if you feel you are a compitend shade tree mechanic you shouldn' thave to much trouble with changing the timing belt. YOu need to support the engine and remove one engine mount. My father and I did it ourselves on my car and it took us 4 hours, but we took our time and made sure everything was done right. The Ford service manual for the car tells you everything you need to know. make sure you read up first and then deside if you want to do it or not
