Does This Debunk the "Coolant Can Flow Through the Radiator Too Fast" Idea???

Yes, that is correct and what keeps it in longer, the restriction caused by the thermo. No matter how fast you pump it the thermo only allows so much coolant to get by so you can keep a minimum operating temp. I think the best way to look at this is we all have different views on the matter. If your system is working, it's because the whole system is in sink. If the system is not working, I would look for a clog of some kind first [ block thermo rad.] before I started messing around with pullies. A lot of what NBT says is correct, I just think its pretty shitty to say the things he says to people who disagree with him. We are all here to discuss things and maybe offer some help to others, not put down other members.
