We put this matter as **WARNING** Has your timing belt been changed at the correct interval? after every service. In the past we recommended mileage intervals but got ourselves into trouble, the best option is to always put the onus back on the customer to take responsibility, as there are so many permutations involved in timing belt replacement. When belts break and customers find out the cost of replacement they will find any excuse of putting the blame on the garage or trying to blame someone else. Its the culture we live in NEVER my fault even though I never read the manual.

We as everyone else cost all timing belts with water pumps in some cases even if they are not driven by the timing belt as we have had a number of ZETEC engines fail the water pump and though not driven by the belt require the belt to be removed to replace the water pump. Water pumps should be just standard fare when costing timing belts.
