A flush "T" installed in one of the heater hoses flushes the engine via the
heater cores and the bypass hose which aren't controlled by the thermostat.

What it doesn't flush the radiator or the long coolant lines running between
the radiator and the thermostat housing and coolant distributor if the
thermostat isn't open.

Opening the bleeder on the radiator will flush out the long tube between the
coolant distributor and the radiator, but I don't understand how you can
effectively flush a 12' long hose with a 1.25" id through a 1/2" round
opening located about 2' above the hose.
