Cooling system burp

5.0's 4 ever said:

You will fill it thru the fill plug at the coolant crossover tube. Leave the coolant resevoir cap off, pour as much coolant as you can into the crossover tube until it reaches the top, in theory by doing this its suppose to get the air out of the system but it never works perfectly. Screw the plug back in, I leave the resevoir cap off, start the engine, put vents on heat just to monitor when the thermostat has fully opened, I let the engine idle the whole time until the thermostat opens.

since you didn't mention it in your post, you might want to do a cooling system flush while you're at it
