This is how to change the coolant for a Ford F150 5.4L 2004-2008. I used a little over a gallon of coolant concentrate and a little over a gallon of distilled water. Doing this job is fairly easy and you really only need a bucket. If you are going to use a socket on the plastic drain plug BE GENTLE it is plastic and fragile.
