    "new" way to bleed the cooling system

    Saw a post on this website for a different way to fill and bleed the cooling system that worked really well for me...couldnt find it again to bump so here it is. connect a clean plastic oil transfer pump to the radiator end of the surge tank return line and the other end into your container of coolant. Make sure the connection is tight so you dont spray coolant as you pump...pump until the surge tank fills up from underneath...this seems to force all of the air in the system out through the surge tank. Once I was done I ran it with the heater on to operating temp, revved it a couple times, and cracked the bleeder a couple times and she was good...even spotted checked the bleeder over the next couple of days and nothing
    may you rest in peace, or pieces, whichever comes first

    here's how I do mine, works every time:

    Fill coolant system as much as possible. Open heater controls all the way.
    Start the car, leave the bleed screw open, leave the resivior cap off.
    Hold the throttle open a bit to get it to "suck" coolant into the motor. Fill resivior as the level goes down.

    Keep filling and watching the bleed screw. Once it starts to get hot, the level will begin to rise a bit (temperature expansion). It's done when the bubbles stop coming out the bleed screw and the overflow from the radiator is flowing back into the resivior at full force.

    Before the resivior tank boils over, put the cap back on. Done.
