That's another of those joyful jobs down under
When I had to tackle my alternator (after it seized upon shutdown and when restarted it shredded the serpentine belt) I was touching nearly 100k miles hoses, tensioner and belts so I made a Touch It Once project out of it all the way back to the rear engine hoses, heater hoses, heater control valve, tensioners, water pump, thermostat, idlers, fan clutch, fan and belts.
No more worries for me about any of those components in my ownership lifetime with this vehicle.
