Is it best to replace the water pump when replacing the timing belt?
Yes. Might as well. The cost of the water pump is negligible when you pay labor to do the timing belt at the same time, especially on a 13 year old car
I would ur already right their at it makes sense.
yes, it is right there and you don't want to have to pay twice, I have done many of them both ways, and I have done many of the ones I did just a belt on twice because the pumo started leaking and if it gets on the belt then the belt is no longer good anymore and is more prone to breaking
I don't know about your car specifically, but on a lot of Japanese cars, you have no choice. They seal with a crush washer, and you have to rebuild the pump to replace that crush washer. If you don't it WILL leak, and in fairly short order.
