i just rolled 91,000 miles, i replaced tranny oil, rear diff, regular oil change, brake pads/fluid, next i am changing the top/bottom radiator hoses and fluid. changed spark plugs at 70k, is there anything else that i am missing? would appreciate the suggestions

At 91K why not change the water pump and timing belt now. Its scheduled change is at 100k

i guess i was lucky at 76,000 miles i had a strange noice coming from the belt/ pulley.. took it in to nissan and found out it was the chain guide and had everything replaced under xtended warranty.... cost aprox 2,500 dollars for parts and labor..... i am wondering if they would have replaced water pump?? is that a standard thing or would they leave it as is. where is the water pump located?
