2007~2015 CX-9 Water pump problem. Possible engine damage?

:
Mazda cx-9 2008
gentlemen, the car is done. Oil filled twice and engine flushed. I lost 5 liters of engine coolant but I caught it in time and replaced the complete timing belt with the water pump. I think I will do another 100,000 km and sell the car. Thank you for your help.
