I would stick with the blue/green coolant. Unless it already had red in already. Apparently they are not to be mixed. The bleed screws are as follows:
1.Back of the cylinder head above the thermostat elbow, a approx. 3inch long round tube with a cap screw on the end.2.On the firewall next to the brake booster is a plastic elbow with a pipe comong out the bottom. On top is a cap that looks like tyre valve.
