The Serpentine belt drive the water pump, power steering pump and alternator all at the same time.

service your radiator and change the side tanks. if not sure about the health, then change new. also newclip for the hoses, radiator rubber mounts. and got chance the crank pully oilseal at the engine side if not leaking. tensioner pulley's all no need. change the belts yes. while u are there do a flush for the power steering oil.

What would you u do for cooling system preventive maintenance at 120,000 Km?

Is Expansion tank replacement necessary?

THANK YOU GUYS. Appreciate your help !

yes, if you are the person which is going to overhaul the the whole cooling system, might as well. you see, the whole cooling system pressure is equal at all points, so doing all n leaving the expansion tank, it will be on a 'first' thing to go..if not over a short period.

I rather have the peace of mind for the next 3 years.
