flushing a heater core

Strokerscamp you really are a fountain of knowledge, my son has a Taurus and the heater core was plugged in it and unfortuantly I tried everything to clean it except the drano trick, I ended up replacing the heater core, Fortunatly he has a 98 taurus and you dont have to remove the dash on 97 and up so it wasn't too bad of a job, Has anyone asked if the thermostat has been replaced lately???

They also use a bypass hose on the older Taurus, like 97 - 99 model years. If the core is even slightly clogged, coolant will flow throught the bypass and not even go to the heater core. Make sure you pinch the bypass hose if you are flushing out one of those FERD cars.
