If you google BGB(big geen book) you should be able to find it online.

Otherwise it's not hard to describe it, both of the bleeding valves are accesed in the frunk(front trunk) you will need (2) 3-4ft lengths of 3/8iirc clear hose. One of the valves is locates next to the radiator by the left side headlight. The other is mounted on the firewall in the center where the heater core lines connect. They are black plastic and have a white screw that you use a large flathead screwdriver to open. You will need to have your car at operational temp and on level ground. All you need to do is connect the clear lines onto the valves and I loop them through the loop on the hood where the latch grabs it; then, with the car running open them up until they fill with coolant, minue usually filled about a foot of the clear line, then you just close them when the bubbles stop!
