I have changed timing belts on several Toyotas-
All of the belts pulled around 90-100K still looked good-
However I am not willing to gamble on extending it-
Reason - Time, safety, convenience
(Had a friend that had a timing belt go during a road trip - left him stranded for quite a while)
When having a timing belt done- there should be no additional labor charges for the water pump- just the cost of parts & gasket or fipg - its fully exposed once you remove the timing belt
Often times there are very small leaks from the water pump gasket that - results in the slow build up / "crusting" of the red toyota coolant- Its often only noticeable when you open up the timing belt cover-
Build up of pink crap all over the place- Its quite common on the 3.4L
- No noticeable coolant leaks on the floor- since its slow process and small leak.
Appearance of the water pump is not always indicative of the leak since the leak is from the seal/ gasket-
The key here is saving yourself the future Loss of TIME by changing the pump at the same interval as the Timing belt.
Water pump & gasket for my Tacoma are only ~$88 bucks total from the dealer - Not really worth it to me to wait for it to fail and redo the entire timing belt labor again myself
