ST Water Pump, have you had to change it and when Options

[hurley97]

I'm wondering how the ST water pumps hold up to see if its worth it for me to change it.

so here are my questions to you ST owners:
1. whats the regular service interval for the water pump?
2. have you ever changed your water pump?
3. was it because it went bad or just preventative maintenance?
4. what mileage was it done at?

There is no service interval for the pump. Most people change it when the timing belt is replaced since they are cheap, there is very little additional work, and you will have to repeat most of the work to replace the timing belt if the water pump fails at a later time. This is what I did around 80,000 miles. The pump may have been leaking a little but nothing major.

Also note that you can't really determine the condition of a timing belt by looking at it. They are usually replaced on a years/miles basis.
