I'm having timing belt service done tomorrow, and as of yet not entirely sure if I'm keeping the truck. I had one place (the place that removed the cam cover and inspected the belt for me) quote about 700.00 including the belt, belt "kit", wp, camshaft seals, tensioner and some other seals.

I thought for sure the previous owner had done this with all of the other excellent service this truck had, but the inspection revealed that the belt is literally hanging on for dear life. It's visibly cracked on the SURFACE side. I believe I had found a post on this forum that mentioned condition can't be inspected visually on these, but this one was definitely obvious.

Is there such a thing as just doing the belt by itself, or does the labor to get all the way in there make it to where the cost of the oil seals, tensioner and such are a "may as well do it" type item? Those bits aren't terribly expensive, so if they don't carry any real labor on their own, I may as well throw them in. I know the water pump is optional, but I'm trying to figure out how much else besides the belt itself contributes to the labor cost.

Right now I have a quote from the Toyota dealer for 649 minus a 10 percent coupon. I figure another 100.00 off that if I scrub the WP installation. I assume that's about as cheap as you can get without doing it yourself, so does that mean the Toyota procedure doesn't invlove replacing all those various seals and the tensioner? Or does doing a Toyota TB service ALWAYS include that?

Essentially, once I make my decision on whether I'm going whole hog with this service that'll decide for good whether I keep the truck. 50/50 right now, but there's no way around doing the tbelt at this point and it must happen. This is on a 2000 LX w/150k, apparently on the original belt.

I just had the timing belt done on my LS yesterday, which has 100K miles and almost same engine.
I replaced the following:
1) TB
2) Water pump
3) cam seals
4) main serpentine belt

The water pump was beginning to leak coolant and crust over slightly. These water pumps do not last the life of the engine. If coolant starts leaking, the pump will seize eventually and break the timing belt.
So most likely, if you don't replace the water pump when doing the TB job, you are kind of wasting money on replacing a TB.
Pulleys do not need replacing before 200K IMHO unless the technician rotates them and hears noise from the bearings. I will replace all pulleys on the next TB at ~200K on my 100 and LS.
 
The minimum for this exercise is:
- Timing belt
- TB tensioner
- Water pump
- Serpentine belt
If the cam seals and crank seals are not leaking DONT let them touch them. Mine are still bone dry at 230K miles.
Check the pulleys, and only replace if the bearings are worn.
