Your vehicle has a timing chain which should only be replaced if it is damaged. No specific interval to replace it nor the water pump. If you suspect damage is done to the pump or chain, then you should have it inspected by a mechanic.

Thanks for the reply. I've never replaced a timing chain before or a water pump. Don't usually keep a car this long. What are symptoms of a bad chain or pump? Sound? Leaks? 58,000 miles.

Bad chain it wouldn't run, bad water pump it would leak coolant, cause horrible noise and overheat

Are you having a specific problem or just what your friend said?
The only maint. On the 1ZZFE VVTi engine is to change coolant every 2 years and plugs at 100k.
Of course change oil, brake pads as needed etc.
