I think it's better to disconnect hoses and flush manually. This avoids a potential failure/leak from the Prestone fitting. More important, it lets you selectively flush the system as it is important not to flush debris into the old Chrysler ACC servo (pre 1981, I think). The smooth ended hose nozzles sold at dollar stores fit the heater hoses nicely for back flushing the heater core and other hoses (just don't flush into the ACC servo). You can/should flush the servo or monovalve but with clean water only. Then flush the radiator and motor.

Where, exactly, should it be spliced in to the system? Or is it not a good idea at all?
