My mileage is 115000 and I am getting the timing belt replaced. The shop quoted $440. to install the Gates timing belt kit with new idler and tightener, a new valve cover gasket, and a new serpentine belt. If I want the water pump replaced while he has it apart it will be another $100. He said the water pump can be changed later without having to remove the timing belt but it would be easy to do it now while it is apart. My questions are how do these prices sound and does anyone have a mileage figure when their water pump failed in the Zetec. Thanks rd
