Some repairs on Ford vehicles are fairly easy and safe to perform without expert help, while others are more challenging. Furthermore, some repairs are potentially dangerous to people without relevant expertise.
Drivers can learn to perform a number of basic repairs and maintenance work on their own. Changing a car's oil and air filter, for example, is fairly easy and safe, and it's unlikely to damage the vehicle. Changing a timing belt is generally safe and only moderately difficult; mistakes, however, can damage and even destroy the engine, so it's often best to hire an expert. Changing a battery is fairly simple and unlikely to damage a car, but mistakes can lead to severe personal injuries, so guides typically recommend hiring an expert.
