How do you do this since the stock one had no cap and bleeder screws, but this has cap and no bleeder screws?

 

When I installed mine, I filled it as much as I could, and then started the motor running with the filler neck caps off (the one by the engine, which is higher and the one on the rad) and watched the bubbles come out, and kept adding fluid until there were no more bubbles. Then I sealed the radiator and continued the process at the upper fill neck. There might be a little air trapped in there, but I doubt it. I've never heard my low coolant buzzer even on hard corners, and the fluid level in my overflow tank has never changed.

 

Thanks, how much did you fill it up though, all the way to the filler neck or should there be some air in the system to allow for expansion?
