how do i change the coolant/flush radiator in 2004 ford freestar

Open the petcock on the bottom of the radiator and allow the old coolant to drain.

Close the petcock.

To refill you will first fill the degas container to the cold fill range, leave the cap off the canister. Turn all of the heater controls to warm and turn fan to full. Idle the engine until the thermostat opens. Top off the coolant and put the cap back on. Idle at 3000 RPM for several seconds and then idle again for a minute or so. Check the level and then repeat this 4 times, or until heat is coming from the front and rear heat units.

If you want to flush the system you will have to remove the thermostat and hook up your flush system to the radiator hose at the thermostat housing. Follow the instructions on your flush system then put the thermostat back in. Follow the instructions above to refill.
