100K Maintenance Q's from the new guy

[Aaron Fitch]

Hello everyone. My new2me 98 4runner has 101,533 miles and I am having the 100,000 mile maintenance requirements completed by my mechanic (Oil Change, Transmission fluid change, Transfer Case Fluid Change, Differential Fluid change [front & back], spark plugs, spark plug wires, fuel filter, grease the drive shaft and any other undercarriage component that needs grease, belts, [air filter is good], & PVC valve).

Have I forgotten anything? Should I replace the alternator as it is the original? Should I change the oxygen sensor(s) even though I had the Fuel System cleaned?

I would love to hear your advice.

Joy & Peace,
Aaron

That sounds pretty good. What about your radiator fluid, has it been changed lately? Also, the timing belt, it should be changed at 60,000 on your model and 90,000 on my 2001. A lot of people tend to forget aobut that sucker since it is quite expensive to change and they tend to hold up for a long time. If it hasn't been done and you decide to change your timing belt, they usually change your water pump, all the regualr blets and your raditator fluid.

A good thing about the 3.4 V6 is that it is a non-interference engine, which means if your timing belt breaks, you won't ruin your engine. Your car will stop, but your valves shouldn't be bent.

Thanks Peter78

Peter78,
Thank you for your quick reply. I forgot all about the coolant so I'll get that done as well. The previous owner said they had the timing belt changed at 60,000 miles. They took great care of the vehicle so I am leaning towards tusting their word about the timing belt. If they did change the belt at 60,000 miles I'd have to get it changed at 120,000 miles. Does that sound about right? I'll call them up and ask them to ask them for certain when they had the timing belt changed just to make sure. Thanks again.

Joy & Peace,
Aaron
