Unlike in a couple of other threads I searched, I have a specific question: If I'm looking at a +/- 90,000 mile 100, what will need to have been done/what will I need to do to make sure it's good to go for the next 90K? (I just bought a 90K mile 97, and the 80 section of this forum told me everything I needed to know in advance of my purchase....now I need to draw from the experience of the 100 section of this forum)
Timing belt and water pump needs to be changed at 90K miles. I would plan on changing all fluids to synthetic's and change all filters. Check the boots on the front axles for deterioration. Rust can be a problem depending on where it spent its previous life. Run a carfax report and don't buy anything that does not make sense on the mileage or has a accident record. I'm sure some others can add more things to plan on.
When they change the timing belt, have them replace the camshaft oil seals, the accessory drive belts and add NEW coolant. Most stealerships catch your old coolant and reinstall. The spark plugs will need changing at 120k. And I would have the auto tranny flushed until clean fluid is flowing. May take 2 or 3 flushes.
Just curious (and not to hijack a thread) but why are stating that the timing belt needs to be changed at 90k? I do not recall anywhere stating this should be done. Last time I checked, even Toyota did not express an interval. 90k sounds good. Just interested in the reference.
To your question, check the 4x4 system on the street to hear/note the condition of the front birfields. Make sure there is no coolant leaking from the rear of the head where the coolant leaves to enter the firewall ( I had that issue). Make sure all diff locks work if it is a 98 or 99. Make sure the antenna works and can be manually operated/controlled. Make sure the coolant looks healthy. These models have to be flushed frequently. It has not happened to me but I have heard of VERY costly repairs having to do with a poorly maintained radiator.
recall seeing it in the OM and the FSM as well as the service sechudal. I am almost positive its a 90k.
