These are my figures:- Timing belt - $57.90, Belt tensioner - $86.33, Water pump and gasket - $88.00, Serpentine belt -$27.50. These are the prices I paid shopping around. During the replacement I also had the overflow coolant bottle (leaking) replaced along with the hose which was brittle at $72.30 plus the radiator cat $27.27. Thermostat assembly $117.95. Now the expensive part, labour came to $2,200 and I used my Ford Pass points which brought the total charged to $2,376.50. Now the car will outlive me! So now I have enough points to get quite a few oil and filter changes!
