Recommended replacement interval for timing belt on 98 Land Cruis
Ok, here's the deal:
An accessory belt (commonly referred to as a serpentine belt or a V belt depending on application) is rubber and drives your accessories like power steering, air conditioning, etc. These are usually cheap and can be seen and replaced easily.
The TIMING BELT is also rubber, however it's job is much more critical. Basically, it times the bottom part of the engine with the top part of the engine. It is NOT seen without having to take a few things apart. It is NOT for the novice mechanic. However it is also usually not that expensive for the belt either. It's the intensive labor that's the cost factor.
Your engine is an "interference" engine. Meaning that if that timing belt breaks, then valves will contact pistons. That means ka-boom and major $$$.
You will not not a performance difference until the belt breaks. At that time it will be too late. Valves will be bent, pistons may crack, heads may be damaged.
The mileage recommendation on getting the timing belt changed is just that: a recommendation. They can last a lot longer, and sometimes not so long. As long as the belt doesn't break, you're good.
Seeing as how you've gotten twice the normal mileage out of that once belt, then I'd count your blessings and get it changed. Do I think you can get it done for less then $1500? Yes, without a doubt. Just price shop with other mechanics.
So the only question is, does your truck have any other major problems. If it's like most Toyota's, then probably not, which means it'd be worthwhile getting the timing belt done. The engine should last a long, long, time yet. Plus it's an excellent selling point if you want to ever sell that vehicle.
If you have other problems, then just wait til the belt breaks, because it will eventually, that's just how it is. At that point you can replace the valves and repair the heads and possibly pistons, or get a new or used engine to put in.
The cool thing is that while they go in and replace the timing belt, they can do a lot of other things very very cheaply, or at least, they SHOULD. For instance, they can replace that serpentine accessory belt since they have to take it off anyway. The water pump is also sitting right there.
So just be sure to ask them these options. It'll be a lot cheaper to get them all done at once, rather than waiting until they go bad and having to make a 2nd trip. For instance, get the timing belt done, and THEN finding out a month later your water pump is going bad and that they could have replaced it then...
In summary, if you like the vehicle, just get the timing belt done if it's due. And shop around and get it done reasonably. It'll be way cheaper than the head work and/or a new motor.
