The last time I filled a cooling system on a new motor was over 20 years ago, and I made a huge mess. I wanted to see what everyone's step-by-step process was for filling a new cooling system. I have a 351w based motor with the FFR aluminum radiator (has an upper and lower drain valve in it), and I have a fill point on the upper radiator hose as the highest point in the system with a 16lb pressure cap. I'm not running a heater.
Thanks!
