Context: As a result of two years of hard service on awful roads , the tie - rod ends and front shocks needed replacing when I got the car back in ' 06 . Beyond that , it 's needed front rotors , pads all around , and a water pump . I ' m pretty good about oil changes every 3 - 4 K , and while the water pump was out I asked for a fresh serpentine belt .

Question: What might be the reason I asked for a new serpentine belt ?
Options:
0. Because the belt needs to be removed before the rotor is replaced .
1. None of the above choices .
2. Because the water pump needs to be removed before shocks are removed .
3. Because the water pump needs to be removed before replacing the rotor .
Answer: 1
