2 clamps literally

they will give you one
get a bottle of coolant
plug everything back up
undo your rad cap
pour coolant in
start the car
as it gets to about the 1st line or half way to the middle so 1/4th of the temp gauge turn the heater on full blast and while its being bled squeeze the upper rad hose and the lower one (once the lower one has heat in it) to get the air out, also squeeze the heater core hose once it has heat in it to bleed out the air, once the fan cycles through (twice) top it off and put the cap on
