+1,i would agree, any time the timing belt is replaced, even at our dealership we recommend the water pump should be replaced at minimum. the others are nice only since your already in that area, and its apart anyway it doesn't hurt.It's a full weekend DIY. On myotor we did belt, water pump, thermostat, tensioner, rollers, cam seals, crank seal, coolant. If you search you can find at least two threads in which I beg for help
and mercy. Good times.
