    In order to get the most of the coolant out of the engine, which system works better. suctioning or pressurizing. Any expert opinion. Thanks

    I would do a power flush with water and then let it gravity drain. I don't think you'll get ALL of the fluid out but if you want to get 95% out do a water flush. Then start adding the antifreeze for the proper mix and fill with water. Works for me.

    You cant drain the front of the motor, so regardless of anything you do, short of dumping the car upside down the engine is still going to be half full of water.

    draining the radiator is one and half gallon and the rest is three and half gallon which stays inside the engine block. It is almost impossible to reach the engine side block screwes to drain the blocks, but thinking of sending suction tube down into the block and suck the fluid out as much as possible. what you think. the car is 550.

    You will have fun getting to a proper 50/50 antifreeze mix if you water flush but are unable to drain completely.

    I thought that was half the fun of working on cars, doing the seeming impossible. I often recall the words of a 70 year old aircraft mechanic I worked with. A man put it together, a man can take it apart. Get to the block drains, thats what theyre there for.
