Did this today, bilge pump and 5 gal. bucket. Definitly the way to go.
That method sounds super easy and efficient. But the T-valve to my headers cannot be shut off. It is a spring and checkball style t-valve from Rewarder Custom Headers that opens by water pressure. It is closed at an idle but after about 1500RPM's it starts to open when water pressure increases. Could I still use this method of winterizing and not worry about the t-valve or the headers?
