Default Maintenance schedule for 2010 Impreza 2.5i. Water pump/timing belt?

Hey guys,

I checked my physical owners manual and found the maintenance schedule but it said nothing about water pump or timing belt. I found it odd

http://www.mytimingbelt.com/

Says 60k miles for 01-06 models
and 66k miles for 07 >

This site also lists additional information about auxiliary drive belts and such. Nothing about the water pump though, but I believe its usually changed at the same time.

Interesting web site.

I know that this question is out of scope for this thread, but I notice for the 2012+ Impreza with the 2.0 engine, the site says "N/A" for when to replace the timing belt. I believe that's because the new 2.0 engine uses a timing chain, right? If so, can one assume that the timing chain is good for the life of the engine? And if so, do we just replace the water pump on an as-needed basis?

They won't give you a maintenance schedule for the water pump. Generally, the water pump is replaced whenever you do the timing belt, since it takes a lot of disassembly (in most engines) in order to change the timing belt, and the cost of installing a new water pump is not that much in addition to the other work.

If you don't replace it, and the water pump were to fail, the labor cost to disassemble the engine to replace it is more than the cost of the pump, which is why most mechanics recommend replacing both (you get two new parts for the cost of 1 labor).

Also, of course, a failed or failing water pump can overheat the engine, causing total engine failure.
