Assuming that you've already vaunted the head gasket and the motor is together you can simply remove the plug(s) and turn the engine over. Don't let it start or run but once it turns over a couple of times the coolant will be pushed out during the compression stage.
Warped/cracked head or gasket-it's hydrolocked
Is there white smoke coming out of your exhaust pipe , even when the engine is warmed up? That's the most obvious sign that coolant is getting into an engine cylinder from a bad head gasket , a warped or cracked head
Remove the engine, place on an engine stand. Remove heads, oil pan, pistons, main caps and remove the crank.Remove the engine, place on an engine stand. Remove heads, oil pan, pistons, main caps and remove the crank.
Quite simply you have to remove the pistons. first drop the oil pan second disconnect connecting rod end caps third either remove crankshaft or remove cylinder heads then finally remove pistons. removing pistons are commonly removed from the bottom of the engine. they are pushed out of the top where the cylinder heads sit. Once removed you can replace the rings and then you have to get a piston ring compressor to reinstall the pistons.
a press
Elbow grease
Yes but I wouldn't use it for anything else after that, seeing as antifreeze is very toxic
Remove wheels then push back the pistons then remove calipers and brackets then the rotors.
You remove the cap and pour it into the coolant bottle.
Jack up and block the car remove wheel pry back the caliper pistons with out breaking the pistons then remove caliper and pads.Reverse to install and pump brake pedal until it gets hard.
Water, or just light them on fire.... then add water
To change the antifreeze on a 2003 Alero once the car cools remove that radiator pressure cap. Pour in a gallon of pre mixed coolant.
