Hi all, I've been trying to figure out which pump flow coolant pumps have our truck oem 2007 5.4L 3V, but I have not gotten anything. Anyone have any idea exactly pumped flow? And if there is a pump motor that drives these higher coolant flow. I read somewhere that the 2005 Navigator drive more flow but I'm not sure of that and if they fit in our engines. I read that Meziere pumps produce higher flow but life is short and where I live I can not afford to have a short shelf life. Thank you.
