Below is an edited reprint of my response to a similar discussion for
this topic....
Try this listing of services, parts and recommended replacement intervals. If a part was replaced at the first 60K service and I specify a 120K replacement interval, that means I think it should be good until the 180K service. Search Key:

With the lifetime warranty on parts such as the remanufactured water pump, I let them go until they leak. Otherwise, you would have to buy them each service and basically forfeit the warranty. If the water pump is original and has no warranty I would replace it with a remanufactured unit that does have new seals, bearings and warranty.
I personally wait until the thermostat fails before replacing it since you can reach it just as easily by loosening the intake tube hose clamp at the throttle body and the two air cleaner lid clips and removing the cleaner lid and intake hose. It could last for years and the most common mode of failure is that it doesn't fully close, rather than sticking closed. It just makes the engine slow to warm to the normal range or prevent it. Neither is immediately hazardous to the engine.
The crankshaft position sensor (CPS) has shown the ability to last longer than 60K miles and usually more than 100K miles. Since I do all of my own work, I wait until it fails before I replace it just to save money. At your mileage, I would replace it. It certainly saves the effort later. My OEM CPS unit lasted 180,000 miles.
My OEM CID (cam) sensor was still going strong when I replaced it at 269,000 miles during a camshaft seal replacement. After seeing a new one, I can see why. It is rather robust and there are no moving parts and not much chance for any physical contact with the sensor wheel.
The throttle position sensor is also a long life component and incredibly easy to replace. Only replace it when it fails. Same for the coolant temperature sensor.
