I'm very surprised to hear this. A good timing chain should have close
to double the life of a belt, or a minimum of 100,000 miles.

It seems implausible that the technology would have gone backwards here
that recently.

> I don't recall changing the water pump with the timing belt but I might have. When my water pump sprung a leak on the VW, I changed out the belt too since it had to come off anyway. They should hang the water pump off to the side of the engine since they tend to leak.

100% agree here, water pumps seem to have been placed as much for
convenience as the high cost of replacement.
