessary)
See coolant come out of bleeder screw.
Add more until coolant coming out of screw is free of air bubbles. Make sure level is correct.
Stop engine, let cool. Check level and correct if necessary.
Run to warm to check for overheating. Needle should be pinned dead on center.
: Anybody have a good way to bleed the coolant system on a m50 motor with bleed screw on radiator. Bentleys does not seem to good.
