90K Service

Hello,

I just bought a 02 4Runner with 92000 miles on it. In a previous post someone mentioned taking it in for a 90K service which would include replacing the timing belt and water pump. However I just read in another thread that many think this is overkill;

I'll probably do it anyway just to be on the safe side. I'm not a mechanic but did replace the timing belt on my son's '86 Nissan 300ZX not long ago . I'm wondering if I could do this myself on the 4Runner... I would need a good manual, does anyone know where I can find one? Where could I find out what needs to be done at the 90K service? Thanks.

If you go ahead with the timing belt replacement, post back on here how it went and any updates/advice/criticisms of the install and of the write up posted above. I may need to change my timing belt again, almost at 200k and the last time it was changed was at about 100k.
 
FWIW, my waterpump was leaking a bit I had a small pile of dried coolant sitting above the crankshaft.

I did thermostat, waterpump, belt, and both the cam and crank seal.
My advice is to order the parts on line to save change, even if your not going to do the work yourself.
A short list of online OEM parts can be found here. :hatsoff:

It's not overkill. It's a mother to get to the water pump so most people figure since you are already in there while replacing the timing belt, might as well replace the water pump. If the water pump were to fail and lock up it would probably destroy the timing belt.

IMO, overkill is replacing the idlers too. Probably a good idea to do those every other belt replacement.

I think he meant overkill to do at 90K. I did mine at 120K and I think that's a good number. I also agree on idlers. The ones I took out look as good as the ones I put in. Next time I will only inspect idlers, and if there is a problem, one of those goes back in. And yes, definitely do the water pump. As far as I can tell, WP failures are far more common than TB failures and what TB failures happen are because of leaking or seized WP's.

Yes that is what I meant - overkill to do the TB at 90K. I agree if you were to do the TB you might as well do the water pump at the same time. I think I'll do both in a year or so, the truck would only have around 100K on it at that point.
