Help With Cam Belts...?

[Luke W]

Guys I'm picking up a is 200 sport soon and I don't think the belt has been done and its on 95000

Have had a look around can't seem to find much on it:

I'm a little confused because different kits seem to include different things....

Obviously I want the best for the car, I have found these kits could anyone help me out:

This kit seems to be one of the best its by gates... what are the 4 bolts included? im assuming they are for the pully for the water pump?

Thanks for your help,

The four bolts on the first one are to fit the pulley wheel onto the water pump. Have you tried carparts4less? Just put in your reg and you will get recommendations, free delivery and discount. Even if just to price check have a look. Good luck and enjoy the car.
