Water pump replacement, do it before it goes out?

You may want to upgrade the oil pump while you are in there. I wish I did it when mine was apart. They make an upgraded unit with higher spring pressure which really helps on high mileage cold starts. The cam phasers tend to rattle on startup due to poor oil flow.
That's a good idea. Thanks, I appreciate that.

125k would be my interval. I've seen them go as early as 70k but the majority I do have around 150k on them. As long as your engine is nice and clean on the inside I'd only replace the water pump and timing chain at 100-125k. Then after 200k do all timing components. Those phasers/ solenoids are a little pricey and don't need replacing at 100k if the engine is clean. If you have sludge from a neglecting previous owner then replacing all isn't a bad idea.

That's good to know, thank you! I was thinking about doing it since the labor is about the same but I'll just ask the shop to look at it and if it needs it then have it done.

heres a youtube video that talks about the oil pump upgrade

 






I had no idea about the water pump issue until about 200000 miles. I did a preemptive replacement then. The old pump looked to be in pretty good shape, but the shaft was not spinning as freely as it should

Im now at 380,000 miles and Im waiting for a mechanic to call me with a price to do it again. This time I think its the timing chain guides that need to be replaced
