Toyota: 4runner timing belt replacement

Well, we don't do it unless its questionable or if the customer's asks
us. When I say questionable, this is based on years of working on this
stuff. You are on a 90K interval, they usually never fail before the
second belt is due. But the water pump, I'd do. On rigs where the
intervals are 60K, I'd do the water pump every other time I do a timing
belt (120K) but this is for an original OE water pump only. I have seen
those GMB aftermarket units fail before the belt was due. And rule of
thumb, if your doing a timing belt on any interference engine, replace
everything. This is all the Toyota V8's right now.
